Renal Tubular Disease

Renal tubular disease is a significant health condition affecting the kidneys of companion birds, characterized by dysfunction or damage to the renal tubules that are responsible for filtering waste products and maintaining proper fluid and electrolyte balance. This condition represents one of the most common forms of kidney disease encountered in avian medicine and can affect birds of virtually any species, though certain species demonstrate higher susceptibility due to genetic factors, dietary considerations, and environmental influences. The kidneys of birds play an essential role in overall health, and when the tubular structures become compromised, the consequences can be far-reaching and potentially life-threatening if left untreated.

The causes of renal tubular disease in birds are multifactorial and can include chronic dehydration, exposure to nephrotoxic substances, bacterial or viral infections, nutritional imbalances, and age-related degeneration. Unlike mammals, birds have a unique renal system that combines mammalian-type nephrons with reptilian-type nephrons, making their kidneys particularly sensitive to certain insults. The disease may develop gradually over months or years, or it can present acutely following exposure to a specific toxic agent or severe infection. Understanding the underlying cause is crucial for developing an effective treatment strategy and preventing further kidney damage.

The impact of renal tubular disease on an affected bird's health can be substantial, affecting everything from energy levels and appetite to feather quality and reproductive capability. Birds with compromised kidney function often experience a decline in overall vitality, may develop secondary complications such as gout or electrolyte imbalances, and face an increased risk of systemic illness. The severity of clinical signs typically correlates with the extent of tubular damage, and early-stage disease may present with subtle symptoms that owners might easily overlook. This makes awareness of the condition and its early warning signs particularly important for bird owners.

While renal tubular disease represents a serious health concern, many birds can be successfully managed with appropriate veterinary intervention and ongoing supportive care. Early detection significantly improves treatment outcomes, as intervention before extensive tubular damage occurs allows for the best chance of preserving remaining kidney function. Avian veterinary care is essential for accurate diagnosis and development of an individualized treatment plan, as the specific underlying cause must be identified and addressed. With proper management, many birds with renal tubular disease can maintain a good quality of life for extended periods, though ongoing monitoring and lifestyle modifications are typically necessary.

The primary causes of renal tubular disease in birds encompass a wide range of factors that can directly damage the delicate tubular structures of the kidneys or gradually compromise their function over time. Nephrotoxic substances represent one of the most common causes, including exposure to heavy metals such as zinc and lead, certain antibiotics including aminoglycosides, and various household chemicals or environmental toxins that birds may encounter. Chronic dehydration, often resulting from inadequate water intake or excessive water loss, places significant stress on the renal tubules and can lead to progressive damage. Infectious agents, including bacteria such as Chlamydia and various viral pathogens, can directly infect kidney tissue and cause tubular inflammation and necrosis.

Genetic and species-related factors play a significant role in determining which birds are most susceptible to developing renal tubular disease. Certain species, particularly budgerigars and cockatiels, appear to have a hereditary predisposition to kidney problems, with some genetic lines demonstrating higher rates of renal disease than others. The anatomy and physiology of avian kidneys vary somewhat between species, and these differences can influence susceptibility to various forms of kidney damage. Birds from genetic lines with known kidney problems should be monitored more closely throughout their lives, and breeding decisions should take kidney health history into consideration.

Environmental and husbandry factors contribute significantly to the development of renal tubular disease in companion birds. Diets that are excessively high in protein or contain inappropriate mineral ratios, particularly excessive vitamin D3 or calcium, can place undue stress on the kidneys and promote tubular damage. Poor air quality, inadequate humidity, and temperature extremes can all contribute to dehydration and kidney stress. Birds housed in environments with galvanized metal cages or hardware may be exposed to zinc toxicity, while those in older homes may encounter lead-based paints or other toxic materials that accumulate in kidney tissue over time.

Several risk factors increase the likelihood of a bird developing renal tubular disease throughout its lifetime. Age is a significant factor, as older birds naturally experience some degree of kidney function decline and are more vulnerable to additional insults. Birds with pre-existing health conditions, particularly those affecting the cardiovascular or endocrine systems, may be at increased risk for secondary kidney involvement. Obesity places additional metabolic demands on the kidneys, while chronic stress and immune suppression can make birds more susceptible to infectious causes of kidney disease. Previous episodes of kidney disease or exposure to nephrotoxic agents may leave lasting damage that predisposes to future problems.

The mechanism by which renal tubular disease develops involves progressive damage to the epithelial cells lining the renal tubules, which are responsible for the reabsorption of water, electrolytes, and nutrients from the filtered blood. When these cells are damaged by toxins, infection, or ischemia, they lose their ability to function properly, leading to inappropriate loss of essential substances in the urine and accumulation of waste products in the blood. The avian kidney has limited regenerative capacity compared to some other organs, meaning that significant tubular damage is often permanent. As more tubules become compromised, the remaining functional nephrons must work harder to compensate, creating a cycle that can accelerate overall kidney decline.

Early warning signs of renal tubular disease in birds are often subtle and easily overlooked, as birds instinctively hide signs of illness as a survival mechanism. One of the first changes owners may notice is a gradual increase in water consumption, as the damaged kidneys lose their ability to concentrate urine effectively, leading to increased thirst to compensate for excessive fluid loss. Simultaneously, there may be an increase in the volume of urine produced, with droppings appearing more watery than usual. Mild lethargy or decreased activity levels may be present, though birds often maintain relatively normal behavior in the early stages of disease. Changes in appetite may be subtle, with some birds becoming pickier about food or showing slightly reduced food intake.

Common symptoms of renal tubular disease become more apparent as the condition progresses and kidney function continues to decline. Polyuria, or excessive urination, is one of the hallmark signs, with the urate portion of droppings often appearing more liquid or the overall dropping becoming increasingly watery. Polydipsia, or increased thirst, typically accompanies the increased urination as the bird attempts to maintain hydration. Weight loss may become evident despite seemingly adequate food intake, as the body struggles to maintain proper nutrient balance. Feather quality may decline, with feathers appearing dull, dry, or developing stress bars that indicate periods of metabolic disturbance.

Behavioral changes associated with renal tubular disease can provide important diagnostic clues for observant owners. Affected birds often become less active and may spend more time resting on the cage floor or on low perches rather than engaging in normal climbing and play behaviors. Appetite changes are common, with some birds becoming increasingly selective about food choices while others may show complete loss of interest in eating during periods of more severe illness. Vocalizations may decrease in frequency or intensity, and birds that were previously social may become withdrawn or irritable. Some birds develop changes in their sleep patterns, either sleeping more during the day or appearing restless at night.

Physical signs of renal tubular disease become more pronounced as the condition advances. The droppings undergo characteristic changes, with the urine component becoming more prominent and the urates potentially changing color or consistency. Some birds develop a swollen or distended abdomen due to kidney enlargement or fluid accumulation. Weight loss may become visibly apparent, with the keel bone becoming more prominent and muscle mass diminishing. Feather condition typically deteriorates progressively, and some birds may develop areas of abnormal feather growth or color. Weakness in the legs may occur due to kidney-related calcium and electrolyte imbalances, and some birds develop joint swelling associated with gout.

Symptom progression in renal tubular disease follows a generally predictable pattern, though the rate of progression varies considerably depending on the underlying cause and how quickly treatment is initiated. In acute presentations, symptoms may appear suddenly and progress rapidly over days, while chronic cases may develop insidiously over months to years. Early-stage disease may be characterized primarily by increased thirst and urination, while intermediate stages typically involve weight loss, decreased activity, and declining feather quality. Advanced disease often presents with more severe symptoms including profound weakness, anorexia, neurological signs, and evidence of secondary gout.

Emergency symptoms requiring immediate avian veterinary care include severe lethargy or inability to perch, complete loss of appetite lasting more than 24 hours, significant changes in breathing pattern or rate, blood in the droppings, extreme weakness or collapse, and signs of pain such as hunched posture or reluctance to move. Seizures or other neurological symptoms indicate a critical situation that demands urgent intervention. Sudden swelling of joints, particularly in the feet and legs, may indicate acute gout and requires immediate treatment to prevent severe pain and permanent damage. Birds showing signs of severe dehydration, including sunken eyes and tacky mucous membranes, need emergency fluid therapy. Any sudden worsening of previously stable symptoms should prompt immediate veterinary evaluation.

The initial examination for suspected renal tubular disease begins with a comprehensive physical assessment by an avian veterinarian who will evaluate the bird's overall condition, hydration status, and body weight. The veterinarian will palpate the abdomen to assess kidney size and detect any abnormalities, as enlarged or irregularly shaped kidneys may be detectable in some cases. A thorough history will be obtained, including questions about the bird's diet, housing environment, potential toxin exposures, water intake patterns, and any changes in dropping appearance or behavior. The physical examination also evaluates for signs of secondary complications such as gout, which may manifest as swollen joints or deposits of uric acid crystals visible in the feet or other tissues.

Diagnostic tests for renal tubular disease include both blood work and imaging studies that provide complementary information about kidney function and structure. Blood chemistry panels measuring uric acid, phosphorus, calcium, and electrolyte levels provide important information about kidney function, though it is important to note that uric acid levels in birds may not rise significantly until substantial kidney damage has already occurred. Complete blood counts can reveal anemia, which is common in chronic kidney disease, as well as signs of infection or inflammation. Urinalysis, when possible to obtain, can provide additional information about tubular function. Specialized tests such as plasma protein electrophoresis may help identify underlying infectious or inflammatory conditions contributing to kidney disease.

Differential diagnosis is crucial because many conditions can cause symptoms similar to those of renal tubular disease. Diabetes insipidus, a condition affecting water balance regulation, can cause similar increases in thirst and urination. Liver disease may present with overlapping symptoms and blood chemistry abnormalities. Reproductive disorders in female birds can cause abdominal enlargement and metabolic disturbances that mimic kidney disease. Infectious diseases such as avian chlamydiosis or polyomavirus can affect the kidneys among other organs. The veterinarian must systematically rule out these alternative diagnoses through appropriate testing to ensure accurate identification of the underlying problem and appropriate treatment selection.

Diagnosis confirmation often requires a combination of clinical findings, laboratory results, and imaging studies to establish both the presence and underlying cause of renal tubular disease. Radiographs can reveal kidney enlargement, abnormal shape, or mineralization, while contrast studies may provide additional information about kidney function. Ultrasound examination allows visualization of kidney structure and can help differentiate between various types of kidney disease. In some cases, endoscopy may be recommended to directly visualize the kidneys and obtain biopsy samples for histopathological examination, which provides the most definitive diagnosis and helps identify the specific type of tubular damage present. Once diagnosis is confirmed, staging of disease severity helps guide treatment decisions and establish prognosis.

Emergency and immediate treatment for birds presenting with acute renal tubular disease or severe decompensation of chronic disease focuses on stabilization and correction of life-threatening imbalances. Fluid therapy is the cornerstone of initial treatment, with fluids administered either subcutaneously or intravenously depending on the severity of dehydration and the bird's overall condition. Hospitalization in an incubator or heated environment helps reduce metabolic demands and supports the bird's ability to recover. Oxygen supplementation may be provided if respiratory compromise is present. Emergency treatment of acute gout, if present, includes pain management and specific therapies to reduce uric acid levels. Removal from any suspected toxin exposure is essential if toxicosis is suspected as the underlying cause.

Medical management of renal tubular disease involves a combination of medications tailored to the specific underlying cause and the bird's individual needs. When bacterial infection is identified or suspected, appropriate antibiotics are prescribed, with careful selection of drugs that are not nephrotoxic. Allopurinol may be prescribed to reduce uric acid production in birds with hyperuricemia or gout. Medications to support kidney function and protect remaining tubular cells may be utilized. Phosphate binders may be necessary if blood phosphorus levels are elevated. Fluid therapy, often continued at home through subcutaneous administration, helps maintain hydration and support kidney perfusion. The medication regimen requires careful monitoring and adjustment based on the bird's response and follow-up laboratory results.

Surgical options for renal tubular disease are limited due to the essential nature of kidney tissue and the paired structure of avian kidneys. Surgery may be considered in cases where discrete masses or obstructions are identified that could be removed while preserving functional kidney tissue. Kidney biopsy may be performed surgically or endoscopically to obtain diagnostic samples when the underlying cause remains unclear despite other testing. In rare cases of single kidney tumors, surgical removal may be attempted if the opposite kidney is functional. However, most cases of renal tubular disease are managed medically rather than surgically, as the diffuse nature of tubular damage typically makes surgical intervention inappropriate.

Supportive care plays a central role in the management of renal tubular disease and includes nutritional support, environmental modifications, and ongoing monitoring. Nutritional support may involve feeding assistance, offering highly palatable foods, or providing supplemental feeding through crop tube if the bird is not eating adequately. Environmental temperature should be maintained at the warmer end of the bird's comfort range to reduce metabolic demands. Humidity may need adjustment to prevent excessive water loss through respiration. Clean, fresh water should be available at all times, and water intake should be monitored. Reducing stress through quiet housing and minimal handling during acute illness supports recovery.

Alternative and complementary treatments for renal tubular disease may be considered as adjuncts to conventional veterinary care. Herbal supplements with purported kidney-supportive properties are sometimes recommended, though their efficacy in avian species is not well documented and they should only be used under veterinary supervision. Acupuncture has been utilized in some avian patients to support overall health and potentially improve quality of life. Probiotics may help support gut health and nutrient absorption. Nebulization therapy is not directly beneficial for kidney disease but may help if concurrent respiratory involvement is present. Any alternative therapies should be discussed with the avian veterinarian to ensure they do not interfere with conventional treatment.

Treatment decision factors for renal tubular disease include the severity of kidney damage, the underlying cause, the bird's overall health status, and practical considerations for the owner. The extent of remaining kidney function influences prognosis and determines how aggressively treatment should be pursued. Cost considerations are realistic factors, as long-term management of kidney disease can involve ongoing medication, regular laboratory monitoring, and potential hospitalization during illness episodes. Owner lifestyle factors, including ability to administer medications, provide special diets, and monitor the bird closely, influence the feasibility of various treatment approaches. Expected outcomes should be discussed honestly, with understanding that management rather than cure is typically the goal for significant tubular damage.

Recovery timeline for renal tubular disease varies considerably depending on the underlying cause, extent of damage, and how quickly treatment is initiated. Acute kidney injury from toxin exposure may show improvement within days to weeks if the toxic exposure is eliminated and supportive care is provided promptly, though complete recovery depends on the severity of initial damage. Chronic renal tubular disease typically does not fully resolve but can be stabilized with appropriate management, with improvement in clinical signs often observed over weeks to months of consistent treatment. The recovery process should be viewed as gradual stabilization rather than a return to completely normal kidney function, as damaged tubular tissue has limited capacity for regeneration.

Post-treatment care requirements are ongoing for birds with renal tubular disease and include regular medication administration, dietary management, and environmental maintenance. Medications may need to be given daily, and owners should be trained in proper administration techniques to minimize stress on the bird. Follow-up veterinary appointments are essential for monitoring kidney function through blood tests and adjusting treatment as needed. Weight monitoring at home helps track nutritional status, and owners should keep records of water intake and dropping appearance to identify any changes that might indicate disease progression or improvement. Activity levels should be allowed to normalize gradually as the bird's condition stabilizes.

Prognosis factors for renal tubular disease include the extent of tubular damage at diagnosis, the underlying cause and whether it can be fully addressed, the bird's species and age, and the owner's ability to provide consistent long-term care. Birds diagnosed early with limited tubular damage have the best prognosis, while those with extensive damage at diagnosis face more guarded outcomes. Prognosis is generally better when a specific treatable cause is identified, such as infection or toxin exposure that can be eliminated. Younger birds may have somewhat better regenerative capacity and response to treatment compared to geriatric birds with age-related kidney decline. Consistent adherence to treatment recommendations significantly influences long-term outcomes.

Long-term outlook for birds with renal tubular disease ranges from good to guarded depending on individual circumstances. Many birds with well-managed disease can maintain good quality of life for years, though they require ongoing monitoring and care adjustments. The risk of recurrence or progression is always present, and owners should be prepared for the possibility of episodic illness requiring veterinary intervention. Regular monitoring allows early detection of any decline in kidney function so that treatment can be adjusted accordingly. Return to normal activities is often possible for birds with stable disease, though some activity modifications may be permanently necessary. The human-animal bond can remain strong throughout the management of chronic kidney disease with appropriate support and realistic expectations.

Environmental prevention of renal tubular disease focuses on eliminating potential sources of kidney damage from the bird's living space. Housing should be constructed of safe materials, avoiding galvanized metal that can release zinc and older painted surfaces that may contain lead. Air quality is important, with good ventilation to prevent buildup of fumes from cooking, cleaning products, or other household sources that could affect kidney health. Temperature should be maintained within the appropriate range for the species, and humidity levels should support hydration without promoting excessive moisture that could encourage microbial growth. Regular cleaning of the cage and accessories with bird-safe products prevents buildup of harmful substances and reduces infection risk.

Quarantine protocols are essential for preventing infectious causes of kidney disease when introducing new birds to an existing flock. New birds should be quarantined for a minimum of 30 to 45 days, during which time they should be housed in a completely separate airspace from resident birds. During quarantine, new birds should be examined by an avian veterinarian and undergo appropriate testing for common infectious diseases that can affect the kidneys, including chlamydiosis and viral infections. Only birds that remain healthy throughout quarantine and receive negative test results should be introduced to the main bird area. This approach protects resident birds from potentially nephrotoxic infectious agents.

Dietary prevention involves providing appropriate nutrition that supports kidney health without placing excessive demands on the renal system. A balanced diet formulated for the specific species is fundamental, with appropriate protein levels that meet nutritional needs without providing excess that must be metabolized and excreted by the kidneys. Fresh water should be available at all times and changed at least daily to encourage adequate hydration. Foods known to support kidney health, including fresh vegetables and fruits appropriate for the species, should be included regularly. Supplements, particularly vitamin D3 and calcium, should be provided only as recommended by a veterinarian, as excessive amounts can contribute to kidney damage.

Health maintenance practices for preventing renal tubular disease include regular veterinary care, appropriate health monitoring, and attention to overall wellness. Annual examinations by an avian veterinarian allow for early detection of developing kidney problems through physical examination and screening blood work. Maintaining a healthy weight through appropriate diet and exercise reduces metabolic stress on the kidneys. Prompt treatment of any illness helps prevent secondary kidney involvement that can occur with systemic disease. Avoiding exposure to medications or substances known to be nephrotoxic is essential, and any medications should only be used under veterinary supervision.

Early intervention is crucial for preventing progression of renal tubular disease when early signs develop. Owners should be educated about the early warning signs of kidney disease, including changes in water consumption, urination patterns, and dropping appearance. Any concerns should prompt veterinary consultation rather than waiting to see if symptoms resolve on their own. Screening bloodwork may be recommended for birds at higher risk due to species, age, or family history, allowing detection of subclinical kidney changes before clinical signs develop. Working closely with an avian veterinarian to establish baseline health parameters for each bird enables detection of subtle changes that might indicate developing kidney problems.

Daily management of a bird with renal tubular disease requires attention to several key aspects of care that support kidney function and overall wellbeing. Medication administration should occur at consistent times each day, following veterinary instructions for dosing and technique. Water intake should be monitored and recorded, as changes may indicate fluctuation in kidney function. Fresh water must be available at all times, and some birds benefit from multiple water sources or water delivery methods such as sipper bottles in addition to open dishes. Droppings should be observed daily for changes in the urine, urate, or fecal components that might signal worsening kidney function or the development of secondary problems such as gout.

Home environment modifications can significantly support a bird with renal tubular disease and improve quality of life during long-term management. The cage should be arranged to minimize the need for strenuous climbing, with perches placed at easily accessible heights and food and water dishes positioned for convenient access. Temperature control becomes more important for birds with compromised kidney function, and a supplemental heat source may be beneficial, particularly during cooler months or if the bird shows signs of being chilled. Humidity levels should support hydration without creating an overly damp environment. A quiet location away from high-traffic areas and stressful stimuli helps reduce metabolic demands on the body.

Maintaining quality of life for birds with renal tubular disease involves balancing medical needs with opportunities for normal behavior and enjoyment. While some activity restriction may be necessary during acute illness, stable birds should be encouraged to engage in appropriate activities that provide mental stimulation and physical exercise. Foraging opportunities, toys, and social interaction remain important aspects of daily life. Favorite foods can be offered as treats within dietary guidelines to maintain appetite and interest in eating. Maintaining routines and familiar elements of the environment provides psychological comfort for birds coping with chronic illness.

Monitoring and ongoing care requirements include both home observation and regular veterinary follow-up. Owners should maintain records of daily water intake, dropping appearance, weight when possible, and any behavioral changes or symptoms observed. Regular weigh-ins using a gram scale help detect subtle weight changes that may indicate disease progression or improvement. Follow-up veterinary visits should occur as recommended, typically every few months for stable patients, with blood work to assess kidney function and adjust treatment as needed. Any sudden changes in condition should prompt immediate veterinary contact rather than waiting for the next scheduled appointment.

Caregiver support is an important consideration when managing a bird with chronic renal disease, as the ongoing demands of care can be emotionally and practically challenging. Connecting with other bird owners managing similar conditions through online support groups or local bird clubs can provide valuable emotional support and practical tips. Financial planning for ongoing veterinary care, medications, and special diet items helps reduce stress associated with treatment costs. Learning to recognize the difference between normal fluctuations and genuine emergencies helps caregivers respond appropriately without unnecessary anxiety. Taking breaks and maintaining self-care prevents burnout that could ultimately affect the quality of care provided to the bird.

High-risk species for renal tubular disease include budgerigars, which demonstrate a notable predisposition to kidney problems that appears to have a hereditary component within certain genetic lines. Cockatiels also show elevated rates of kidney disease compared to some other parrot species, with dietary factors often contributing to kidney stress in this species. Amazon parrots, particularly older individuals, frequently develop kidney issues as they age, making regular monitoring especially important in geriatric Amazons. African grey parrots may be predisposed to kidney problems related to their sensitivity to calcium metabolism disorders. The reasons for species differences in susceptibility include genetic factors, typical dietary patterns, and physiological variations in how different species process and excrete metabolic wastes.

Moderate-risk species for renal tubular disease include many commonly kept psittacine birds, with risk increasing based on age, diet, and individual circumstances. Macaws and conures can develop kidney disease, particularly when fed inappropriate diets or exposed to environmental toxins. Lovebirds and parrotlets, while smaller, are not immune to kidney problems and may develop disease related to similar factors as their larger relatives. Softbills and finches may develop kidney issues related to their specific dietary requirements and metabolism. Mixed-species collections may see varying rates of kidney disease depending on the species represented and how individual needs are being met.

Screening recommendations for species at risk include baseline blood chemistry panels during initial veterinary examinations, with periodic monitoring throughout life to track any changes in kidney function parameters. For high-risk species such as budgerigars, annual screening blood work beginning at middle age may help detect early kidney changes before clinical signs develop. Breeders working with lines that have demonstrated kidney problems should consider screening breeding stock and making informed decisions about pairings. When acquiring birds, particularly from species with known kidney susceptibilities, inquiring about family health history can provide valuable information about potential risks. Working with an avian veterinarian to develop an individualized screening schedule based on species, age, and individual risk factors ensures appropriate monitoring without unnecessary testing.

Commonly co-occurring conditions with renal tubular disease include gout, which develops when the kidneys can no longer adequately excrete uric acid, leading to crystal deposition in joints and internal organs. Dehydration often accompanies kidney disease and can both result from and contribute to tubular damage. Anemia is a frequent complication of chronic kidney disease in birds, developing because the kidneys produce hormones involved in red blood cell production. Electrolyte imbalances, particularly involving calcium, phosphorus, and potassium, commonly occur as the damaged tubules lose their ability to properly regulate these essential minerals. Secondary hyperparathyroidism may develop as the body attempts to maintain calcium balance in the face of kidney dysfunction.

Conditions with similar symptoms to renal tubular disease include diabetes insipidus, which causes increased thirst and urination through a different mechanism involving hormone regulation of water balance. Liver disease can produce similar clinical signs and blood chemistry changes, making differentiation important for appropriate treatment. Reproductive disorders in female birds, including chronic egg-laying and egg binding, may cause abdominal enlargement and metabolic disturbances that overlap with kidney disease presentations. Infectious diseases affecting multiple organ systems, such as chlamydiosis, can cause kidney involvement along with other symptoms. Accurate diagnosis is essential because treatment approaches differ significantly between these conditions.

Potential complications of renal tubular disease include acute kidney failure, which may occur if the disease progresses beyond the kidneys' compensatory capacity or if an additional insult occurs in a bird with already compromised kidney function. Articular gout, with painful uric acid crystal deposits in the joints, can severely impact mobility and quality of life. Visceral gout involves uric acid deposits on internal organs and carries a poor prognosis. Malnutrition may develop as birds lose appetite or become unable to properly absorb and utilize nutrients. Bone demineralization can occur due to calcium and phosphorus imbalances. Preventing complications requires consistent management of the underlying kidney disease and prompt attention to any new symptoms that develop.
