Kidney disease is often associated with adults, but kidney disease in children can occur from infancy through adolescence. Some children are born with kidney abnormalities, while others develop kidney disease because of infections, immune-related conditions, genetic disorders or other medical problems.

Early recognition is extremely important because timely treatment may help protect kidney function, support normal growth and reduce the risk of long-term kidney damage.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides evaluation and long-term management of kidney disorders, including conditions that affect children and adolescents.

What Is Kidney Disease in Children?

Kidney disease in children refers to conditions that affect the kidneys' ability to filter blood, regulate fluid balance, maintain electrolyte levels, support normal blood pressure and contribute to healthy growth and development.

Pediatric kidney disease can range from mild urinary abnormalities to severe chronic kidney disease requiring specialized treatment.

Common Causes of Kidney Disease in Children

Several different conditions can affect the kidneys during childhood.

Congenital Kidney Abnormalities

Some children are born with structural kidney or urinary tract abnormalities that affect kidney function.

Examples include:

• Abnormal kidney development

• Blockage in the urinary tract

• Vesicoureteral reflux

• Duplex kidneys

• Other congenital urinary tract abnormalities

Urinary Tract Infections

Repeated or severe urinary infections, particularly kidney infections, can affect kidney health if not appropriately treated.

Nephrotic Syndrome

Nephrotic syndrome is one of the more common kidney disorders seen in children and is characterized by significant protein loss in the urine.

Glomerulonephritis

Inflammation of the kidney's filtering units can occur after infections or because of immune-related conditions.

Genetic Kidney Disorders

Inherited conditions such as polycystic kidney disease and other genetic disorders can affect kidney function.

Systemic Diseases

Certain autoimmune or metabolic disorders can involve the kidneys.

Early Symptoms of Kidney Disease in Children

Many kidney disorders may initially cause subtle symptoms.

Parents should seek medical evaluation if a child develops:

• Swelling around the eyes

• Swelling of the feet or ankles

• Foamy urine

• Blood in the urine

• Reduced urine output

• Frequent urination

• Pain during urination

• Recurrent urinary infections

• Poor growth

• Poor weight gain

• Fatigue

• Pale appearance

• High blood pressure

• Persistent bedwetting after previous dryness in some cases

These symptoms can have many different causes, but they should not be ignored.

Kidney Disease in Infants and Young Children

Kidney disease in infants may present differently from kidney disease in older children.

Possible warning signs include:

• Poor feeding

• Vomiting

• Failure to gain weight

• Persistent fever

• Reduced urine output

• Swelling

• Irritability

• Developmental concerns

Congenital kidney abnormalities are an important consideration in younger children.

Why Kidney Disease Can Affect Growth

Healthy kidneys contribute to normal growth through their effects on nutrition, bone health, hormone production and overall metabolism.

Chronic kidney disease can interfere with:

• Appetite

• Nutrition

• Bone mineral balance

• Growth hormone pathways

• Red blood cell production

This is why growth monitoring is an important part of pediatric kidney care.

How Kidney Disease in Children Is Diagnosed

Diagnosis usually involves a combination of clinical evaluation and investigations.

Medical History and Examination

The doctor may ask about:

• Urinary symptoms

• Swelling

• Growth

• Blood pressure

• Birth history

• Family history of kidney disease

• Recurrent infections

Urine Tests

Urine testing may evaluate:

• Protein

• Albumin

• Blood

• Infection

• Concentration ability

• Other abnormalities

Blood Tests

Tests may include:

• Serum creatinine

• eGFR estimation

• Electrolytes

• Albumin

• Blood counts

• Other disease-specific tests

Kidney Ultrasound

Ultrasound is commonly used to evaluate kidney size, structure and urinary tract abnormalities.

Additional tests may be recommended depending on the suspected diagnosis.

Nephrotic Syndrome in Children

One of the most important pediatric kidney disorders is nephrotic syndrome.

Children may develop:

• Significant swelling

• Protein loss in urine

• Low blood protein levels

• Increased risk of infection and blood clots in some cases

Many children respond well to appropriate medical treatment, but regular follow-up is essential.

Urinary Tract Infections and Kidney Damage

Recurrent urinary infections, particularly those involving the kidneys, may increase the risk of kidney scarring in some children.

Evaluation may be recommended when a child has:

• Repeated urinary infections

• Fever with urinary infection

• Poor urine flow

• Abnormal ultrasound findings

• Growth concerns

Treating infections promptly is important.

Can Children Develop Chronic Kidney Disease?

Yes. Chronic kidney disease (CKD) can occur in children.

Common causes include:

• Congenital kidney abnormalities

• Reflux nephropathy

• Glomerular diseases

• Genetic kidney disorders

• Obstructive uropathy

• Other chronic kidney conditions

Early nephrology care may help slow progression and manage complications.

Treatment of Kidney Disease in Children

Treatment depends entirely on the underlying cause.

Possible approaches include:

Treatment of Infection

Appropriate antibiotics may be required for urinary tract or kidney infections.

Blood Pressure Control

Hypertension can contribute to kidney damage and requires careful management.

Management of Proteinuria

Certain medicines may be used to reduce protein loss in urine in selected conditions.

Immunosuppressive Therapy

Some immune-mediated kidney diseases require specialized treatment.

Surgical Management

Congenital urinary tract abnormalities or obstruction may require pediatric urological intervention.

Nutrition and Growth Support

Children with CKD may require individualized nutritional management.

Can Kidney Disease in Children Be Cured?

The answer depends on the diagnosis.

Some kidney problems may resolve completely with treatment, while others require long-term monitoring or ongoing therapy.

The goal is often to preserve kidney function, support normal growth and prevent complications.

Preventing Kidney Problems in Children

Parents can help protect kidney health by:

• Seeking prompt treatment for urinary infections

• Ensuring adequate hydration during illness

• Avoiding unnecessary medications

• Following treatment plans for known kidney conditions

• Monitoring blood pressure when recommended

• Attending follow-up appointments

• Reporting swelling or urinary changes early

When Should a Child See a Nephrologist?

Specialist kidney evaluation is recommended if a child has:

• Persistent protein in urine

• Blood in urine

• Reduced kidney function

• Congenital kidney abnormalities

• Recurrent kidney infections

• Nephrotic syndrome

• High blood pressure

• Poor growth with kidney abnormalities

• Family history of inherited kidney disease

• Recurrent unexplained swelling

Early specialist assessment can be important for long-term kidney protection.
