Kidney problems can affect children of different ages, from newborns and infants to teenagers.

Some kidney and urinary conditions are discovered before birth or during routine examinations, while others become noticeable because of symptoms such as swelling, repeated urinary infections, changes in urine, high blood pressure, poor growth or abnormal blood-test results.

A pediatric nephrologist is a doctor who specializes in kidney diseases in children. Pediatric nephrologists evaluate conditions affecting kidney function, urine abnormalities, blood pressure and several inherited or acquired kidney disorders.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist kidney evaluation and management. When a child requires age-specific pediatric nephrology or surgical pediatric urology care, appropriate specialist referral or coordination may be recommended.

Why Are Children's Kidney Problems Different?

Children are still growing and developing.

A kidney condition can therefore affect more than filtration alone. Depending on the disease, it may also influence:

• Blood pressure

• Growth

• Nutrition

• Bone and mineral health

• Development

• Urinary function

• School and daily activities

Pediatric kidney specialists are trained to consider these age-specific needs when evaluating children with kidney disease.

A child's symptoms may also be different from those of an adult, and some kidney diseases produce very few symptoms in their early stages.

Common Reasons a Child May Need Kidney Evaluation

A child may benefit from kidney assessment when there is:

Protein in the Urine

Proteinuria can be a sign of kidney disease, particularly when it persists or occurs together with other abnormalities.

Significant protein loss can sometimes cause swelling around the eyes, legs, abdomen or other parts of the body.

Blood in the Urine

Pink, red or cola-colored urine may indicate blood in the urinary tract.

Blood in urine has several possible causes and should be evaluated rather than automatically attributed to a kidney disease.

Recurrent Urinary Tract Infections

Repeated UTIs, particularly infections associated with fever, may require assessment for urinary tract abnormalities or conditions such as vesicoureteral reflux.

Some children with recurrent urinary infections may need coordinated care from a pediatric nephrologist and pediatric urologist.

High Blood Pressure

Persistent hypertension in a child can sometimes be associated with kidney disease.

Blood pressure assessment is therefore an important part of evaluating children who may have kidney problems.

Abnormal Creatinine or Reduced Kidney Function

An abnormal kidney-function test may require further investigation to determine whether the change is temporary or related to an underlying kidney disorder.

Swelling Around the Eyes or Legs

Edema can occur with certain kidney diseases, particularly conditions involving significant protein loss.

Morning puffiness around the eyes can be an important clue in some childhood kidney conditions.

Kidney Stones

Children can develop kidney stones and may require evaluation of the underlying cause, especially when stones recur.

Abnormal Kidney Ultrasound

An ultrasound may identify:

• Kidney enlargement

• Structural abnormalities

• Cysts

• Hydronephrosis

• Changes in kidney size

• Other urinary tract abnormalities

An abnormal scan does not necessarily mean that the child has permanent kidney damage, but specialist interpretation may be appropriate.

Kidney Conditions Seen in Children

Childhood kidney disease can have many causes.

Congenital Kidney and Urinary Tract Abnormalities

Some children are born with structural abnormalities involving the kidneys, ureters, bladder or urinary tract.

These may be detected during pregnancy or later in childhood.

Nephrotic Syndrome

Nephrotic syndrome can cause substantial protein loss in urine and swelling.

In children, swelling around the eyes, legs or abdomen may be one of the first noticeable signs.

Glomerular Diseases

Conditions affecting the kidney's filtering units may produce:

• Proteinuria

• Hematuria

• High blood pressure

• Reduced kidney function

• Swelling

Some glomerular diseases require detailed blood, urine and occasionally biopsy-based evaluation.

Chronic Kidney Disease

CKD in children can result from congenital abnormalities, hereditary diseases, urinary tract problems, glomerular disorders and other conditions.

Early CKD may produce few symptoms, making appropriate follow-up important.

Acute Kidney Injury

Acute kidney injury is a sudden reduction in kidney function.

It can occur with severe illness, dehydration, infection, urinary obstruction or other medical conditions. Some children recover kidney function after the underlying cause is treated, although serious AKI can have longer-term consequences.

Inherited Kidney Disorders

Some kidney diseases run in families.

Examples include certain forms of:

• Polycystic kidney disease

• Alport syndrome

• Cystinosis

• Other inherited kidney disorders

Genetic evaluation may be considered when the medical history suggests an inherited condition.

Signs That a Child's Kidneys May Need Checking

Parents should discuss persistent or unexplained symptoms with the child's healthcare professional.

Potential warning signs include:

• Puffy eyes, especially repeatedly

• Swelling of feet or legs

• Foamy urine

• Pink, red or dark urine

• Reduced or unusually frequent urination

• New bedwetting after previously being dry

• Recurrent fever-associated UTIs

• Persistent high blood pressure

• Unexplained fatigue

• Poor appetite

• Nausea or vomiting

• Poor growth

• Recurrent flank or abdominal pain

• Kidney stones

• Abnormal kidney-function tests

These symptoms do not automatically mean kidney disease is present. However, several of them are recognized features that can warrant kidney evaluation in children.

What Tests Does a Child Kidney Specialist Use?

The investigation depends on the child's age, symptoms and suspected condition.

Urine Examination

Urine testing can identify:

• Protein

• Blood

• Signs of infection

• Other abnormalities

Persistent proteinuria or hematuria may require further investigation.

Blood Tests

Depending on the situation, testing may include:

• Creatinine

• Kidney-function assessment

• Electrolytes

• Blood count

• Other disease-specific tests

Kidney function in children needs to be interpreted using pediatric-appropriate methods rather than simply applying adult assumptions.

Blood Pressure Measurement

Blood pressure should be assessed appropriately for the child's age and size.

Persistent hypertension can be an important clue to kidney disease.

Ultrasound and Other Imaging

Imaging may be used to evaluate kidney size, structure, obstruction, cysts or urinary tract abnormalities.

Kidney Biopsy

A biopsy is not required for every child.

In selected cases, examining kidney tissue can help identify the type and severity of kidney disease and guide treatment.

Genetic Testing

Genetic testing may be considered when the child's history, examination or family history suggests an inherited kidney disorder.

Pediatric Nephrologist or Pediatric Urologist: Which Doctor Does a Child Need?

The appropriate specialist depends on the problem.

A pediatric nephrologist focuses on medical kidney conditions, including kidney-function abnormalities, proteinuria, hematuria, hypertension, inherited kidney disease and kidney failure.

A pediatric urologist specializes in surgical and structural conditions involving the urinary tract. This can include certain urinary obstructions, vesicoureteral reflux, urinary tract reconstruction and surgical management of some kidney stones.

Some children need both specialists.

For example, a child with urinary obstruction may require kidney-function monitoring by a nephrologist and correction of the structural problem by a pediatric urologist.

Does Every Child With a Kidney Problem Need Dialysis?

No.

Dialysis is reserved for selected situations in which kidney function is severely impaired and medical treatment cannot adequately control complications.

Some children with acute kidney injury may require temporary dialysis while their kidneys recover. Children with advanced chronic kidney failure may require longer-term kidney replacement therapy, including dialysis or transplantation.

A dialysis decision is based on the child's complete clinical condition rather than one laboratory number.

Can Childhood Kidney Disease Be Treated?

Treatment depends entirely on the diagnosis.

Management may involve:

• Medicines

• Treatment of infection

• Blood-pressure management

• Treatment to reduce protein loss

• Management of electrolyte abnormalities

• Dietary support

• Treatment of urinary obstruction

• Surgical care when required

• Dialysis in selected cases

• Kidney transplantation for appropriate children with kidney failure

The objective may be to cure a reversible problem, control an ongoing disease, prevent complications or preserve kidney function for as long as possible.

Why Early Kidney Evaluation Matters

Some childhood kidney conditions can progress without obvious symptoms.

Early identification may allow doctors to:

• Find the underlying cause

• Monitor kidney function

• Control blood pressure

• Detect proteinuria

• Treat infections or obstruction

• Manage complications

• Support normal growth and development

• Plan long-term care when necessary

NIDDK guidance identifies findings such as proteinuria, persistent hypertension, decreased eGFR, urinary stones, recurrent pyelonephritis and certain urinary abnormalities as reasons for pediatric nephrology referral.

How Parents Can Support a Child With Kidney Disease

Parents and caregivers play an important role in long-term kidney care.

Depending on the child's diagnosis, this may include:

• Giving prescribed medicines on schedule

• Attending follow-up appointments

• Monitoring urine or blood pressure when instructed

• Following the child's individualized dietary plan

• Reporting new swelling or changes in urine

• Avoiding unapproved supplements or medicines

• Keeping recommended vaccinations and routine pediatric care up to date

• Informing doctors about previous kidney problems

Children with kidney disease should not be placed on restrictive diets without professional advice because adequate nutrition is essential for growth.

When Should a Child Be Seen Urgently?

Seek prompt medical attention if a child develops:

• Very little or no urine

• Severe breathing difficulty

• Rapidly increasing swelling

• Severe dehydration

• Persistent vomiting

• Severe flank or abdominal pain

• High fever with suspected urinary infection

• Blood in urine with significant illness

• Confusion or unusual drowsiness

• Rapid deterioration in overall condition

A child with suspected acute kidney injury, severe infection or urinary obstruction may require urgent assessment.

Frequently Asked Questions

What does a child kidney specialist do?

A pediatric nephrologist diagnoses and manages medical kidney problems in children, including kidney-function abnormalities, proteinuria, hematuria, hypertension, inherited kidney disorders and kidney failure.

When should my child see a kidney specialist?

Evaluation may be appropriate for persistent protein in urine, blood in urine with other abnormalities, sustained high blood pressure, reduced kidney function, recurrent kidney infections, kidney stones, swelling or suspected inherited kidney disease.

Can children develop chronic kidney disease?

Yes. Children can develop CKD from congenital urinary tract abnormalities, hereditary diseases, glomerular disorders, recurrent urinary problems and other causes.

Is swelling around a child's eyes related to kidney disease?

It can be. Puffiness around the eyes, particularly when associated with proteinuria, can occur in conditions such as nephrotic syndrome. However, swelling around the eyes has other possible causes and requires appropriate evaluation.

Does a child with kidney disease need a special diet?

Some children require dietary adjustments, but the diet should be individualized according to kidney function, age, growth, laboratory results and diagnosis. Parents should not introduce major dietary restrictions without professional guidance.

Can kidney disease in children be cured?

Some childhood kidney problems are reversible or treatable, while chronic kidney diseases may require long-term management. Treatment depends on the underlying cause and severity.

Can kidney disease affect a child's growth?

Yes. Certain chronic kidney conditions can affect growth and nutrition, which is why monitoring growth and development is an important part of pediatric kidney care.

Is a pediatric nephrologist different from a urologist?

Yes. Pediatric nephrologists primarily manage medical kidney conditions, while pediatric urologists focus on surgical and structural urinary-tract problems. Some children require care from both specialists.

Conclusion

Finding the right child kidney specialist in Mumbai is important when a child has persistent urinary abnormalities, swelling, high blood pressure, recurrent urinary infections, kidney stones, abnormal kidney-function tests or a suspected inherited kidney condition.

Children's kidney problems can have many different causes, and early disease may not always produce obvious symptoms. Appropriate urine testing, blood tests, blood-pressure monitoring and imaging can help identify problems and determine whether specialist care is required.

A pediatric nephrologist focuses on medical kidney disease, while a pediatric urologist manages many structural and surgical urinary conditions. The two specialties may work together when necessary.
