Kidney problems can sometimes begin before a child is born. These conditions are broadly described as congenital kidney diseases or congenital kidney abnormalities. They may involve the size, shape, structure or development of one or both kidneys and can range from mild abnormalities that require only monitoring to serious conditions that affect kidney function.

Some congenital kidney conditions are discovered during pregnancy, while others are identified during childhood or even adulthood after symptoms or abnormal kidney tests appear.

Early diagnosis and appropriate follow-up are important because certain congenital abnormalities can increase the risk of urinary infections, high blood pressure, kidney stones, protein in the urine and chronic kidney disease.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides comprehensive evaluation and long-term management for kidney disorders and reduced kidney function.

What Is Congenital Kidney Disease?

Congenital kidney disease refers to a kidney abnormality that is present at birth.

The condition may affect:

• Kidney development

• Kidney size

• Kidney position

• Kidney structure

• Urinary drainage

• The number of kidneys

• The connection between the kidneys and urinary tract

Not every congenital kidney abnormality causes immediate symptoms or significant kidney dysfunction.

Common Types of Congenital Kidney Abnormalities

Renal Agenesis

Renal agenesis occurs when one or both kidneys fail to develop properly.

When only one kidney is absent, the other kidney may sometimes compensate and provide adequate kidney function.

Renal Hypoplasia

A hypoplastic kidney is smaller than expected because it has not developed normally.

The impact depends on whether one or both kidneys are affected.

Duplex Kidney

A duplex kidney occurs when part of the urinary collecting system develops as a duplicated structure.

Some people have no symptoms, while others may experience urinary infections or urinary drainage problems.

Horseshoe Kidney

In horseshoe kidney, the lower portions of the kidneys are connected.

Many individuals have normal kidney function, but some may have an increased risk of:

• Kidney stones

• Urinary infections

• Urinary obstruction

Ectopic Kidney

An ectopic kidney is located somewhere other than its usual position.

For example, it may remain lower in the abdomen or pelvis.

Congenital Hydronephrosis

Abnormal urinary drainage can cause urine to accumulate within the kidney, resulting in hydronephrosis.

Congenital Cystic Kidney Disorders

Some cystic kidney conditions can have genetic or developmental causes and may affect kidney function over time.

What Causes Congenital Kidney Disease?

Congenital kidney abnormalities can develop because of:

• Genetic changes

• Abnormal fetal kidney development

• Inherited conditions

• Developmental abnormalities

• Problems affecting urinary tract formation

Some congenital kidney conditions occur as part of a broader genetic syndrome.

In many cases, the exact cause is not immediately apparent.

Symptoms of Congenital Kidney Disease

Symptoms vary considerably.

Some people have no symptoms at all.

Possible symptoms include:

• Recurrent urinary tract infections

• Abdominal or flank discomfort

• Blood in the urine

• Protein in the urine

• Kidney stones

• High blood pressure

• Poor growth in children

• Swelling

• Changes in urination

• Abnormal kidney function tests

The absence of symptoms does not necessarily mean that kidney function is normal.

Congenital Kidney Disease in Babies and Children

Some abnormalities are detected during pregnancy through prenatal ultrasound.

After birth, doctors may monitor:

• Kidney size

• Urine output

• Blood pressure

• Growth

• Kidney function

• Urinary infections

Children with significant abnormalities may require ongoing pediatric nephrology or multidisciplinary care.

Can Congenital Kidney Disease Be Detected During Pregnancy?

Yes, some structural abnormalities can be identified during prenatal ultrasound.

However, not every congenital kidney disorder is visible before birth.

Additional monitoring may be recommended depending on the ultrasound findings and family history.

How Is Congenital Kidney Disease Diagnosed?

Diagnosis depends on the suspected abnormality.

Ultrasound

Kidney ultrasound is commonly used to evaluate:

• Kidney size

• Position

• Shape

• Cysts

• Hydronephrosis

• Urinary tract abnormalities

Blood Tests

Tests may include:

• Serum creatinine

• eGFR

• Electrolytes

• Hemoglobin

Urine Tests

Urinalysis can identify:

• Protein

• Blood

• Infection

• Other abnormalities

Additional Imaging

Depending on the condition, doctors may recommend specialized imaging to assess urinary drainage and kidney anatomy.

Genetic Testing

Genetic evaluation may be considered when the condition appears inherited or occurs with other abnormalities.

Does Congenital Kidney Disease Always Cause Kidney Failure?

No.

The outcome depends on the type and severity of the abnormality.

Some individuals with a single normally functioning kidney maintain good kidney function throughout life.

Others may develop progressive kidney disease because of:

• Abnormal kidney structure

• Recurrent infections

• Urinary obstruction

• Proteinuria

• Associated genetic disease

Regular monitoring helps identify problems early.

Congenital Kidney Disease and High Blood Pressure

People with congenital kidney abnormalities may have an increased risk of hypertension.

High blood pressure itself can further damage kidney function.

Therefore, regular blood pressure monitoring is an important part of long-term care.

Congenital Kidney Disease and Kidney Stones

Certain structural abnormalities can increase the likelihood of kidney stones.

If stones develop repeatedly, a specialist may recommend:

• Imaging

• Stone analysis

• Urine testing

• Metabolic evaluation

• Dietary recommendations

Treatment for Congenital Kidney Disease

There is no single treatment because congenital kidney disease includes many different conditions.

Treatment may involve:

Observation and Regular Monitoring

Mild abnormalities may only require periodic evaluation.

Blood Pressure Management

Appropriate treatment can help protect kidney function.

Treatment of Urinary Infections

Recurrent infections require evaluation for an underlying urinary tract abnormality.

Management of Urinary Obstruction

Some structural problems may require specialized urological treatment.

Kidney Stone Management

Stones may require medication, dietary measures or procedures depending on their size and location.

Treatment of Progressive Kidney Disease

Patients who develop CKD may require long-term nephrology care.

Living With One Kidney

People born with one functioning kidney can often lead active, healthy lives.

However, regular monitoring may be recommended for:

• Blood pressure

• Kidney function

• Urine protein

• Overall kidney health

Avoiding unnecessary kidney injury is particularly important.

Can Congenital Kidney Disease Be Prevented?

Most congenital structural kidney abnormalities cannot be completely prevented because they develop during fetal development.

However, early detection can help prevent complications.

Pregnancy care, appropriate prenatal screening and medical evaluation of infants with abnormal ultrasound findings are important.

When Should You Consult a Nephrologist?

A nephrology consultation may be appropriate if you or your child has:

• A congenital kidney abnormality detected on ultrasound

• One functioning kidney

• Recurrent urinary infections

• Protein in the urine

• Blood in the urine

• High blood pressure

• Abnormal creatinine

• Reduced eGFR

• Recurrent kidney stones

• Family history of inherited kidney disease

Frequently Asked Questions

Is congenital kidney disease hereditary?

Some congenital kidney conditions are inherited, while others occur because of developmental abnormalities without a clear family history.

Can a person live normally with one kidney?

Many people with one healthy functioning kidney can live normal, active lives, although periodic kidney and blood pressure monitoring may be recommended.

Can congenital kidney disease be cured?

Some structural abnormalities can be corrected or managed, while others require lifelong monitoring rather than a cure.

Can congenital kidney disease cause CKD?

Yes. Certain congenital kidney abnormalities can increase the risk of chronic kidney disease, particularly when both kidneys are affected or complications develop.

Can congenital kidney disease be diagnosed in adults?

Yes. Some congenital abnormalities remain unnoticed until adulthood and are discovered during imaging or investigation of urinary or kidney problems.

Conclusion

Congenital kidney disease includes a wide range of kidney and urinary tract abnormalities that are present from birth. Some cause few or no problems, while others can affect kidney function and increase the risk of hypertension, infections, stones or chronic kidney disease.

Early diagnosis, appropriate imaging and regular monitoring can help identify complications and protect kidney function over the long term.
