Important: This screening tool provides a preliminary assessment of your child's kidney health and is not a diagnosis. Results should be discussed with a qualified pediatric nephrologist. If your child is experiencing severe symptoms (bloody urine, severe swelling, inability to urinate), seek emergency medical care immediately. This tool is designed by Dr. Anil Prasad Bhatt for educational and screening purposes only.

Common Pediatric Kidney Conditions

Nephrotic Syndrome

A condition where the kidneys leak large amounts of protein into the urine. Signs include puffy eyes in the morning, swollen ankles, and foamy urine. Most common in children ages 2-6. Often responds well to steroid treatment.

Ages 2-6Treatable

Urinary Tract Infection (UTI)

Bacterial infection in the urinary system. In infants, the only sign may be fever. Older children may have pain during urination, frequent urination, or abdominal pain. Recurrent UTIs need investigation for underlying causes like VUR.

All AgesCurable

Vesicoureteral Reflux (VUR)

Urine flows backward from the bladder toward the kidneys. Graded I-V by severity. Many children outgrow lower grades. Higher grades may need surgery. Important to diagnose early to prevent kidney scarring from recurrent infections.

Infants/ToddlersMay Outgrow

Hydronephrosis

Swelling of one or both kidneys caused by urine backup. Often detected on prenatal ultrasound. Mild cases may resolve on their own. Severe cases can damage the kidney and may require surgical correction to relieve the obstruction.

PrenatalMonitored

Hemolytic Uremic Syndrome (HUS)

A serious condition often triggered by E. coli infection, causing destruction of red blood cells and acute kidney injury. Symptoms include bloody diarrhea followed by decreased urination, pallor, and bruising. Requires urgent hospitalization.

EmergencyAges 1-10

IgA Nephropathy

An immune condition where IgA antibodies deposit in the kidneys. Often presents as dark or cola-colored urine during or after a cold or throat infection. Most common glomerulonephritis in older children and adolescents. Needs long-term monitoring.

School AgeChronic

Alport Syndrome

A genetic condition affecting the kidneys, ears, and eyes. Caused by mutations in collagen genes. Presents with blood in urine (often microscopic), hearing loss, and eye changes. More severe in males (X-linked form). Leads to progressive kidney disease.

GeneticProgressive

CAKUT

Congenital Anomalies of the Kidney and Urinary Tract. The most common cause of CKD in children. Includes absent kidneys, ectopic kidneys, duplex systems, and urethral valves. Often detected prenatally or in infancy. Management depends on specific anomaly and severity.

When to See a Pediatric Nephrologist

Consult a specialist if your child has any of the following. Early detection can prevent permanent kidney damage.

Blood visible in urine (pink, red, or cola-colored)
Persistent protein in urine (foamy urine or positive dipstick)
Facial or body swelling, especially around the eyes in the morning
High blood pressure detected at any age
Recurrent UTIs (3+ in girls, 2+ in boys)
Abnormal kidney ultrasound findings
Failure to thrive or poor growth below 3rd percentile
Family history of genetic kidney disease (PKD, Alport, etc.)
Bedwetting after age 7 that is getting worse
Abnormal blood tests (elevated creatinine, low eGFR)
Kidney stones or flank pain in a child
Unexplained anemia that does not respond to iron supplementation

Growth Chart Concern Indicators

On Track

Growing along their curve (10th-90th percentile), consistent weight gain, normal height velocity

⚠️

Watch Zone

Crossing percentile lines downward, below 10th percentile, plateauing growth, height falling behind weight

🚨

Needs Evaluation

Below 3rd percentile, significant drop across 2+ percentile lines, not gaining weight for 3+ months

Vaccination Considerations for Children with Kidney Disease

Recommended Vaccines

All routine childhood vaccines should be given on schedule. Pneumococcal (PCV13 + PPSV23), annual influenza vaccine, and Hepatitis B are especially important for kidney patients.

Timing Matters

If your child is on immunosuppressants (for nephrotic syndrome or transplant), live vaccines (MMR, varicella) should be given before starting treatment or during remission when off medications.

Caution with Live Vaccines

Children on high-dose steroids, rituximab, or other immunosuppressants should NOT receive live vaccines until cleared by their nephrologist. Discuss timing with your doctor.

Parent Tips for Kidney Health

Hydration

  • Encourage regular water intake throughout the day
  • Limit sugary drinks and sodas
  • Watch for signs of dehydration (dark urine, dry lips)
  • Increase fluids during hot weather and physical activity
  • Infants: breast milk or formula provides adequate hydration

Diet

  • Offer a balanced diet rich in fruits and vegetables
  • Limit processed foods and excess salt
  • Ensure adequate calcium for growing bones
  • Avoid excessive protein (consult doctor for CKD children)
  • Monitor potassium and phosphorus if advised by nephrologist

UTI Prevention

  • Teach proper wiping technique (front to back for girls)
  • Encourage regular bathroom breaks (no holding urine)
  • Avoid bubble baths and harsh soaps in genital area
  • Cotton underwear is preferred
  • Treat constipation promptly (it contributes to UTIs)

When to Worry

  • Any visible blood in urine - see a doctor promptly
  • Sudden swelling of face, hands, or feet
  • Persistent bedwetting after age 7 (worsening)
  • Unexplained fatigue, pallor, or poor appetite
  • Failure to gain weight or grow as expected
