Frequently Asked Questions

A Pediatric Nephrologist is a pediatrician who has completed specialized subspecialty fellowship training dedicated exclusively to the diagnosis, treatment, and long-term management of kidney and urinary conditions in children, from newborns through late adolescence. Dr. Nitish Kumar completed his fellowship at the Institute of Medical Sciences, Banaras Hindu University (IMS-BHU).

A child should be evaluated if they present with facial or ankle swelling (edema), blood or protein detected in urine, recurrent urinary infections, persistent high blood pressure, hydronephrosis on ultrasound, kidney stones, elevated blood creatinine, or poor physical growth with suspected renal involvement.

A pediatric nephrologist is a medical specialist who evaluates kidney function, filtering disorders (like nephrotic syndrome and glomerulonephritis), high blood pressure, and medical kidney management. A pediatric urologist is a surgical specialist who operates on structural blockages, bladder defects, or anatomical anomalies. Nephrologists and urologists frequently collaborate closely to care for children.

Periorbital puffiness (swelling around eyes) is frequently mistaken for an allergy. However, when it persists through the morning and is followed by ankle or belly swelling, it is a hallmark sign of Nephrotic Syndrome. In this condition, the kidneys leak large amounts of protein into the urine, resulting in low blood protein and fluid retention. A simple spot urine test can readily check for protein.

No. Benign or transient proteinuria can occur temporarily during high fevers, intense physical exercise, or in tall adolescents who leak protein only when upright (orthostatic proteinuria). However, if protein is found persistently in early morning urine samples, a pediatric nephrology evaluation is essential.

Hematuria (blood in urine) can be visible (red or cola-brown) or microscopic (detected only by dipstick/lab test). Common causes in children include urinary tract infections, hypercalciuria (excess calcium in urine), post-streptococcal glomerulonephritis (following throat or skin infections), or minor trauma. Specialist assessment identifies the source and ensures proper management.

Recurrent UTIs in children may occur due to underlying structural issues such as Vesicoureteral Reflux (VUR, where urine flows back toward the kidneys), hydronephrosis, or bladder and bowel dysfunction (severe constipation or infrequent voiding). An ultrasound and imaging evaluation help find the cause and protect renal tissue from scarring.

Please bring all existing medical records, including urine routine and culture reports, blood tests (creatinine, urea, electrolytes, complete blood count), previous ultrasound KUB reports/films, referral notes from your child's pediatrician, and any daily medication bottles or doses.

No. The vast majority of children evaluated for common conditions like initial Nephrotic Syndrome, UTIs, and mild proteinuria do not require a kidney biopsy. Biopsies are reserved strictly for atypical, steroid-resistant, or complex glomerulonephritis where tissue diagnosis directs critical treatment choices.

In many cases, treating the underlying primary cause (such as relieving renal artery narrowing, treating kidney inflammation, or adopting dietary adjustments) can resolve or significantly reduce childhood hypertension. Early identification is key to protecting long-term cardiovascular health.
