  • Hematuria (blood in the urine)
  • Proteinuria (protein in the urine)
  • Congenital kidney anomalies
  • Nephrotic syndrome
  • Acute glomerulonephritis
  • Acute kidney injury
  • Chronic kidney disease
  • Hypertension (high blood pressure)
  • Kidney stone disease
  • Electrolyte disorders
  • Urinary tract infections
  • Vesicoureteral reflux
  • Enuresis (bed wetting) and voiding dysfunction
  • Renal tubular acidosis and other tubular diseases

For children with end-stage kidney disease, we offer renal replacement therapies such as:

  • Hemodialysis
  • Peritoneal dialysis
  • Kidney transplantation

Services & Programs

High Blood Pressure Program

Our Division is the main referral center for children with hypertension. We use ambulatory blood pressure monitoring for diagnosis and follow up of children with hypertension. 

End Stage Renal Disease

We offer hemodialysis and peritoneal dialysis for children with end stage renal disease. We have a trained and dedicated nursing staff and the ability to dialyze small children.  In addition, we have a dedicated peritoneal dialysis nurse who trains and assists our pediatric patients and their families.

Kidney Transplantation

As part of the Weill Cornell Medicine Transplant Program, our team coordinates and provides pre-transplant work up, transplant care, and follow-up care for children who require kidney transplantation.  We partner with Rogosin Institute, the oldest and largest kidney transplant center in the Tri-State area.

Growth Failure Program

Our team has special expertise in the management of children with growth failure resulting from chronic kidney disease. We are particularly interested in why some children with kidney failure do not grow and how recombinant human growth hormone allows them to grow more normally. We are examining the role of cytokines and Leptin in the growth process and their correlation with body composition and growth parameters. 

Diagnosis & Treatment


Kidney biopsies are routinely performed in children of all ages for diagnostic purposes. Biopsies are performed at our outpatient sedation unit with ultrasound guidance and the support of Weill Cornell Medicine’s Pediatric Anesthesiology division.

Blood Pressure Monitoring

Twenty-four hour ambulatory blood pressure monitoring is available to evaluate children and adolescents with elevated blood pressure readings. It is an invaluable tool in distinguishing those children with so-called "white coat" hypertension form those with an elevation of their blood pressure load.
