    Overview For children with kidney disease and disorders, the Division of Pediatric Nephrology at Stony Brook Children's offers the most advanced treatment available in Suffolk County. Not only is it the only Suffolk County hospital to perform renal transplants for children, it also is home to one of the largest pediatric nephrology programs on Long Island, seeing approximately 1,400 patients annually.

    Our Team Team members include physicians, a nurse practitioner, a dialysis nurse, and other medical professionals with pediatric nephrology expertise. The team works closely with other pediatric specialty departments at Stony Brook, in particular pediatric surgery, pediatric urology, and transplantation services, to provide state-of-the-art, compassionate and family-centered care.

    Services The Division of Pediatric Nephrology has the capabilities to diagnose, treat and manage a wide range of kidney disorders including chronic conditions.

     

    Diagnostics.

    • Ambulatory blood pressure monitoring. This helps diagnose children with pre-hypertension who may be at higher risk for kidney disease.
    • Kidney biopsies. A minimally invasive, same day procedure, it is performed in Stony Brook's Pediatric Intensive Care Unit (PICU) under sedation.

    Transplants. More than 70 adult and pediatric kidney transplants are performed at Stony Brook Medicine annually with excellent immediate surgical and long-term results. Most transplant recipients can expect to lead normal, healthy lives after surgery. At Stony Brook, the success rate of the new kidney function is 92% after one year.

    Treatment for Chronic and Acute Conditions. For chronic and acute kidney conditions, including nephritis, nephrosis and nephrotic syndrome, renal artery stenosis and renal failure, Stony Brook offers a number of options.

    • Outpatient hemodialysis. A process for removing waste products and water from the blood when the kidney is no longer able to perform its functions. Routine dialysis is typically done on an outpatient basis.
    • In-house acute hemodialysis. This is dialysis performed in the hospital in cases where the child may need additional medical support.
    • Peritoneal dialysis. A treatment for severe chronic kidney failure that involves the surgical implantation of a catheter into the patient's abdomen to cleanse the blood. This is used as an alternative to hemodialysis.
    • Hemofiltration. A renal replacement therapy similar to hemodialysis that is performed in the Pediatric Intensive Care Unit for patients with acute renal failure.

    Research and Education As Suffolk County's only academic medical center, Stony Brook is committed to training the next generation of physicians. Six to 12 residents a year rotate through the Division of Pediatric Nephrology, not only gaining valuable experience in state-of-the-art medicine, but also continually infusing the program with the latest ideas and approaches. 

    On the research front, Stony Brook participates in numerous studies, allowing patients who qualify access to the novel therapies and approaches only available in clinical trials. Currently, the department is involved in a multi-center, seven-year trial funded by the NIH on nephrotic syndrome. It also is part of the North American Pediatric Renal Transplant Corporative Study (NAPTRCS), which is creating a North American database on patients with kidney disease, patients undergoing dialysis, and patients who have received transplants.

    Advances and Recognitions
    Back to top

     

    Definitions Hypertension - Also known as high blood pressure, hypertension occurs when the force of the blood flow is too high, stretching the tissue that makes up the walls of arteries beyond its healthy limit. This can often lead to heart attack and heart failure, stroke, kidney failure, and other health consequences.

    Dialysis - A process for removing waste products and water from the blood when the kidney is no longer able to perform its functions.

    Hematuria - The presence of blood in the urine. Blood that you can see is called gross hematuria. Urinary blood that's visible only under a microscope is known as microscopic hematuria and is uncovered after a urine test.

    Hydronephrosis - Typically occurring with another disease, hydronephrosis is a condition in which the kidney swells, due to a backup of urine.

    Kidney cysts - A cyst is a closed pocket or pouch of tissue filled with fluid or air that can form anywhere in the body. Cysts that form on the kidneys usually contain fluid. One or more cysts may develop on small tubes in the kidneys. The simple kidney cyst is different from the cysts that develop when a person has polycystic kidney disease, which is a genetic disease

    Kidney disease - Kidney disease is a condition, most often caused by diabetes or high blood pressure, in which the small blood vessels in the kidneys are damaged, making the kidneys unable to do their job. Waste then builds up in the blood, harming the body. 

    Proteinuria - Also called albuminuria or urine albumin, proteinuria is an abnormally high amount of protein in the urine. It occurs when proteins from the blood leak into the urine when the filters of the kidney, called glomeruli, are damaged. Proteinuria is a sign of chronic kidney disease (CKD), which can result from diabetes, high blood pressure, and diseases that cause inflammation in the kidney 

    Transplantation - A kidney transplant is a surgical procedure that replaces a diseased kidney or kidneys with a healthy kidney. The transplanted kidney takes over the work of the kidneys that have failed, eliminating the need for dialysis.
