Nephrology Division Campuses

Mount Sinai Beth Israel

The Division of Nephrology and Hypertension was formed over 25 years ago, when E. Lovell (“Stretch”) Becker was chairman of the Department of Medicine, to care for the rising number of patients with kidney disease on the Lower East Side of Manhattan. The division expanded and opened a research laboratory and a dialysis unit for both acute and chronic kidney disease. Within a few years, the Division of Nephrology and Hypertension became the dominant research center for dialysis in Manhattan and the rest of the world. During the 1990’s, the peritoneal dialysis program was considered one of the premier programs in the country.

Today, the division continues to treat a large number of dialysis patients with the most advanced dialysis procedures, and we are actively involved in many research projects with these patients to improve treatments and outcomes. We are also involved in clinical research of other aspects of renal disease with patients at all stages of kidney disease. We are focused on preventing kidney disease in the context of overall cardiovascular risk reduction. The Division of Nephrology and Hypertension is recognized nationally as a leader in the refinement of state-of-the-art technology for both hemodialysis and peritoneal dialysis. We are actively involved in research projects to improve treatments outcomes, and prevent kidney disease within the context of overall cardiovascular risk reduction.
