Fellowship in Nephrology at Staten Island University Hospital

The Division of Nephrology at Staten Island University Hospital is accredited by the Accreditation Council for Graduate Medical Education (ACGME). The division includes a two year clinical fellowship program designed to provide comprehensive training in clinical practice as well as transplantation, hypertension, and dialysis.

The mission of the nephrology fellowship program is to provide a high quality educational and research experience in the field of nephrology. The process shall involve regular teaching by the members of the Division of Nephrology and the program director. The program provides an in-depth exposure to clinical nephrology and extracorporeal treatments in inpatient, critical care and outpatient settings.

Since the start of the nephrology fellowship program there have been 10 graduating fellows. Our fellows come to our program after completing their residency at hospitals all over the country such as: Staten Island University Hospital, New York University, Seton Hall Internal Medicine Residency Program, Coney Island Hospital, and the University of Nevada School of Medicine (Las Vegas).

Our graduates have been very successful in their careers after completing their nephrology fellowship program. The majority of the graduates are now nephrologists in private practice or in hospitals in New York, West Virginia Texas and Georgia. One graduate was accepted to the Renal Transplant Program at Emory University in Georgia and is now a faculty member there. Two graduates have pursued careers with companies such as American Access and Eli Lilly and Company. Dr. El-Charabaty, the program director, was also a graduate of the program and another graduate has just joined our faculty.

Staten Island is a borough of New York City, and is only 25 minutes away from Manhattan. Staten Island University Hospital is easily accessed by car, bus, ferry, or train. Affordable housing is available in the quiet communities that surround the hospital grounds.

Our clinicians, educators and researchers are dedicated to delivering the highest quality care, while continually pushing the boundaries of knowledge.

The nephrology fellowship program is an ACGME accredited program at Staten Island University Hospital that offers two years of training in general nephrology.

The fellowship consists of a comprehensive training experience in all aspects of clinical nephrology, including acute and chronic hemodialysis, continuous renal replacement therapy, peritoneal dialysis, renal transplantation, hypertension, and all forms of fluid, acid-base, and electrolyte disturbances. Nephrology fellows will become adept at the placement of temporary vascular access for hemodialysis and percutaneous native and transplant renal biopsy. In addition, fellows will receive instruction and mentoring in nephrology research with protected time to engage in meritorious activities.

Fellows are afforded protected time to conduct clinical research throughout the duration of the fellowship. Each fellow is assigned to a teaching nephrologist who serves as a mentor for the development and successful completion of a research project.

The fellows are encouraged to develop their consultation skills by means of experience in the delivery of lectures, the evaluation of patients, and the development of teaching slides and educational files.
