Nephrology Fellowship | | Loyola Medicine

Nephrology Fellowship

Our fellowship seeks applicants whose goals are to provide State-of-the-Art Care to their patients. The Nephrology Fellowship Program at Loyola is a fully accredited program that awards three new fellowships each year. The program provides training that is structured to meet the goals of each individual trainee, while integrating the science of medicine into the practice of Nephrology with an ongoing interest in primary care.


Clinical Training

This two year Nephrology Fellowship Program provides the trainee with the requisite experience in the evaluation and management of patients with a broad range of renal-related disorders (including but not limited to acid-base physiology, fluid and electrolytes, acute and chronic renal failure, continuous renal replacement therapy, hemodialysis, peritoneal dialysis, renal transplantation, glomerular diseases, nephrolithiasis, and hypertension).  The trainee will learn these objectives by supervised direct patient contact, research seminars, journal clubs, renal pathology conferences, biweekly clinic-pathological conferences, morbidity and mortality conferences, a dialysis and interventional nephrology seminar series, renal transplant conferences, and monthly review of a basic physiology topic facilitated by an attending nephrologist.  The trainee will have opportunities to assume responsibility under appropriate supervision for the care of patients in continuity clinics. Our fellows also participate in quality improvement projects to acquire the requisite skills to work effectively as a member of a multidisciplinary team.


Fellows rotate through the inpatient, outpatient and consultative inpatient services of Loyola University’s Foster G. McGaw Hospital and the Edward Hines, Jr. VA Hospital. The distribution of ages and genders in our clinics approximates their distribution among the general population with chronic kidney disease and its related-disorders.  The fellows also round at the Loyola and Hines dialysis units to acquire firsthand experience in managing patients with end stage renal disease and leading a multidisciplinary management team.  Additionally, the fellows spend time in dedicated renal transplant clinics and participate in interventional nephrology procedures.

Research is a required component of the training program.  Fellows have protected time during designated research rotations. The goals of this requirement are to give fellows an appreciation of the scientific method, the design and conduct of a research project, the analysis of data, and, where applicable, the requirements for research involving humans (IRB and the informed consent process) and/or animals (IACUC training).
