School of Medicine - Clinical MedicineNephrology




The Department of Nephrology was established in April, 1974. We have been providing treatment, research and student education since then. We manage the Blood Purification Center, and treat out- and inpatients and do research on end stage renal failure and other various kinds of renal diseases. In collaboration with the Department of Urology, we are specialists in kidney transplantation. In 1975, we performed the first living kidney transplantation in Ishikawa. We have successfully performed 246 living and 64 cadaveric kidney transplantations since then, and we have done 2,285 renal biopsies (as of May 15, 2016). Our research is based on the areas of our expertise and we have been doing both clinicopathological and clinicoepidemiological research as well as basic research related to these areas.
In student education, we have been teaching various skills from the basics of medical terminology to actual problem solving skills through unit lectures, BSL (Bed Side Learning), CCS (Clinical Clerkship), and PBL (Problem-Based Learning). We aim to be an attractive department for students, residents and researchers.
