Endourology Fellowship Program

Training Program Overview

Stanford's Endourology Fellowship is under the direction of Drs. Joseph Liao and Simon Conti. The one-year fellowship is approved by the Endourology Society and open to qualified applicants who have completed an accredited urology residency program. The fellowship aims to provide advanced clinical training in the endourologic management of urinary stone disease, urological cancers and benign prostatic hyperplasia (BPH), and pursuit of scholarship in basic, translational, and population health sciences within the robust research infrastructure at Stanford. Graduates of the fellowship will receive a certificate of Advanced Clinical Training in Endourology and Stone Disease from the Endourology Society as well as certification from the Stanford Graduate Medical Education office.

Clinical Training

Clinical training will focus primarily on retrograde and percutaneous surgery for urinary stone disease. Most percutaneous renal surgeries at Stanford are performed using the endoscopic combined intrarenal surgery (ECIRS) approach in the prone-split leg position. Given the large volume of urinary diversions performed at Stanford, the fellow will gain considerable experience in the treatment of stone disease through the diverted urinary tract. Fellows will also have the option of seeking out experience in novel BPH therapies such as HoLEP, Rezum and Urolift. Given the high volume of robotic-assisted surgery, experience in robotic surgery for benign urological diseases is also available. The clinical training will take place primarily at Stanford Hospital and VA Palo Alto Health Care System. Additional clinical experiences are available at affiliated Santa Clara Valley Medical Center and Kaiser Permanente Santa Clara Medical Center.

Research Training Opportunities

Fellows are exposed to a broad range of basic, translational, and population science research opportunities. Several basic and translational laboratories within the Stanford Departments of Urology and Medicine/Nephrology (i.e. Liao, Leppert, Pao) are engaged in projects germane to Endourology. Dr. Liao’s NIH-funded laboratory has been recognized in advancing urine-based molecular diagnostics and development of endoscopic imaging technologies and computer-assisted (e.g. artificial intelligence) image processing. Additional collaborative research opportunities are available through laboratories and programs within the Stanford Department of Radiology and the School of Engineering. For population science and health services research, a multidisciplinary group of investigators from urology, medicine/nephrology, and biostatistics form the core of the Stanford Urolithiasis Project that meet on monthly basis. Recent projects include identifying environmental exposures and kidney stones, epidemiology of kidney stones and clinical outcomes research using statewide, nationwide and VA datasets. Additional research training and funding support is available through a combined urology-nephrology NIH/NIDDK T32 training program and departmental resources.

Educational/Academic Opportunities

Fellows will faciliate semi-annual endourology simulation training program for residents as well as pig labs. Fellows will participate in didactic teaching for residents and medical students. Auditing and participating in university seminars and courses that will help with biostatistics and translational research are also encouraged.
