Mission Statement

To train interventional nephrologists in innovative and highly effective procedures that improve the lives of patients, such as creation and salvage of vascular access, catheter placement and manipulations, and ultrasonography for renal biopsy.

The Interventional Nephrology Fellowship Program at UW-Madison offers one year of clinical and research training as a faculty member at the clinical instructor level in the division of Nephrology. The program allows training in highly advanced interventional nephrology procedures in diverse clinical settings, allowing the ability to gain procedural competency. Interventional nephrology fellows work in the lab four days per week with full volume. As junior faculty members, fellows also begin to gain leadership experience in academic medicine. Fellows are mentored by interventional nephrologists who are dedicated to developing new techniques that will improve patients’ lives by facilitating vascular access for hemodialysis patients with novel methods of treatment and prevention. 

Interventional Nephrology Training Opportunities

Clinical locations for interventional nephrology training span both private and public sector institutions, including hospitals operated by UW Health and Wisconsin Dialysis, Inc. Interventional nephrology fellows engage in exceptionally comprehensive, non-discriminatory, and nationally renowned training that has produced outstanding interventional nephrologists in both the academic and private sectors. Highlights of training include: 

  • Fellows gain a year of clinical experience at a leading institution, teaching learners as well as training in one of the top procedure centers
  • Balance of being on service and being in procedures ensures that clinical skills are maintained
  • A robust didactic schedule with highly involved faculty
  • Opportunities to practice in both university and private practice settings
  • Diverse population of patients relative to the size of the city and region
  • Independent clinic experience, including supervision of learners
  • Exerience in advanced interventional nephrology procedures, including laser-assisted angioplasty, atherectomy, and procedures for the treatment of renal artery disease

Program History

The University of Wisconsin-Madison has played a key role in the emerging field of interventional nephrology, establishing an advanced fellowship program in 2004, shortly after the American Society of Diagnostic and Interventional Nephrology (ASDIN) was founded in 2000. Fellowship director Dr. Micah Chan is a councilor and chair of the Education Curriculum Subcommittee of the ASDIN and edited the first textbook on the subject of interventional nephrology. He and faculty member Dr. Ali Gardezi, who is an alumnus of the program, have published over 100 research publications and other scholarly works on interventional nephrology.

Highlights and Outcomes

The UW Interventional Nephrology Fellowship Program is widely regarded as the premier advanced techniques training program in the country, with former trainees enjoying successful careers in private practice or academic medicine. Many alumni currently hold faculty positions at academic medical centers throughout the United States.
