OSU Comprehensive Kidney Stone Program




Meet Bodo Knudsen, MD


Bodo Knudsen, MD is the director of the OSU Comprehensive Kidney Stone Program. He completed his residency training in urology at the University of Manitoba under Program Chairman, Dr. Denis Hosking, himself a key opinion leader in metabolic stone disease and retrograde renal stone surgery. After residency, Dr. Knudsen pursued fellowship training at the University of Western Ontario in endourology and laparoscopy under Dr. John Denstadt, a world expert in the surgical management of kidney stones. After fellowship training, Dr. Knudsen was recruited to The Ohio State University to develop the Comprehensive Kidney Stone Program.


Dr. Knudsen is committed to providing the best state-of-the-art treatment options for stone disease and has worked closely with leaders within OSUMC to ensure the best possible infrastructure is in place. This has resulted in the development of an outpatient facility located at the Eye and Ear Institute at Gowdy Field of The Ohio State University Wexner Medical Center.


There are 2 main approaches to treatment of kidney stones:

Ureteroscopy with laser lithotripsy

Percutaneous nephrolithotomy (PCNL)



Located in the new Cystscopy Suite is the UROSKOP cysto table, which allows use of the latest flexible endoscopes which make even the most difficult to reach stone treatable, and a 100W holmium:YAG laser capable of breaking up any type of stone. The Comprehensive Kidney Stone Program also provides patients a continuum of care through its metabolic clinic.

Dr. Knudsen has designed the OSU Comprehensive Kidney Stone Program to coincide with the institution's philosophy of research, patient care, and education. Dr. Knudsen leads an active research program, focusing on improving the surgical management of stone disease. This research has led to Dr. Knudsen being recognized as a world expert in the use of lasers to treat kidney stones. He is a member of  the R.O.C.K. (Research on Calculus Kinetics) Society, a group of international investigators who focus on kidney stone research. Dr. Knudsen has also partnered with other experts in the field, both nationally and internationally, which has led to multicenter studies aimed at improving the treatment of kidney stones.

The Ohio State University Medical Center is the only central Ohio hospital or health system to be ranked as one of the Best Hospitals by U.S. News & World Report in the specialties of urology and kidney disease.
