General Info

Dr. Knudsen's specialty and/or research interests include Kidney stones/Nephrolithiasis, Ureteral stones, Bladder stones/Stone prevention, Metabolic evaluation, Stent removal/exchange, UPJ(Ureteropelvic junction) obstruction, Ureteral strictures, Hydronephrosis, Non-functioning kidney, BPH/Enlarged kidney, Hematuria (gross and microscopic), Laser surgery for prostate, and Elevated PSA (unless for biopsy) . Dr Knudsen has designed the OSU Comprehensive Kidney Stone Program to coincide with Ohio State University Wexner Medical Center's (OSUWMC) philosophy of research, patient care, and education. He 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 was recently elected as one of the youngest members of the prestigious ROCK (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. Dr Knudsen is committed to providing the best state-of-the-art treatment options for stone disease and has worked closely with leaders within OSUWMC to ensure the best possible infrastructure is in place. This has resulted in the development of an outpatient facility centered around a Storz SLX-F2 shockwave lithotripsy machine (the only one of its kind in central Ohio), the latest flexible endoscopes which make even the most difficult to reach stones treatable, and a 100W holmium:YAG laser capable of breaking up any type of kidney stone.
