About Me
I’m a urologist, with a major focus on the management of kidney stones. At The Ohio State University Wexner Medical Center, we perform more than 500 surgeries a year related to kidney stones.
Research at the Comprehensive Kidney Stone Program ties directly to our clinical program. I explore new treatments for kidney stones including medications and surgical techniques. I also study the use of lasers in the treatment of stones.
My goal is to personalize the health care delivered to each patient. I work with my patients to develop individualized treatment plans. Effective treatment of stones can provide relief of an acutely painful episode and also reduce future stone recurrences. Such treatment can significantly improve a patient’s quality of life.
My wife, Dr. Eunice Oppenheim-Knudsen, is a family practice physician who works at Ohio State’s Wexner Medical Center’s Upper Arlington Clinic. We both enjoy living in the Columbus area and working at a top tier medical center. We strive to maximize the quality of life for our patients.

Care provider does not fully provide a complete understanding of the problem and what I should expect in the future. I have a great deal of pain urinating, and have had for the last six months. The care provider doesn't have a solution for correcting the issue. I need the care provider to help me understand what's going on and correct the problem.
Highest possible feedback, he did the best job ever!
My provider is the best I could possibly have. I will not go to another and rest as confident.
Dr. Knudsen (Urology) has been caring for me for many years. He has always been exceptional, compassionate, and made efforts to refer to other specialists when needed. Together with Dr. Ganesh Shidham (Nephrology), this is the 1st time I have not required surgery in over 2 years over the last 45 years of Kidney issues. Previously, I had required multiple surgeries a year. Both Dr. Knudsen and Dr. Shidham are exceptional Dr's and people in General.
He was awesome!
answered all questions, made a plan for future care
Dr K explained everything and answered any of my questions and made me feel confident and like I had a plan to get my kidney stone issue under control.
