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.

Positive, pleased with surgery results.
Very impressed
Listens, advises, cares
It was perfect
Love Bodo always makes sure to cover the essentials and Infeel better when I leave bc of my confidence in him as a doctor
The care provider did not seem interested in our concerns about kidney stones resulting in an infection that lowers my brothers seizure threshold increasing the likelihood of hospitalizations. When trying to stress our concerns and the concerns of the neurology specialists that treated my brother during his 3 week stay in the hospital the clinician was extremely dismissive. He told us that "we don't treat seizure patients any differently". My brother has a very complex and serious seizure disorder and his disregard for all our concerns (that mainly came from the OSU neurology team) has caused us to cancel all future appointments and will see another provider.
He is a wonderful Doctor, everyone was very nice, had exceptional care during my hospital stay and surgery.
Attentive. Let me watch the procedure on the screen. Told me next steps.
It was the very best care
Dr. Knudsen was the first of three urologists I have dealt with who seemed to know what he was doing in my particular situation. The first didn't seem to know what to do and seemed to wash his hands of the who thing and the second seemed to care but his solution struck me as not particularly feasible (and Dr. Knudsen said my instincts were correct).
I was surprised how much time the Dr. Knudsen spent with me. Reviewing my CT scan with me was very educational. We've done this before, and all went well.
He is amazing
