Ervin Kocjancic, MD

Professor of Surgery

[MUSIC PLAYING] My name is Ervin Kocjancic. I realize this can be difficult to remember or to understand. A lot of patients and people calls me Dr. K, which is perfectly fine. My specialty, I'm a urologist, which is a very ancient specialty, one of the first recognized in the history of medicine. And we are dealing basically with everything from the urinary tract and mostly male and some female genital dysfunctions.

I decided to start with the medical career from a very young age. I was one of those kids that never wanted to go to sleep, and the parents are pushing you. You need to go to sleep. You need to go to sleep earlier. I say, when I grow up, I'm going to be either a policeman or a doctor, because they don't have to go to sleep that early. And so that's the initial reason.

Then, growing up, I realized that I can do a lot more for, in general, the humanity, the patients, so take care of and share problems that they have and make their life better. I add this to the never going to sleep with the patient.

My philosophy is trying to understand the patients and the family and try to be close to them. Despite wearing a suit-- I tend to wear a suit when I talk with the patients and when I interact with the patients, but I want to be more of a friend and advisor and take care on a very personal level. So I have the advantage of speaking a few languages, and I try to communicate in patient's own language, because we are dealing with a very specific area, very intimate part of our bodies. So being able to communicate in your native language, I think it's a big advantage.

I specialized in reconstructive urology. It means everything that requires rebuilding the part of the urinary tract or genitals in both gender, so male and female. And I started five years ago building a center for gender-affirming surgery, and this is one of the area of expertise that I really want to build up at the University of Chicago, especially for the patients from the South Chicago, which is a pretty underserved area, but not limited to South Chicago, not limited to Chicago only, not limited to Illinois only. I'm building knowledge and spreading influence in basically in the whole world.

Ervin Kocjancic, MD, is a skilled reconstructive urologist who specializes in pelvic health, urinary incontinence, and reconstructive surgery for female, male and transgender patients with an expertise in gender affirmation surgery and complex reconstructive genitourinary conditions.

Because of his devotion to investigating new and/or better treatments for urologic conditions, mentoring students and improving care for patients, Dr. Kocjancic has received numerous awards and citations for presentations, research, teaching and clinical service.

He is also active in several international medical and service organizations, promoting the practice and importance of urology around the world. He is on the editorial board of the International Urogynecology Journal, was chair of the ICS International Continence Society's Education Committee and is a member of the International Neurourology Society's board of directors.

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
