Prof. Dr. K. Turgay Akgül


I was born in Üsküdar in 1974.

I completed my high school education at Malatya Science High School and my medical education at Ankara University Faculty of Medicine in 1998.

In the same year, I won the Urology Clinic of the Turkish Yüksek İhtisas Hospital in the Medical Specialization Examination and started as a Urology Assistant.

I became a Urology Specialist in January 2003 and an Associate Professor of Urology in 2010.

I have over 100 scientific articles, studies and papers published in international and national journals. There are 2 scientific books that I edit and also book chapters that I wrote. At the same time, I work on the Board of Directors and Advisory Boards of international and national journals.

I am a member of European Urology Association, Turkish Urology Association, Andrology Association and Continence Association.
