And More

Dr. Ayan graduated from Medical School in 1991 and completed his urology education in 1997. At the beginning of his carrier, he was a post doctorate research fellow at the Department of Urology of Harvard Medical School, Children’s Hospital in Boston (1999-2000). He studied the effect of partial ureteral obstruction to the kidney in early developmental stage in an experimental animal fetus model. This study provided a significant contribution to a complicated issue of pediatric urology and was cited many times by its successors. 

He became associate professor of urology in 2004 and was appointed as a professor of urology in 2009. He was accepted as a clinical fellow in Minimal Invasive Urologic Oncology at the Department of Surgery, Section of Urology at the University of Chicago (2014-2015). He worked in an intense oncology program mainly concentrated on robotic surgery of prostate and kidney cancer. Because of this background, he is mainly interested in urologic oncology and pediatric urology. The primary portion of his daily practice consist of kidney cancer, prostate cancer, bladder cancer, neonatal hydronephrosis, ureteropelvic junction obstruction, urine reflux to kidney, hypospadias and undescended testis. 

Because of its prevalence in Turkey, Prof. Ayan has a huge experience with urinary stone disease and he is doing large number of endoscopic and percutaneous surgeries for kidney, ureter and bladder stones. 

Prof. Ayan holds United States Medical License and European Board of Urology Certificate. He is a member of AUA, EAU and Turkish Urologic Surgery and Urologic Oncology Societies.
