Urologists specialize in conditions and diseases of the male and female urinary tract (e.g., kidneys, ureters, bladder and urethra). Their knowledge also lies within male reproductive organs (e.g., penis, testes, prostate, etc.). Urology is a broad specialty that encompasses a wide range of clinical issues and focuses significantly on surgery.

Stamford Health Medical Group urologists have extensive knowledge of internal medicine, gynecology, nephrology, and other related areas that enable us to determine when surgery is indicated. Our experience in all aspects of endoscopic, robotic (minimally invasive), and open surgical techniques appropriate for your specific condition is what sets us apart.
