Our Doctors
As urologists, our doctors are highly trained to treat disorders of the male and female urinary tract (bladder, ureter, kidney, and urethra) and the male reproductive system. Urology is classified as a surgical subspecialty, but since a wide variety of clinical problems are encountered when treating urological conditions, knowledge of internal medicine, pediatrics, gynecology, and other specialties is required.
