Urology is a specialty that deals with diseases of the male and female urinary tract (kidneys, ureters, bladder and urethra) and the male reproductive organs (penis, testes, scrotum, prostate, etc.). Since the conditions that affect the genitourinary tract can occur in males and females of all ages, urologic health is important for everyone. Although urology is classified as a surgical specialty, a knowledge of internal medicine, pediatrics, gynecology and other specialties is required by the urologist because of the wide variety of clinical problems encountered.
