Urology is a surgical specialty that deals with the treatment of conditions involving the male and female urinary tracts and the male reproductive organs. The field of urology involves everything from the medical management of conditions such as urinary tract infection and prostate enlargement to the surgical management of conditions such as bladder cancer, prostate cancer, kidney stones, and stress incontinence. The disorders that may be treated by urologists include those involving the kidneys, the ureters (tubes connecting the kidneys to the bladder), the adrenal glands, the bladder, and the urethra (the tube that passes urine out of the body from the bladder). In males, a urologist may also treat conditions of the testes, epididymis, vas deferens, seminal vesicles, prostate, and penis.
