Urology focuses on the male reproductive system and the urinary tracts of both men and women. The organs covered by urology include the kidneys, the urinary tracts and the bladder, as well as the male reproductive organs such as the testicles, prostate, and penis. Urology involves both surgical and non-surgical treatments. It is closely related to onocology, nephrology, gynecology, dermatology and endocrinology.
