Urology can be defined as the diagnosis and treatment of diseases of the urinary or uro-genital tract in a single line.
Urology is the field of medicine that focuses on the urinary tracts of and reproductive system. It is "multidisciplinary" as it includes management of "medical" (ie., non-surgical) problems such as urinary infections and "surgical" problems such as the correction of congenital abnormalities of the urinary / reproductive systems and the surgical management of cancers involving the urinary and (male) reproductive organs. It includes the urethra, kidneys, ureters, urinary bladder, the male reproductive organs including the foreskin, testes, epididymis, vas deferens, seminal vesicles, and prostate.

In both sexes, the urinary and reproductive systems are close together, and often both affected by disease or disorders of one or the other
