What field of medicine focuses on urine and urinary tract diseases?

Urology is the field of medicine that primarily focuses on the diagnosis, treatment, and management of conditions related to the urinary tract in both males and females, as well as the male reproductive system. This specialty encompasses a wide range of issues, including kidney stones, urinary incontinence, bladder and kidney infections, and cancers of the urinary system. Urologists are specially trained to handle both surgical and non-surgical aspects of urinary tract health.

Nephrology, while closely related, specifically centers on the kidneys, their functions, and diseases, which means it does not cover the entire urinary tract. Gynecology is focused on women's reproductive health, and endocinology pertains to hormone-related conditions and the glands that produce hormones. Each of these fields occupies distinct areas within medicine, with urology being the correct answer for issues related to urine and the urinary tract.
