Urology is the branch of medicine that focuses on the urinary system and the male reproductive system, including organs such as the kidneys, bladder, ureters, urethra, and in men, the prostate and testes. Urologists diagnose and treat a wide range of conditions, including urinary tract infections (UTIs), kidney stones, bladder problems, prostate issues, and male infertility. In simple terms, urology is devoted to keeping the urinary system healthy and addressing any problems that arise within it.
