What system does urology primarily focus on?

Urology primarily focuses on the urinary tract and male reproductive organs. This medical specialty deals with the diagnosis and treatment of conditions related to the kidneys, ureters, bladder, and urethra. It also encompasses male reproductive systems, including issues related to the prostate, testes, and penis. Understanding the intricacies of these systems is crucial for urologists, as they handle diseases ranging from urinary tract infections to prostate cancer and kidney stones.

The other options reference systems that are not the central focus of urology. The digestive tract and female reproductive organs pertain more to specialties such as gastroenterology and gynecology. Cardiovascular and respiratory systems relate to cardiology and pulmonology, while the nervous and immune systems connect with neurology and immunology, respectively. By distinguishing these systems, one can clearly grasp the unique role urology plays in healthcare.
