Urologists treat disorders of the kidneys, ureters, urinary bladder and urethra. For both men and women, the urologist will diagnose and participate in treatment of cancers as they affect those parts of the body, and he'll treat urinary stones, injuries and infections.
The urologist is also the specialist who will diagnose problems with male reproductive organs. Other than skin cancer, prostate cancer is the most common cancer in American men. Approximately one in six men will be diagnosed with prostate cancer in his lifetime, and one in 36 will die from this disease [source: American Cancer Society]. With these rates, it's easy to understand why this specialty is needed in the Army Medical Corps.
