Urology is a field of medicine that focuses on disorders in both the male and female urinary tract, as well as conditions involving male sex organs. Your urinary system works to regulate wastes found in your urine and can run into problems just like any other system in the body. When it comes to problems that arise in your urinary system, including your kidneys, bladder, ureters, and urethra, it's best to consult a urologist.
