Step-by-step explanation:
A urologist is a physician who specializes in treating health and disease conditions related to the urinary system and the male reproductive organs. The urinary system consists of organs that include the kidneys, ureters, urinary bladder, and urethra, and is responsible for filtering waste products and excess water from the blood and excreting them from the body in the form of urine. Conditions treated by urologists include bladder infections, kidney stones, polycystic kidney disease, and urinary incontinence.
The urethra is a significant organ in the urological system, which transports urine from the bladder to the outside environment for disposal. In males,it contains the urethra and serves as an outlet for urine and semen. Urologists also perform procedures like urinalysis, an analysis of urine to diagnose various diseases.
