N36: Other disorders of urethra

N36.3: Prolapsed urethral mucosa

The urinary passages include the ureters, bladder and urethra. Urine flows from both kidneys into the bladder via the ureters. The urethra channels the urine outward from the bladder. The urethra is like a movable tube. It is hollow inside. The urethral wall is lined with mucous membrane. The mucosal lining is made up of many components, the cells.

If the cells of the mucosal lining multiply, it can start to bulge into the urethra. If the bulges go all round the entire urethral mucosa, the entire urethra protrudes outwards. This is visible from outside.

If the urethra protrudes outwards, people may have problems urinating. They may possibly also have pain in the lower abdomen or between their legs. There may also be some bleeding from the urethra.
