N36: Other disorders of urethra

N36.1: Urethral diverticulum

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 lined with mucous membrane.

If the urine can no longer flow out properly this may increase the pressure in the urethra. Increased pressure in the urethra over a long period of time increases the likelihood of pouches forming in the urethral wall. Pouches in the urethral wall can also be congenital, which means one was born with this condition. A pouch is protruding out of your urethral wall into your abdomen.

If the pouches or the urinary passages become inflamed, this may cause problems. You may have pain when urinating. You may often feel the urge to urinate, particularly at night-time. The inflammation in the pouches may also be causing inflammation in other organs in the abdominal area.
