N35: Urethral stricture

N35.8: Other urethral stricture

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.

If your urethra is too narrow, it is likely that you cannot urinate properly. For example, the flow of urine may be very weak. You may feel the urge to urinate very often, particularly at night-time. The urinary passages may also become inflamed as a result of the constricted urethra.
