Ureteral stricture is a disease, whereby ureter becomes narrow as a result of previous surgeries, scarring, ureteral stones, various infections or ureteral cancer. Ureteral stricture can also be caused by hydronephrosis, which is an urine flow obstruction from the kidneys. Certain bladder diseases can also cause ureter to become narrowed. Previous ureter surgeries, such as ureteroscopy, can have such complications as ureteral stricture. Ureteral stricture develops very gradually and can be latent for a period of several months before it manifests itself. The main manifestation of ureteral stricture is inability to urinate properly as the urine flow becomes extremely obstructed. In progressed cases, a person may spend hours trying to fully urinate. Urination is also accompanied by pain and in some cases - by blood in the urine.
Ureteral stricture is more common in men. It can be explained by the fact that male`s ureter is more exposed to different infections and injuries. Almost 70% of all men with ureteral stricture previously had sexually transmitted infections, fractures or injuries, which left scar tissues in ureter.
