Urethral strictures are narrowings of the urethra and can be congenital or consequence of infection, trauma, pervious catheterization and genital reconstructive surgery.

Patients with a urethral stricture are usually managed with an optical urethrotomy, which involves cutting open the narrow portion of the urethra. However this procedure is associated with recurrence of the stricture in almost all cases and patients will require undergoing repeated urethrotomies over the years. Therefore patients should ideally be offered a urethroplasty, which is a definitive solution and is successful in the majority of cases. This procedure involves the use of oral mucosa to reconstruct the damaged portion of the urethra. The mouth heals very quickly and patients need to keep a catheter for two weeks after the operation. Once the catheter is removed, patients are able to urinate normally.
