Urethral stricture is a medical condition that mainly affects men. According to the National Institutes of Health (NIH), very few women get urethral strictures. In addition, very few individuals are born with this condition (NIH)
Urethral stricture occurs specifically in the urethra. The urethra is a tube that carries urine from the bladder so it can be expelled from the body.
In healthy males, the urethra is wide enough for urine to flow freely through it. When the urethra narrows, it is known as a urethral stricture. Urinary flow can be slightly or severely restricted.
Urethroplasty is a open surgical procedure for urethral reconstruction to treat urethral stricture. Urethroplasty can be performed by 2 methods; primary repair which involves complete excision of the narrowed part of the urethra. The proximal and distal patent parts are then rejoined. The second method of Urethroplasty utilizes tissue transfer or free graft technique. In this method, tissue is grafted from bladder epithelium, or buccal mucosa and is used to enlarge the strictured (narrowed) segment of the urethra.
