Urethroplasty
Urethral reconstruction is used particularly to correct urethral stricture in the young or following repeated recurrence after urethrotomy.
A variety of techniques may be used:
- excision and primary re-anastomosis - particularly for for short strictures in the bulbar urethra
- excision and substitution:
- free tissue grafts - using full-thickness skin, buccal mucosa or bladder mucosa
- vascularised flaps - particularly from the hairless prepucial or penile skin
- staged procedures - particularly for long strictures and ones that have been unsuccessfully repaired previously. The first stage is concerned primarily with the excision of non-viable tissue. Later stages concentrate on retubularisation of the urethra.
