Dorsal onlay buccal mucosal graft urethroplasty in long anterior urethral stricture.
OBJECTIVE
To assess the success of buccal mucosal graft (BMG) urethroplasty by the dorsal onlay technique in long anterior urethral stricture (> 2 cm long) through the midline perineal incision.


METHODS
From January 1998 to December 2003, 43 patients with long anterior urethral strictures were managed by dorsal onlay BMG urethroplasty. After voiding trial, they were followed up at 3 months with uroflowmetry, retrograde urethrogram (RGU) and American Urological Association symptoms score (AUA symptoms scores). Successful outcome was defined as normal voiding with a maximum one attempt of visual internal urethrotomy (VIU) after catheter removal. Patients were further followed-up with uroflowmetry at 3 months interval and RGU every 6 months interval.


RESULTS
Mean stricture length was 4.8 cm (range 3 to 9 cm) and mean follow up was 48 months (range 12 to 84 months). Only five patients were found to develop stricture at anastomotic site, during follow-up. Two of them voided normally after single attempt of VIU. Other three patients (6.9%) required further open surgery or repeat VIU during follow up and were considered as failure.


CONCLUSIONS
Dorsal onlay BMG urethroplasty is a simple technique with good surgical outcome.
