DORSAL ONLAY ORAL MUCOSAL URETHROPLASTY FOR ANTERIOR URETHRAL STRICTURE: A STUDY ON LONG-TERM RESULTS FROM BANSADHARA HOSPITAL, BERHAMPUR

Abstract

Background: Dorsal onlay oral mucosal graft urethroplasty, utilising a modified Barbagli technique, is used to treat urethral stricture all over the world.

Aim and Objectives: In patients with anterior urethral stricture, the purpose of this study was to look at the long-term complications, urethral function, and sexual function after dorsal onlay oral mucosal urethroplasty.

Material and Methods: Over the course of four years, a prospective, single-center study was conducted. The study comprised male patients over the age of ten who had an anterior urethral stricture of less than two centimetres and had an oral mucosal graft dorsal onlay urethroplasty. During the follow-up period, the patient's demographics, the origin of the stricture, the length and location of the stricture, early problems, and postoperative flow rates, as well as urethral and sexual function, were assessed.

Results: A total of 372 patients were involved in this investigation. The patients were 45 (14-75) years old on average, with 238 (64%) having non-lichen sclerosus aetiology and 134 (36%) having lichen sclerosus. The average length of the stricture assessed during surgery was 6 cm (2 to 15 cm). Pan-anterior strictures were the most common (39.25 percent), followed by bulbar strictures (32.80 percent ). Early problems after surgery were seen in 62 (16.67%) of patients, with parotitis (n=20) and local wound infection (n=12) being the most common. Erectile dysfunction (n=38) and post-void dribbling (n=52) were two delayed consequences that were investigated in 170 participants. A total of 32 patients (18.82%) did not respond to treatment.

Conclusion: Dorsal onlay oral mucosal urethroplasty with long-term advantages is an effective and satisfying procedure for treating anterior urethral strictures.
