Abstract
Male urethral stricture continues to be a common and challenging urologic condition. Various options for management of urethral stricture disease are available ranging from urethral dilatation, internal urethrotomy, urethral stenting, and progressing to anastomotic and substitution urethroplasty. Despite the high failure rate of direct vision internal urethrotomy (DVIU), it remains the most commonly performed procedure for the treatment of urethral strictures, as it is fast, simple to perform, and is associated with a short convalescence.
In the current study, (103) patients with anterior urethral stricture were treated with DVIU. The site of urethral stricture was bulbar in (56) cases, bulbo-penile in (30) cases and penile in (11) cases. The etiology of the stricture was iatrogenic in 14 cases (14.5%), unknown in 40 cases (41.5%), infective in 7 cases (7%) and Traumatic in 8 cases (8%), BXO and lichen sclerosus in 12 cases (12.5%) and secondary to failed hypospadias repair in 16 cases (16.5%).
Percentage of successful outcome in patients who underwent DVIU for the first time was (82%) with bulbar strictures, (32%) with bulbo-penile strictures and (20%) with penile strictures, while in recurrent cases, the success rate was (31%) with bulbar strictures, (27%) with bulbo-penile strictures and (17%) with penile strictures.
Success rate was (79%) with urethral strictures less than 1 cm in length, while it was (39%) with urethral strictures (1 - 2) cm in length.
There was no significant difference in success rates of the three different groups (5, 7 and 10 days) in duration of urethral catheterization following the procedure.
The duration of recurrence after DVIU was (10 ± 3 months) with iatrogenic strictures, while it was (6 ± 2 months) with strictures secondary to failed hypospadias repair. It was earlier (5 ± 2 months) with penile strictures, while it was later (11 ± 3 months) with bulbar strictures. Also, it was (6 ± 2 months) with strictures (one - two cm) in length, while it was (10 ± 3 months) with strictures less than one cm in length.
Eventually out of the 103 patients (6) missed follow up. 51 patients (49.5%) had successful outcome, while 46 patients (44.5%) had failed outcome.
