Background: Urethral stricture and its recurrence is still a major problem in male. Several procedures are present for the treatment of the disease. Lapides introduced the concept of intermittent self dilatation (ISD) which has decreased the incidence of recurrence of urethral stricture if doing properly. The aim of the this study was to report the outcomes of ISD for the treatment of urethral stricture after Filliform follower urethral dilatation (FFUD).Method: This was a prospective comparative study, conducted in the department of surgery, urology unit from March 2013 to February 2016. Total of 49 patients were enrolled and were randomly divided into Group A and Group B. In Group A, all the patients were taught ISD with Nelaton Catheter after FFUD. In group B, all patients underwent only FFUD for urethral stricture. In both groups, Foley's catheter was removed after 2 weeks of FFUD. These patients who had difficulty In passing urine or having lower urinary tract syndrome after removal of catheter, were evaluated for urethral stricture recurrency by clinical symptoms, ultrasonography, urine test for culture and sensitivity, cystoscopy/urethrogram as necessarily.Result: In Group A, 4 patients out of 20(20%)developed urethral stricture recurrency where as in Group B,18 patients out of 23 (78.26%) developed urethral stricture recurrency. Therefore, the rate of urethral stricture recurrence is significantly more in group B than the Group A (p< 0.001).Conclusion: ISD is an effective way for the prevention of urethtral stricture recurrence after FFUD. JNGMC,  Vol. 14 No. 2 December 2016, Page: 38-40

Objective: The aim is to evaluate the effect of urethral dilation on anterior urethral stricture recurrences after direct vision internal urethrotomy (DVIU). Material & Method: Patients were classified into 2 groups after internal urethrotomy for urethral dilation or observation. All strictures included were anterior, single, and causing partial obstruction. Urethral dilation was performed using a metal sound. This procedure was performed every 1 or 2 weeks in the first and second month after operation and then once a month for 1 year or in case of voiding complaints or low flow rate (< 10 mL/s). Follow up at least until 1 year after DVIU. Results: A total of 32 cases could be reviewed, of which are 21 had urethral dilation and 11 observation only. In the urethral dilation group, we found 4 recurrences (19%) with mean time to recurrence 10,52 months. In the observation group, we found 7 recurrent cases (63,63%) with a mean time to recurrence of 8,09 months. P value is 0,02 which means urethral dilation significantly decreased the chance of stricture recurrence. By Kaplan Meier survival analysis, urethral dilation had a better and longer time to recurrence. Conclusion: In this study, regular meatal dilation is proven to prolong the time to recurrence of an anterior urethral stricture after DVIU. Keywords: Urethral dilation, anterior urethral stricture, stricture recurrence.

Background: Substitution urethroplasty using buccal mucosal grafts can be performed by several approaches including ventral onlay graft, dorsal onlay graft, or ventral urethrotomy with dorsal inlay graft. Our study aims to evaluate the surgical outcome of dorsolateral buccal mucosal graft for long segment anterior urethral stricture >6 cm in patients with Lichen sclerosus (LS). Methods: A retrospective study included patients who underwent repair for long segment anterior urethral stricture >6 cm due to LS between January 2013 and April 2019. All patients were followed-up at 3, 6, 9, and 12 months postoperatively and then yearly by clinical symptoms, uroflowmetry, and calculation of post-void residual urine volume. Retrograde urethrogram was requested for patients with voiding symptoms or decreased maximum flow rate. Stricture recurrence that required subsequent urethrotomy or urethroplasty was considered failure. The success rate and surgical complications were collected and analyzed. Results: Thirty patients were identified. The median age (range) was 39 (25–61) years and a median (range) stricture length was 8 (6–14) cm. Most of postoperative complications were of minor degree. The success rate at median follow-up of 15 (12–24) months was 86.5%. The median maximum flow rate increased significantly from 6 (2–11) ml/s preoperatively to 18 (range: 6–23) ml/s at the 6th month ( p value < 0.001). Conclusion: Dorsolateral buccal mucosal grafts urethroplasty for long anterior urethral stricture caused by LS has a high success rate and low risk of complications including stricture recurrence.

Stricture Recurrence

Introduction: Internal urethrotomy is recommended for the treatment of urethral strictures shorter than 1.5 cm but has been associated with high recurrence rates. The aim of this study was to evaluate the efficacy of use of triamcinolone ointment for clean intermittent self catheterization in the prevention of urethral stricture recurrence after internal urethrotomy. Methods: Total of 60 male patients undergoing internal urethrotomy were assigned into two groups and clean intermittent self catheterization was performed using either triamcinolone ointment or a water-based gel for lubrication of the catheter in this randomized clinical trial. Clean intermittent self catheterization regimen was continued for 6 months and patients were followed for 12 months. Urethrocystoscopic evaluation was done 6 and 12 months postoperatively. Results: The recurrence rates were compared between the two groups. There were no significant differences in patient characteristics and etiology of the stricture between the two groups. There was a 6 (22.22%) recurrence rate in the patients of the triamcinolone group against 13 (46.42%) in those of the control group after the first internal urethrotomy (P=0.04). After second internal urethrotomy, the urethra was stabilized in 5 (83.3%) of the patients in the triamcinolone group and 8 (61.5%) those in the control group (P=0.05). We also found a significant correlation between recurrence and stricture length (P=0.02) but the time to recurrence was not statistically significant (P=0.16). Conclusions: The use of triamcinolone ointment in patients on CISC regimen after internal urethrotomy significantly decreased the stricture recurrence rate.
