Effects of Combination of Bi-inject (Triamcinolone and Mitomycin) After Direct Vision Internal Urethrotomy for Short Urethral Strictures

Abstract

Background: Urethral stricture disease has always been a challenge for urologists. Different treatment modalities that are used for treatment of urethral stricture disease, however recurrence has been a persistent problem. Agents such as triamcinolone and mitomycin-C offer hope but merit to be researched. Objective: To test the combination of triamcinolone and mitomycin in direct vision internal urethrotomy (DVIU). Methods: This quasi-experimental analysis was conducted in Ziauddin Hospital North Nazimabad upon a sample of 116 patients (selected using non-probability, consecutive sampling) in two groups (A: Experimental and B: Control) of 58 each. Data was recorded onto a structured questionnaire containing inquiries pertaining to basic biodata, sociodemographic details, disease history, operative notes and post0operative follow-up. The data obtained was analyzed using SPSS 21.0 and MS. Excel 365. Results: The mean age of the sample stood at 47 (SD ± 05) years, with the age ranging from 19 to 80 years. The etiology was idiopathic in most (55.2%) of the cases and the primary urethral strictures were the commonest (67.2%). Most strictures appeared between 6 to 9 months after the procedure and the incidence decreased with passage of time till no new cases were reported at 1 year. The outcome of the treatment in group A bi-inject given was regarded as success in 49 (84.5%) and in group B bi-inject not given was 32 (55.2%) of the cases. Among those that experienced a recurrence, majority (63%) of the patients experienced bulbar urethral stricture, while the remaining (37%) faced membranous urethral strictures. Few complications were seen in both groups, predominant among which was bleeding. Conclusion: After careful consideration, it is concluded administration of triamcinolone and mitomycin in direct vision internal urethrotomy (DVIU) yields a successful outcome significantly (<0.05) more frequently (84.5%) than the control group (52.5%).
