In the latter case, several techniques are used taking into account several factors. Our objective was therefore to investigate the possible prognostic factors of failure of this surgical management. Material and Methods: We conducted a retrospective study from January 2006 to December 2017 on patients admitted to the Urology Department of the Mohammed 6 University Hospital of Marrakech for management of post-traumatic posterior urethral stenosis. The parameters studied were age, medical and surgical history, causes, characteristics of the stenosis (location, number, length), associated lesions, surgical technique used, and evolution. The descriptive analysis consisted of calculation of absolute and relative frequencies for the qualitative variables, and of position and dispersion parameters for the quantitative variables (mean, standard deviation). In bivariate analysis, the comparison of categorical variables used Pearson’s Chi-square statistical test and Fisher’s test if necessary. The significance threshold was set at p Results: A total of 30 cases were selected. The age of our patients varied between 18 and 68 years, with an average of 38.33 years (16 - 80 years);the most affected age group was between 20 and 39 years. The mode of revelation of urethral damage was dominated by acute retention of urine present in 76% of patients, followed by dysuria (33%). The stenosis extended over 21.91 mm on average (14 - 40 mm). It was accompanied by bone involvement in 15 patients (53.3%). Erectile dysfunction was present in 23 patients (23%). Terminal urethrogram was the main surgical technique used, followed by internal urethrotomy (60% and 30% respectively). 15 patients had a recurrence, with an average of 1-second operation. Statistical analysis of the different factors studied showed no correlation with the occurrence of recurrence after surgical treatment. Conclusion: The medium and long term results of anastomotic repair of the posterior urethra do not seem to depend on the lesion parameters of the stenosis (site, number, extent, presence of associated bony lesions or erectile disorders).展开更多
