Introduction. The frequency of recurrence after various types of surgical treatment of urethral strictures (US), according to the literature, ranges from 15,6 to 36,4%.
The main goal of this study was to evaluate predictors of recurrence after surgical treatment of US.
Materials and methods. Analysis of the treatment results of 206 patients who underwent one of the surgical treatment types between 2010 and 2019. Three groups of patients included visual internal urethrotomy (VIU), anastomotic urethroplasty or buccal mucosa graft urethroplasty. Statistical analysis using univariate and multivariate analysis, χ2-test, odds ratio was used to evaluate the results. ROC – analysis was performed to determine the significance of the stricture length in the recurrence rate.
Results. The main predictors of recurrence were: length (p=0,037), multifocal US (p=0,039), recurrent (p=0,016) strictures, number of previous operations (p=0,041), etiology (p=0,042) – in the group VIU; localization (p=0,044), obliteration of the urethra (p=0,018) – after anastomotic urethroplasty; patient age (p=0,005), multifocal type of US (p=0,014) – after buccal mucosa graft urethroplasty.
Conclusions. The overall success rate in patients of the three groups after undergoing types of surgical treatment in the short-term period was 73,27%, in the long-term period – 62,94%.
