Abstract
BACKGROUND: Urethral stricture may disturb both micturition and semen emission. Urethroplasty, despite the restoration of a proper urethral patency, may not eliminate the accompanying ejaculatory dysfunction (EjD). AIM: To investigate the relationship among urethral stricture, urethroplasty, and ejaculatory function. METHODS: For the systematic review, the authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Internet-based bibliographic databases (PubMed and Scopus) were searched to access studies that examined the influence of urethral stricture and urethroplasty on ejaculatory function. OUTCOMES: EjD accompanying urethral stricture, before and after urethroplasty, was evaluated. RESULTS: 20 Studies were included in the final analysis. In total, these studies comprised a population of 1,913 patients, aged between 11-86 years, 1,823 with an anterior urethral stricture and 90 with a posterior one. No randomized trials regarding the topic were found. Patients with urethral stricture typically report poor force of ejaculation, reduced ejaculatory volume, reduced pleasure, or complete failure to ejaculate. The prevalence of pre-operative disorders depends on patients' age and is more severe in the older population. The pre-operative stricture length, location, and type of surgery have no statistically significant influence on post-operative EjD. In some patients, despite a successful urethral reconstruction, problems with ejaculation persist. The improvement in ejaculation after urethroplasty is observed only in younger men. The available data are inconclusive whether the separation of the bulbospongiosus muscle during urethroplasty impairs its later functionality. CLINICAL IMPLICATIONS: Analyzing the available literature on the subject, this review provides knowledge about the possible influence of urethroplasty on ejaculatory function, which may be useful both in the pre-operative patient consultation and in the choice of treatment method. STRENGTHS & LIMITATIONS: The evidence is sufficient to determine effects on health outcomes. However, the strength of evidence is limited by the lack of randomized trials and differences in terms of methodology and analyzed populations, preclusive of conducting the meta-analysis. CONCLUSION: It has not been unequivocally determined which factors related to the stricture or surgery are decisive for post-operative ejaculatory function. The improvement in ejaculation after urethroplasty is observed only in younger men. Kaluzny A, Gibas A, Matuszewski M.
