Transperineal anastomotic posterior urethroplasty with bulbocavernosus flap and fibrin sealant in the complicated posterior urethral stricture reconstruction-A retrospective cohort study.

Management of complicated posterior urethral stricture is challenging. Modified transperineal anastomotic urethroplasty (TAU) with bulbocavernosus flap interposition and human fibrin sealant provides another treatment option. We aimed to evaluate whether this technique could improve the success rate in the complicated posterior urethral stricture reconstruction in this study.

Between 2016 and 2019, 48 patients underwent either conventional or modified TAU. The criteria for success included both the absence of clinical symptoms and no need for further surgical intervention during follow-up.

Twelve patients underwent the modified TAU (group A) using bulbocavernosus flap interposition and human fibrin sealant. Thirty-six patients underwent the traditional end-to-end anastomotic urethroplasty (group B). Follow-up was 24.3-57.2 months. The patients in group A had a higher surgery success rate compared to the patients in group B (91.7 vs. 63.9%, P=0.067), with a quasi-significant result. Besides, no postoperative complications were observed in group A, while two individuals in group B had urinary incontinence, but the difference was not significant (0 vs. 5.6%, P=0.404).

Based on the preliminary results, modified TAU with bulbocavernosus flap interposition and human fibrin sealant is a safe and feasible technique for complicated posterior urethral stricture reconstruction.
