The application of valgus urethral mucosa anastomosis in the operation of posterior urethral stricture

Purpose: To evaluate the safety and efficacy of valgus mucosa anastomosis in posterior urethra reconstruction.

Methods: We retrospectively reviewed the medical records of 116 patients who had undergone anastomotic repair of posterior urethral strictures between 2009 and 2013. Seventy-six patients underwent valgus urethral mucosa anastomosis (group A), and 40 underwent traditional end-to-end anastomosis (group B). The voiding status, complication rate, and adjuvant therapy were compared between the two groups. The clinical outcome was considered a failure when any postoperative intervention was needed.

Conclusions: The valgus urethral mucosa anastomosis could significantly improve the operation success rate of end-to-end anastomosis, reduce the stricture recurrence rate, improve the long-term urination function, and not increase the incidence of complications. So, valgus urethral mucosa anastomosis is an easy, effective and reliable urethral anastomosis technique.

Results: Patient age ranged from 11 to 68 years (mean 38.2 ± 10.6). Follow-up was 5–59 months (mean 19.5 ± 13.2). The estimated urethral stricture length was 0.5–3.5 cm (mean 1.85 ± 0.40). Of all patients, the number of patients with simple stricture and complicated stricture were 47 and 69 respectively, and there was no significant difference in the complexity of stricture between group A and group B (60.5 vs. 57.5 %, P > 0.05). Besides, there was no significant difference in the follow-up time and length of stricture between the two groups (31.6 ± 12.0 vs. 35.1 ± 14.8 months, P > 0.05). Compared to group B, the operation success rate in group A was greatly improved (92.1 vs. 80 %, P < 0.05), while the incidence of complication was similar between the two groups (31.6 vs. 27.5 %, P > 0.05).
