Abstract

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.

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).

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.
