Nontransecting Anastomotic Repair in Urethral Reconstruction: Surgical and Functional Outcomes.

Abstract

We evaluated the surgical and functional outcomes, and the effect of the learning curve of nontransecting anastomotic repair for short bulbar and posterior urethral strictures. A total of 75 patients were treated with nontransecting anastomotic repair for short bulbar strictures in 55 and for posterior strictures in 20. Surgical morbidity was scored using the Clavien-Dindo classification at 3 months. Sexual function was measured using SHIM (Sexual Health Inventory for Men) scoring preoperatively and postoperatively. Post-void dribbling before and after nontransecting anastomotic repair was also determined. To evaluate the learning curve outcomes were evaluated in patients 1 to 25, 26 to 50 and 51 to 75. Median followup was 30 months. Stricture recurred in 6 patients (8%), all diagnosed within 7 months after nontransecting anastomotic repair. Median operative time was 95 minutes and median hospital stay was 2 days. In 61 patients (81.3%) no surgical morbidity was recorded. Five (6.7%), 6 (8%) and 3 patients (4%) experienced a grade 1, 2 and 3b complication, respectively. Seven of 32 (21.9%) and 2 of 42 evaluable patients (4.7%) reported de novo erectile dysfunction and post-void dribbling, respectively, 3 months after nontransecting anastomotic repair. No difference in outcomes was observed among the 3 patient groups. Nontransecting anastomotic repair appears to be safe without a substantial learning curve effect. Patient counseling about possible surgical complications and transient erectile dysfunction is important.
