Abstract

Objective: The management of recurrent posterior urethral strictures developing after pelvic fracture urethral injury (PFUI) is a challenging task. Despite availability of many surgical approaches, there is no consensus regarding the optimal approach. The objective of this study was to present our 10-year experience in the management of recurrent urethral strictures due to PFUI.

Material and methods: We did a retrospective single-institution review of patients who underwent surgical management for recurrent posterior urethral strictures from January 2006 to December 2016 using descriptive statistics. We included only those patients with PFUI who underwent some definitive surgical procedure for their previous failed repair(s).

Results: The final analysis included data of 50 male patients (10 adolescents and 40 adults). Mean age of the patients was 29.92±10.62 years. The average length of stricture was 3.02±1.47 cm. Progressive perineal urethroplasty (PPU) was done in 40 cases. Two patients with concomitant rectourethral fistula/false passage underwent transpubic urethroplasty (TPU). Three patients with complete bulbar necrosis were managed with single stage/staged preputial tube reconstruction. One patient underwent microsurgical urethroplasty using radial free forearm flap while in two patients each Mitrofanoff appendicovesicostomy and perineal urethrostomy was done. Majority of complications were minor (Clavien Grade 1 and 2). Overall success rate of PPU was 75%. Mean follow-up period was 29.46±10.68 months (range: 13-60 months).

Conclusion: Most cases of recurrent posterior urethral strictures of <3 cm in length can be operated by PPU with reasonable success rates. Complex and long-segment (higher than 3 cm) strictures require use of ancillary procedures like TPU, substitution urethroplasty and Mitrofanoff appendicovescostomy.
