Abstract

BACKGROUND: Cystostomy, endoscopic realignment and emergency anastomosis are three methods used to treat bulbous urethral injury (BUI). The aim of the study is to determine the optimal management.

METHODS: A retrospective study was performed on 328 male patients with blunt straddle injury to the perineum. In total, 304 patients were included in the analysis due to strict criteria. Among these 304 patients, 197 had partial urethral disruption diagnosed, and 107 had complete urethral disruption. Group placement of the patients was based on the extent of injury. Each group was further divided into two subgroups based on the immediate management. Propensity score matching was used to correct for differences in baseline characteristics.

RESULTS: In the partial disruption group, the propensity score-matched subgroups set comprised of 164 patients. Of the 82 patients treated with endoscopic realignment, 34 patients (41.5%) required no urethral surgery, in contrast to 12 patients (14.6%) with cystostomy (P<0.05). No significant difference was found in the other respects (P>0.05). In the complete disruption group, the propensity score-matched subgroups set comprised of 104 patients. The success rate of emergency anastomosis was 90.4% (47 patients), and urethral stricture occurred in five patients (96%), while urethral stricture developed in all 52 patients in the cystostomy subgroup. With regard to surgical management of complications, the choice of management methods significantly differed between the two subgroups (all, P<0.05). The time to natural urination and duration of hospital stay were significantly shorter in the emergency anastomosis subgroup (29.1±5.4 days vs. 57.1±6.4 days; 7.2±3.1 days vs.12.5±2.3days, each p <0.05).

CONCLUSIONS: Endoscopic realignment is associated with a lower stricture rate than cystostomy as immediate management for partial disruption. Emergency anastomosis provides better clinical outcomes for patients with complete disruption. LEVEL OF EVIDENCE: Therapeutic Level IV.
