Comprehensive analysis of paediatric pelvic fracture urethral injury: a reconstructive centre experience

Abstract

To analyse our experience in pelvic fracture urethral injury (PFUI) in children and adolescents, with various anastomotic urethroplasties (AUs) used to accomplish tension-free anastomosis described and their surgical outcomes evaluated. Patients and methodsFrom 2008 to 2019, 192 cases including both primary and redo PFUI, which comprised 181 boys and 11 girls aged ≤18 years. The results are presented separately according to gender. Moreover, the two populations were divided in two age-related sub-groups for sensitivity analyses: Group 1 (children) aged ≤11 years and Group 2 (adolescent) aged 12-≤18 years. ResultsThe median (interquartile range [IQR]) age at presentation in our series was 14 (9-17) years for boys and 9 (6-10) years for girls. Primary vs redo cases were 85 (47%) vs 96 (53%) in boys and 10/11 vs one of 11 in girls. In the primary male cases (85), the bulbo-membranous junction was the commonest site of injury (63, 74.1%). In boys, transperineal AU (TPAU) was performed in 160 (88.4%) and transpubic urethroplasty (TPU) in 17 (9.4%). In girls, TPU was utilised in nine cases, where two received meatoplasty and vaginal episiotomy. In boys, the overall success rate for TPAU was 81.2% and in primary PFUI cases success for TPAU was 88.3%. Overall success for TPU was 64.7%. In girls, the success rate for TPU was 100%. In boys and girls, the success rates for various AUs utilised between the child and adolescent groups were comparable. The median (IQR) hospital stay was 3 (3-4) days for boys and girls. The median (IQR) followup duration was 25 (16-33) months and 20 (17-27) months for boys and girls, respectively. Secondary procedures were performed in 39 boys and one girl, which comprised laser optical internal urethrotomy in 26 (14.4%) boys and redo surgery in 13 (7.2%) boys and one (9.1%) girl. Of all patients, four of the 11 girls and 74 boys (38.5%) were lost to follow-up. ConclusionsMost paediatric PFUI can be addressed via a transperineal approach with reasonable long-term outcomes. In challenging cases salvage procedures utilising vascular-based flaps as a urethral substitute give satisfactory results. Even young children can be managed with a high success rate in expert hands and these injuries should be addressed by specialist reconstructive urologists.

Summary of emergency treatment experience of acute urethral trauma in girls

“…The European Association of Urology recommends early repair (within 7 days) of urethral injuries in female patients rather than delayed repair or urethral realignment [10]. Although the treatment of urethral injuries in girls utilizes some of the same treatment strategies as in adults with successful outcomes described in numerous reports [11][12][13], there is currently no consensus on the optimal treatment method for urethral injuries in girls. Controversy regarding the optimal timing and method of surgical management has been ongoing for decades.…”

Management of Pelvic Fracture Urethral Injury: Is Supracrural Urethral Rerouting (Step 4) Becoming Anecdotical or Does It Remain in Force?

“…The site of urethral injury is the bulbo-membranous junction in most patients [ 3 , 4 ]. Rarely, the urethral injury is localized in the prostate-membranous junction, as can happen in children [ 5 ], intraprostatic, and/or at the bladder neck.…”
