Brief Insight about long-term sequelae of pelvic fracture urethral injury Repair and their Management

Abstract

Pelvic fracture urethral injuries (PFUI) represent a significant urological challenge, often resulting in long-term functional sequelae that significantly impact patients' quality of life. Effective management necessitates a multidisciplinary approach encompassing immediate stabilization, meticulous surgical repair, and comprehensive long-term follow-up. Immediate management focuses on haemodynamic stabilization and preventing further urethral injury. This often involves suprapubic catheterization to divert urine and allow for delayed definitive urethral reconstruction. The timing and technique of surgical repair remain controversial, with factors such as injury severity, patient comorbidities, and surgeon expertise influencing the choice between primary or delayed reconstruction. Options include primary anastomosis, buccal mucosal graft urethroplasty, and various flap techniques, each with specific indications and potential complications. Pelvic fracture (PF), while infrequent, presents a significant urological challenge, with pelvic fracture urethral injury (PFUI) occurring in 1.6% to 25% of cases. Initial assessment necessitates a comprehensive history and imaging, including immediate cystourethrography, with potential for repeat imaging and MRI later to guide management. Preoperative imaging (cystourethrography and MRI) can predict the complexity of delayed urethroplasty, which is the gold standard treatment, usually performed at least 3 months post-injury after stabilization of other injuries. In men, this typically involves a bulbo-prostatic anastomosis; corpora splitting, partial inferior pubectomy, and in rare cases, total pubectomy or urethral rerouting, may be necessary to achieve a tension-free repair. Complex PFUI cases (e.g., significant urethral gap, bulbar necrosis, failed endoscopic realignment, pubic symphysis hardware, pediatric PFUI, previous urethroplasty failure, concomitant anterior urethral stricture, or recto-urethral fistula) warrant referral to experienced centers. Surgical reconstruction achieves urethral patency in approximately 86% of cases. Postoperative evaluation should proactively address potential complications, including erectile dysfunction and urinary incontinence, to optimize patient outcomes.
