INTRODUCTION: Iatrogenic urethral injury and rectourethral fistula are rare and challenging complications of pelvic surgery.
CASE PRESENTATION: Case 1 involved a 72-year-old man with persistent urinary leakage after primary repair of a prostatic urethral injury sustained during rectal cancer surgery following neoadjuvant chemoradiotherapy. Approximately 2 years later, reclosure of the urethral defect with local periurethral reinforcement and gracilis muscle flap coverage enabled catheter removal and spontaneous voiding. Case 2 involved a 62-year-old man who developed a rectourethral fistula after robot-assisted radical prostatectomy. After conservative management failed, fistulectomy, rectal and urinary tract repair, and gracilis muscle flap interposition achieved fistula closure and subsequent colostomy reversal.
CONCLUSION: These cases illustrate two distinct reconstructive roles of the gracilis muscle flap: vascularized reinforcement of a compromised urethral repair and interposition between repaired urinary and rectal sites.
