Novel Utilization of a Penrose Drain as a Spacer During Temporary Artificial Urinary Sphincter Explantation and Rectourethral Fistula Repair

A 65-year-old male patient with a history of external beam radiation therapy for prostate cancer and multiple urological surgeries developed a rectourethral fistula after treatment for urethral diverticulum with stones. In managing this complex case, a Penrose drain was utilized as a spacer during artificial urinary sphincter cuff removal to preserve the urethral space for future sphincter re-implantation. This report highlights the novel application of a Penrose drain as a spacer in urological surgery and its benefits in minimizing tissue contraction and preserving urethral health.
