Prostate cancer is the first cancer amongst men with more than 50000 cases per year in France. Surgical, radiation, frost, or ultrasound induced rectourethral fistula is a rare complication (<1%) of localized prostatic cancer treatment but hard to manage. Different types of treatment exist: conservatory, trans-sphinteric (York-Masson), transanal, perineal, with or without muscle flap interposition. Gracilis flap interposition for rectourethral fistula management is a promising technique but few cases are described and functional results are scarce.

The aim of this study is to present surgical and functional outcomes of rectourethral fistulas surgery with gracilis flap interposition after treatment of localized prostate cancer.
