BACKGROUND: Rectourinary fistula (RUF) is an uncommon but devastating condition in men. It usually occurs as a complication of prostatic cancer treatment, whether this is by radiation therapy or surgery. It can also occur in patients with benign pathology of the prostate, inflammatory bowel disease, or Fournier's gangrene, and following pelvic trauma. RUF represents a challenge for the surgeon because spontaneous closure is a rare event. Several techniques have been described for surgical repair of fistula. The goal of the present study was to demonstrate that the York Mason posterior, transrectal correction of an iatrogenic RUF is a reliable approach that offers good postoperative outcomes. METHODS: We retrospectively reviewed the medical records of 39 patients who underwent York Mason repair from 1998 to 2012 at the University of Southern California (USC) and Campus Bio-Medico University of Rome (UCBM). The most frequent common causes of RUF were itemized, and statistical analysis was performed to determine correlations between the fistula's etiology and surgical outcome. Patients were then divided into two different cohorts: those who had undergone only one previous procedure (group 1) and those who had undergone two or more surgeries (group 2). We performed a statistical analysis between the two groups and calculated the percentage of fistula repair by means of the posterior trans-sphincteric approach with the York Mason technique in each groups We evaluated the presence of comorbidities (diabetes and infection) and their influence on the surgical outcome. Finally, we reported patient outcomes during follow-up. RESULTS: In the present series, the RUF was iatrogenic in every case. The onset of the fistula followed prostate cancer treatment, most commonly after laparoscopic procedures. The success rate of fistula repair was found to be independent of the fistula's etiology. Diabetes and infections did not influence the surgical outcome. Overall, more than 50 % of patients treated with the York Mason posterior, transanal, transrectal approach remained free of fistula during follow-up. Almost 90 % of those who were previously operated only once remained free of fistula. CONCLUSIONS: The posterior trans-sphincteric approach of the York Mason technique is effective in treating RUF.
