Modified York-Mason technique for repair of iatrogenic rectourinary fistula: the montsouris experience.
OBJECTIVE
Rectourinary fistula is a devastating complication of rectal and genitourinary surgery. Spontaneous closure is rarely successful and failure in conservative management calls for surgical intervention. We present our experience with rectourinary fistula repair using a modified York-Mason technique.


METHODS
We retrospectively reviewed the medical records of all 12 patients who underwent modified York-Mason repair at our institution between 1998 and 2008. Rectourinary fistula developed in 10 patients after radical prostatectomy and in 2 following high intensity focused ultrasound. Six patients were initially treated with fecal diversion. Our approach begins with a transanal incision at the 2 o'clock position representing a modification of the classically described midline incision extending from the coccyx to the anal verge. Key aspects of the York-Mason procedure are maintained. However, we do not close the urethra after fistula excision, and instead perform a multilayer, nonoverlapping closure of the anterior rectal wall only.


RESULTS
With a median followup of 22 months we observed the complete resolution of rectourinary fistula in all 12 patients. Three patients required multiple York-Mason procedures to achieve resolution of symptoms. All patients reported intact fecal continence. Median operative time and estimated blood loss were 63 minutes and 100 ml, respectively. Median hospital stay was 4 days.


CONCLUSIONS
Our modified York-Mason technique is safe and effective for the repair of small, iatrogenic rectourinary fistula. We report 75%, 92% and 100% rectourinary fistula resolution after 1, 2 and 3 York-Mason procedures, respectively, with 100% fecal continence. This technique can be performed multiple times without a significant increase in operative time, estimated blood loss or fecal incontinence.
