Colorectal resection for endometriosis is a major operation exposing patients to the risk of severe digestive and urological complications. The objective of this review is to evaluate surgery-related urological morbidity of which little is known to date. We searched MEDLINE for articles published on colorectal resection for endometriosis between 1998 and March 2011 using the following terms: “bowel”, “rectal”, “colorectal”, “rectovaginal”, “rectosigmoid”, “resection” and “endometriosis”. We were not able to perform a meta- analysis due to a lack of complete data on urological complications so have focused this review on voiding dysfunction and ureteral injury. Thirty-two articles reporting on 3047 colorectal resections for endometriosis including 1930 segmental resections, 271 discoid resections and 846 rectal shavings were analysed. For voiding dysfunction, 28 series including 2563 colorectal resections were available. Postoperative voiding dysfunction varied from 0% to 30.4% with a mean value of 3.4% (73/2118). Fourteen series reported an incidence of ureterolysis comprising between 8.5% and 100% with a mean value of 46% (815/1772 patients). The risk of urinary fistulae evaluated in 26 series was estimated at 0.9% (24/2581 patients). Only one case of hydronephrosis was reported in 9 series including 1256 patients (0.07%). The incidence of urological morbidity associated with colorectal endometriosis is poorly documented and probably underestimated due to the short follow-up reported in the series. Moreover, as complication rates varied widely according to the type of surgery and the experience of the teams, further studies are required to identify risk factors of urological morbidity so as to adequately inform patients.
