Endometriosis frequently affects women with genital activity and exceptionally involves the urinary tract, and the ureter in particular. From a case report of a female consulting for renal colic pain related to an intrinsic-type pelvic ureteral endometriosis, we report the difficulty in diagnosing this pseudotumoral obstruction and finding therapeutic options with a review of the literature. Ureteral endometriosis is marked by non-specific symptoms liable to delay preoperative diagnosis with a risk of deterioration of renal function due to the obstruction. Regarding the therapeutic approach, the surgical treatment associated or not with GNRH agonists seems best.
