Harnstau durch Ureterendometriose

In endometriosis urinary tract involvement occurs in about 1 percent. While bladder involvement is more common, ureteral endometriosis can contribute to hydronephrosis and renal failure. We here report on two cases of ureteral endometriosis diagnosed due to hydronephrosis. In both cases we first relieved the kidney in placing a percutaneous nephrostomy tube into the renal pelvis. Then a laparotomy with resection and reimplantation of the ureter was performed. In one patient a resection of a segment of the rectum was also necessary because of excessive endometriosis. This patient was treated pre- and postoperatively with GnRH-agonists.
