Ureter endometriosis is not associated with bladder endometriosis but is linked to more advanced disease stages and lesions in the retrocervix and rectum-sigmoid.

Abstract

ObjectiveTo verify whether bladder and ureter endometriosis had the same clinical features and disease behavior.DesignCase-control study.SettingMultidisciplinary group in Sao Paulo, Brazil.Patient(s)A total of 690 patients were submitted to laparoscopy with histologically diagnosis of endometriosis between July 1999 and December 2006. Twelve of these patients had lesions affecting the ureter and 26 had lesions affecting the bladder. A control group consisted of 652 patients in whom endometriosis was not affecting either the ureter or the bladder.Intervention(s)None.Main outcome measure(s)Clinical and surgical features of patients with ureteral or bladder endometriosis.Result(s)No patients with ureteral endometriosis had lesions affecting the bladder. Compared with the control group, patients with ureteral endometriosis had more advanced disease (Stages III and IV) according to the American Society of Reproductive Medicine (ASRM) staging classification (100% vs. 65.5%); they also had more retrocervical (83.3% vs. 21.6%) and rectum-sigmoid lesions (91.7% vs. 17.9%). Compared with the control group, more patients with bladder endometriosis had cyclic dysuria and/or hematuria (34.6% vs. 9.8%), more advanced stages of the disease (88.4% vs. 65.5%), and an association with endometriosis of the rectum-sigmoid (65.3% vs. 17.9%).Conclusion(s)Ureter endometriosis is not associated with the bladder disease; however, it is associated with advanced ASRM stages and with retrocervical and rectum-sigmoid lesions.
