title: Endometriosis of the ureter and bladder are not associated diseases.
abstract: OBJECTIVE
  To verify whether bladder and ureter endometriosis had the same clinical features and disease behavior.
  
  
  METHODS
  Case-control study.
  
  
  METHODS
  Multidisciplinary group in Sao Paulo, Brazil.
  
  
  METHODS
  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.
  
  
  METHODS
  None.
  
  
  METHODS
  Clinical and surgical features of patients with ureteral or bladder endometriosis.
  
  
  RESULTS
  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%).
  
  
  CONCLUSIONS
  Ureter endometriosis is not associated with the bladder disease; however, it is associated with advanced ASRM stages and with retrocervical and rectum-sigmoid lesions.
