title: Ureteral endometriosis: a complication of rectovaginal endometriotic (adenomyotic) nodules.
abstract: OBJECTIVE
  To present data from 18 cases of ureteral endometriosis.
  
  
  METHODS
  Prospective clinical study.
  
  
  METHODS
  Department of gynecology at a university hospital.
  
  
  METHODS
  Four hundred and five patients with severe dysmenorrhea or deep dyspareunia due to a rectovaginal endometriotic (adenomyotic) nodule.
  
  
  METHODS
  Patients were prospectively evaluated using intravenous pyelography. All patients underwent laparoscopic surgery to remove rectovaginal adenomyosis and ureterolysis.
  
  
  METHODS
  Presurgical and postsurgical evaluation and histologic analysis.
  
  
  RESULTS
  Preoperative intravenous pyelography revealed ureteral stenosis with ureterohydronephrosis in 18 patients (4.4%). A significantly higher prevalence (11.2%) was observed in nodules > or = 3 cm in diameter. Five women (20%) had complete ureteral stenosis. Kidney scintigraphy revealed damaged kidney parenchymal function, which ranged from 18% to 42%. Laparoscopic ureterolysis was done in 16 women; 2 women underwent ureteral resection and uretero-ureterostomy. A significant postoperative decrease in ureterohydronephrosis was noted in all patients; however, renal function improved only slightly.
  
  
  CONCLUSIONS
  Ureteral endometriosis was found in 4.4% of patients with rectovaginal endometriotic (adenomyotic) nodules. Ureterolysis and removal of associated adenomyotic lesions was sufficient therapy in most patients; two required resection of the ureteral stenotic segment. Intravenous pyelography should be performed in all women with rectovaginal nodules > or = 3 cm to prevent nonreversible loss of renal function.
