Highlights
- •Description of symptoms and locations of 232 cases of urinary tract endometriosis.
- •Ureteral endometriosis was significantly associated with other DIE lesions.
- •Ureteral endometriosis was more often asymptomatic than bladder locations.
Abstract
Objective
To review prospectively the clinical characteristics of patients suffering from urinary
tract endometriosis (UTE) in France, in 2017.
Study design
We conducted a prospective observational multicenter study including women managed
surgically for UTE in 31 French endometriosis expert centers (FRIENDS group) from
January 1, 2017 to December 31, 2017. We distinguished patient with isolated bladder
endometriosis (“IBE”) or isolated ureteral endometriosis (“IUE”) and patients associating
both locations (mixed locations “ML”). Surgeons belonging to FRIENDS group enrolled
patients by filling a 24 items questionnaire the day of the surgery and 6 weeks later.
Data on the locations of UTE, preoperative assessment, urinary symptoms and associated
pelvic locations were collected in a single anonymized database.
Results
A total of 232 patients from 31 centers were included. IBE concerned 82 patients (35.3%),
IUE 126 patients (54.4%) ML 24 patients (10.3%). 111 patients reported urinary symptoms
(47.8%). IUE was more often asymptomatic than the rest of the locations (59.5% versus
43.3%, OR 1,92, p = 0.017). Associated deep infiltrating endometriosis (DIE) lesions
were found in 193 patients (83.1%). IUE was significantly associated with other DIE
lesions (82.5% versus 66%, OR2.4, p = 0.006), particularly with rectum or sigmoid
nodules (57.1% versus 36.8%, OR 2.3, p = 0.002) and retrocervical space nodules (31.7%
versus 19.8%, OR 1.9, p = 0.05).
Conclusion
Our study reports the second largest series of patients operated from a UTE and shows
that ureteral location seems more frequent, less symptomatic and more frequently associated
to other DIE locations than bladder endometriosis.
