OP14.09: Symptoms and sonographic findings of women with bladder endometriosis

To describe symptoms and sonographic findings of women with bladder endometriosis (BE). A prospective study including patients with ultrasound diagnosis of BE who attended an Endometriosis Unit were included. The infiltration of the nodules was described by TVUS (RIC5-9, Voluson V730Expert, GE): nodules affecting anterior cul-de-sac and partially the detrusor were classified as less infiltrative (Group 1), while more infiltrative nodules (affecting completely the detrusor with bladder protrusion) were classified as Group 2. Ureteral meatus, signs of hydronephrosis (abdominal) and other focus of pelvic endometriosis were also collected. The degree of symptoms (dysuria, dysmenorrhea, dyspareunia, pelvic pain, dyschezia) was evaluated using VAS (0-10). Severity of symptoms and association with other types of endometriosis were compared between groups. From 2016 to 2018, BE was identified in 22 patients of a total of 2207 women (1%), with a mean age of 35,8%±6.7 years old. TVUS identified 9 nodules of Group 1, and 13 nodules of Group 2. Ureteral meatus were visualised in 20/22 women. Only 4 women had hydronephrosis due to retrocervical nodules. 14 patients reported dysuria (63%) with the mean severity of 1±2.7 in Group 1 and 5.7±3.5 in Group 2 (p = 0.0004). No statistically significant differences were found in the rest of symptoms. Only 4 patients reported haematuria (3 with infiltrative nodules). Up to 17/22 patients had adenomyosis (7 in the anterior wall). Up to 11/22 women presented endometriomas, 13/22 rectosigmoid, 15/22 retrocervical and uterosacral, 8 vaginal endometriosis, 17 ovarian fixity and 11 a negative sliding sign. No differences were observed between groups in the location of other types of endometriosis. Women with more infiltrative nodules referred more dysuria than women with nodules that not protrude in the bladder cavity. Women with BE had frequently associated other types of endometriosis. Bladder nodules do not usually affect ureteral meatus and do not frequently cause hydronephrosis.
