Abstract:
Ureteral endometriosis (UE) can be classified as severe when there is obstruction to urinary flow (ureteral compression (UC)). In this retrospective study on 205 patients, we evaluated intraoperatively the frequency of severe ureteral endometriosis (UE) in women with UE and, secondarily, risk factors associated with UC. We documented intraoperatively ureteral UC in 124 (60.5%) patients with UE. A significantly lower body mass index (BMI) was observed in women with UC than in women without UC (p = .02). A significant association was found between UC and parametrial endometriosis (p = .001). In multivariable analysis, these variables remained significantly associated with UC. Ureteral compression is common in patients with UE, especially in women with parametrial infiltration and a low BMI.

Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
