Endometriosis of the ureter and bladder are not associated diseases

Abdominopelvic Complications of Endometriosis

“…Generally, bladder is not affected for endometriosis in the patients with ureteral endometriosis. This observations confirms that, although ureter and bladder are both part of the urinary tract, endometriotic lesions affecting these sites have a different behavior (Abrao et al, 2009). …”

“…The bladder is the most frequently involved organ, followed by the ureters and the kidneys with a proportion of 40:5:1. The endometriosis that comprises the urinary tract cannot be considered to be primary lesions from these organs (Abrao et al, 2009). …”

“…Patients may present with variable urinary symptoms (cystalgia 43%-58.3%, dysuria 21%-25%, urinary frequency 16.6%-71%, macroscopic hematuria 12.5%-19%) (Le Tohic et al, 2009) and/or symptoms related to endometriosis (dysmenorrhea 70.8%, dyspareunia 21%-50%, chronic pelvic pain 43%-75%); these symptoms may be cyclic (34.6%-100%) (Abrao et al, 2009;Le Tohic et al, 2009). This entity should also be considered in postmenopausal patients receiving hormonal replacement therapy who report voiding symptoms and who are unsuccessfully treated for interstitial cystitis.…”

“…Ureteral endometriosis is a rare but serious localization of the disease (<0.3%) (Li et al, 2008) because it may cause silent loss for renal function (Abrao et al, 2009;Li et al, 2008;Mereu et al, 2010). Disease is predominantly unilateral, with the left ureter affected more commonly than the right, although bilateral disease does occur (Li et al, 2008).…”

“…Disease is predominantly unilateral, with the left ureter affected more commonly than the right, although bilateral disease does occur (Li et al, 2008). The lesions are localized in the lower third of the ureter (Abrao et al, 2009), and associated with endometriosis elsewhere in the pelvis (Li et al, 2008;Mereu et al, 2010). There are two major pathologic types of ureteral endometriosis: intrinsic and extrinsic, occurring, respectively with a 1:4 ratio.…”
