[Obstructive endometriosis of the efferent urinary tract].

Even though, in every 7th to 8th patient with endometriosis, it occurs in the efferent urinary tract, little attention has been paid this fact, generally speaking. This may be due in part to the atypical symptomatology of ureteral or respectively vesical endometriosis. However, its consequences can be serious in both younger patients as well as postmenopausal women. On the basis of two of the authors' own cases and the literature, the clinical symptoms and treatment of vesical endometriosis and ureteral obstruction associated with pelvic endometriosis are discussed.
