[Intrinsic endometriosis of the ureter]

Two cases of ureteral endometriosis are reported and the literature is reviewed with special emphasis on symptoms and therapy. New diagnostic methods such as computer assisted tomography, ultra-sonography and urinary cytology are discussed and evaluated. Intrinsic ureteral endometriosis should be treated with local resection, and reimplantation with the psoas-hitch technique. The need for post-operative hormonal management must be adapted to each case.
