Radiographic features of ureteral endometriosis.

The urographic findings in seven patients with ureteral endometriosis were reviewed. These consisted of short strictures (0.5-2.2 cm) located for the most part in that portion of the pelvic ureter projected within 3 cm of the inferior margin of the sacroiliac joint. Although the appearance is judged to be nonspecific, the diagnosis of ureteral endometriosis should be considered in any female patient of child-bearing age who has obstructive uropathy attributable to extrinsic obstruction of the pelvic portion of the ureter.
