title: The use of danazol for ureteral obstruction caused by endometriosis.
abstract: We report 2 successfully treated cases of unilateral obstruction owing to endometriosis. Treatment consisted of danazol alone in 1 case and surgical freeing of the obstructed ureter in the other. Danazol alone can reverse completely ureteral obstruction caused by endometriosis but if secondary fibrosis has occurred surgical treatment may be necessary. This is the first case reported of complete resolution of unilateral ureteral obstruction owing to endometriosis using danazol therapy alone.
