Ureteral obstruction by uterine artery aneurysm in third trimester of pregnancy.

ABSTRACT

Uterine artery aneurysm (UAA) is an uncommon complication of pregnancy. Its diagnosis before postpartum hemorrhage is rare. We report on a patient who presented with symptomatic ureteral obstruction secondary to UAA. The hydronephrosis was managed by ureteral stenting. The UAA was successfully embolized after a planned cesarean section delivery. UAA is a rare and clinically significant cause of hydronephrosis during pregnancy.
