title: Unfriendly Filter: An Unusual Cause of Hydronephrosis and Hematuria.
abstract: A 67-year-old woman was referred to the urology clinic for abdominal pain and hematuria. Urine analysis showed microscopic hematuria. Computed tomography urogram revealed a misplaced inferior vena cava (IVC) filter in the right gonadal vein causing right hydronephrosis. Retrograde pyelography revealed a 3-cm ureteral narrowing at the level of the IVC filter. A double-J ureteral stent was placed in the right ureter prior to exploratory laparotomy, which revealed partial erosion of the IVC filter into the right ureter and a thrombosed right ovary. The patient underwent a right oophorectomy and removal of the misplaced IVC filter. Her postoperative course was uncomplicated.
