Arteriovenous malformation causing obstructive uropathy: A different dimension to ovarian vein syndrome

Ovarian vein syndrome is defined as obstructive uropathy caused by dilated ovarian vein with or without thrombosis. This is seen in the puerperal period as an acute condition with abdominal pain and fever and in multipara women with chronic recurrent abdominal pain. We report an ovarian vein syndrome caused by a true vascular anomaly in an 8-year-old child. Laparoscopic ureterolysis was performed with ligation of the arteriovenous malformation during the first operation. As ureterolysis was not effective, the patient was reoperated and ureteroureterostomy was performed after 3 months, which emphasizes the importance of removing the diseased segment even if it looks normal.
