title: Right ovarian vein syndrome. A case with pre- and peroperative electromyographic registration of ureteral activity.
abstract: Electrophysiological studies of ureteral function in a patient with right ovarian vein syndrome demonstrated intermittent antiperistalsis as reflected from pre-operative endoureteral activity recordings. The antiperistalsis was related to the patient intermittent right flank pain. Per-operative EMG and pressure measurements revealed that the antiperistalsis apparently arose from the area of obstruction and caused pressure waves of higher amplitude than those seen during normal anterograde peristaltic activity. After section of the vein, exclusively anterograde peristalsis was observed, and at 3 month follow-up, the patient was free of right side colics.
