title: Duplication of the inferior vena cava in retrocaval ureter. A case of peroperative urodynamic investigation.
abstract: A patient with partial duplication of the inferior vena cava and a retrocaval ureter was preoperatively studied by uro-cavography and renography. Peroperatively intrapelvic pressure measurements were made, and simultaneous EMG recordings were taken from the pelvis, and from the ureter proximal and distal to the retrocaval segment. The electrophysiological activity was normal with normal anterograde impulse transmission. Renal pelvic pressure and pressure increase during forced diuresis was within a normal range.
