Two cases of spontaneous ureteral rupture secondary to outlet obstruction.
Two patients with outlet obstruction and spontaneous extravasation of contrast material from their ureters during an intravenous urogram (IVU) are reported. Both cases are unusual in that spontaneous ureteral extravasation is rare and usually occurs with calculus disease. These patients had no evidence of calculi; therefore, the increased intraluminal pressure alone appears to have caused ureteral rupture.
