  • Abstract
  • Look Inside

Retrospectively we estimate the usefullness and limitation of the indwelling double pigtail ureteral stent in 20 patients with the ureteral obstructions. They were devided in two groups, one group (6 cases benign group) with inflammatory changes and postoperative scars, and the other group (14 cases malignant group) with neoplastic invasion. In benign group, ureteral stent drained effectively except for one case of spontaneous disruption of ureteral stent. But in 7 of 14 cases in malignant group, ure-teral stent failed to drain effectively due to stent obstruction by necrotic tissue.
