Inflammatory ureteral strictures after ureteroileal diversion

We describe 2 patients in whom histologically proved inflammatory strictures of the ureter developed after ureteroileal diversion. The dense impassable strictures were located proximal to the ureteroileal junction. The clinical onset was preceded by acute urosepsis and septicemia. Judicious use of percutaneous nephrostomy and antegrade studies is emphasized in establishing the diagnosis.
