[Pancreatitis: a little-known cause of ureteral obstruction].

Left ureteral stenosis induced by pancreatitis was observed in one case. Five similar cases have been reported in the literature. Ureteral obstructions may be found in two clinical contexts--patent pancreatitis or retroperitoneal fibrosis. The ureter may be simply compressed mechanically, or there may also be enzymatic or ischemic necrosis. The clinical approach should be directed towards treating primarily the pancreatitis and secondarily the urological pathology. As regards the urological treatment, ureterolysis or ilio-ureteroplasty are indicated in cases of organized irreversible ureteral stenosis.
