[Omentoplasty and a temporary internal stent in the treatment of recurrent peri-pyelo-ureteritis. Surgical technic. Apropos of a case].

Repetitive surgery on the upper urinary tract calls for extensive and sometimes difficult dissection, therapy exposes to the risk of vascular and nervous injury, as far as tissue trophism is concerned, moreover to secondary severe perivisceral fibrosis. The ureter is particularly liable to such early or late damages. The use of a self-retaining stent, even for a long period of time, and of a pedicle omental graft wrapping ensures a better recovery and the prevention of fistulae or strictures from secondary retroperitoneal fibrosis.
