Ureteral stenting via an ileal conduit using a gastroscope.

Abstract

We describe a technique that facilitates retrograde ureteral cannulation and stenting in patients with an ileal conduit. A standard flexible gastroscope is inserted into the ileal conduit. Guide wires are passed into the ureters under direct vision. Stents are inserted over the guide wires with the aid of the image intensifier. The technique was used repeatedly in 1 patient with a complex history who had ureteral strictures. The procedure is technically easy and it was successful on each occasion. A fiber optic gastroscope may have advantages over conventional urological instrumentation for inserting ureteral stents in patients with an ileal conduit. This novel, simple technique is less invasive than percutaneous stenting and easier than fluoroscopic cannulation of the ureters. It is readily repeated.
