Complication with mechanical stapling device in creation of ileoconduit.

Of 296 patients with pelvic malignancy and ileal urinary conduits, urinary tract calculi developed in 14. Calculi which ordinarily require surgical intervention because of their size may pass spontaneously in patients with ileoconduits because of the presence of a chronically dilated colllecting system and the surgical elimination of three of the four sites of stone impaction (pelvic brim, ureterovesical junction, and ureteral orifice). In 1 patient multiple calculi developed around the surgical staples used to create the proximal end of the ileal conduit. We recommend that autosuture with stapling devices not be used to create the proximal end of an ileal urinary conduit.
