Modified autosuture technique for ileal conduit construction in urinary diversion

The autosuture stapling technique in ileal conduit formation is modified to exclude the proximal staple line from the urinary stream, so as to prevent calculus encrustation on the staples. We have also selected the open-lumen technique of bowel anastomosis, rather than the closed-lumen technique, and have found no increase in complications with this method. In particular, no problems with excessive faecal contamination were encountered.
