We wish to report on some of the more interesting experiences we have had with the use of the ileocecal-ascending colon type of substitute bladder. The operative technique has been previously described.1,2 Most of the ureteral implants have been done by a modified Coffey I method. Some anastomoses were made by the combined mucosa-to-mucosa and tunnel technique We are now spatulating the end of the ureter (Fig. 1). Then the end of the ureter is drawn into the new bladder a short distance by two sutures (Fig. 2). The final position of the ureters in the bladder is shown in an open view of the bladder (Fig. 3). The completed anastomosis (on the right side only) is shown in Figure 4, before the left side has been transplanted and before the bladder has been tacked down over the brim of the pelvis. The ureteral transplantation is done as the
