A comparative study of the ileal conduit, Kock pouch and modified Indiana pouch

Between July 1986 and July 1988, 55 urinary diversions were performed, including 18 ileal conduits, and 12 Kock and 25 Indiana pouch procedures. The different forms of urinary diversion were compared for patient selection, operative technical demands, postoperative complications, perioperative renal function and short-term followup, including rehospitalizations, revisions and pouch function. Patient selection was the same for the ileal conduit and Indiana pouch groups. Kock pouch patients were more highly selected for youth and health status. The operative technical demands of the ileal conduit and Indiana pouch were similar. The average operative time and blood loss for cystectomy and ileal conduit were 5 hours 27 minutes and 1,290 cc versus 5 hours 30 minutes and 1,201 cc for the Indiana pouch group. Postoperative complications and changes in renal function were similar among all 3 groups except for an increase in urinary anastomotic leaks in heavily irradiated ileal conduit patients. The ileal conduit patients required no rehospitalizations or revisions, the Indiana pouch group had 4 rehospitalizations and no revisions, and the Kock pouch group had 9 rehospitalizations and 3 revisions. The day and nighttime continence rate was 100% in the Indiana and Kock pouch groups. The Indiana pouch has similar technical demands as the ileal conduit, similar postoperative complications as the ileal conduit or Kock pouch, and functions well with a low revision rate. We conclude that the modified Indiana pouch can be accomplished safely and effectively in any patient requiring an ileal conduit.
