title: Simplified technique with short and long-term followup of conversion of an ileal conduit to an Indiana pouch.
abstract: OBJECTIVE
  We report a simplified technique for converting an existing conduit to an Indiana pouch as well as short and long-term results.
  
  
  METHODS
  From May 1988 to February 1998 we evaluated short and long-term outcome and complications in 23 patients 14 to 82 years old (average age 51.8) who underwent conversion of a conduit to an Indiana pouch. When no obstruction of the existing ureteroileal anastomoses was identified, the conduit was freed from the abdominal wall and surrounding bowel. The proximal conduit and ureteral anastomoses were not dissected. The conduit was opened along the antimesenteric wall proximal to the ureteral anastomoses and attached to 25 to 28 cm. of detubularized right colon as a refluxing Studer limb. The pouch was completed in the usual fashion and the stoma was matured at a virgin site.
  
  
  RESULTS
  Surgical indications included stomal complications in 10 patients, an infected nonfunctioning kidney in 2 and patient preference in 11. There were no perioperative deaths although 3 patients died of cancer progression. Average operative time was 6.6 hours, estimated blood loss 518 cc and length of stay 7.8 days. Average followup after conversion was 4.7 years (range 0.2 to 11.0). Six late complications developed in 4 cases, including pyelonephritis in 2, severe pouchitis in 1, dehydration in 1 and stomal revision in 2. Renal function was well preserved with an average preoperative and postoperative creatinine of 0.91 and 1.14 mg./dl., respectively.
  
  
  CONCLUSIONS
  This technique simplifies conversion and decreases bowel requirements. The low complication rate and stable serum creatinine support the finding that conversion of a conduit to an Indiana pouch is a safe, viable procedure.
