[Current status of continent urinary reservoirs for invasive bladder cancer patients undergoing total cystectomy].
Continent urinary reservoirs (CUR) have become one of the major options of urinary diversion for invasive bladder cancer patients who require cystectomy and cutaneous urinary diversion. We have experienced 100 cases of Kock pouch and 30 cases of indiana pouch during the past 5 years which comprise 45% of all cases. Standard ileal conduit and ureterocutaneostomy were performed in 34% and 20%, respectively, and orthotopic urinary reservoir by hemi-Kock pouch was done in only one case during the same years. There were 3 perioperative deaths, 2 had Kock pouch and one Indiana pouch. Early postoperative complications were not substantial. However, significantly high rates of late postoperative complications were seen in Kock pouch, i.e., both efferent (18%) and afferent (13%) nipple valves and stone formation (18%). Uretero-ileal anastomosis by hammock method done in 10 cases resulted in success in 8 cases, abolishing the afferent nipple. Indiana pouch, in which no nipple valves or foreign materials like staples or collars are necessary, has been adopted as a first choice for the past 3 years. Of 29 evaluable cases, Heineke-Mikulicz method was used in 7 cases, and ileal patch method in 22 cases. An hourglass-like deformity was seen in 2 cases in the former method. Severely difficult catheterization, parastomal abscess, and acidosis occurred in one. Overall, 24 cases (83%) have come up with satisfactory results with minimal overflow incontinence in the early postoperative course. Although much longer followup is necessary, CUR's by Kock or Indiana pouch are more acceptable by bladder cancer patients requiring cystectomy.
