Abstract

PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder
MATERIALS AND METHODS
From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups.
RESULTS
For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups.
CONCLUSIONS
There were no significant differences in renal function between the ileal conduit and ileal W neobladder.
