Abstract

PURPOSE: This report presents our experience of the renal transplatation of a long term dysfunctional contracted bladder and its outcome.
METHODS
Between March 1996 and May 2006, 425 cases of renal transplantation were performed in our medical center. We found 14 chronic renal failure patients having dysfunctional contracted bladder (DFCB) that was diagnosed through the preoperative voiding cystourethrogram. DFCB was defined as the maximal urinary bladder volume less than 100 mL. No surgical or medical preparation was done before and after renal transplantation. In 8 out of 14 cases, extravesical ureteroneocytostomy (EVUC) was conducted and the Lich's EVUC was done for the other 6 cases. Double J ureteral stent was not employed in any cases.
RESULTS
The mean age of the recipients was 41.4 years. The mean capacity of these bladder was 72.1 mL (range 20 to 100 mL). Of the 14 cases, thirteen had living donor related transplantation and one received cadaveric kidney. Postoperative complication was occurred in one case, which was bleeding. There was no evidance of urinary tract complication. All patient excluding of one patient who had the episodesof chronic rejection were stable throughout the entire follow up period.
CONCLUSION
DFCB in renal translpantation had no adverse effect on successful outcome in transplant operation deposite no preoperative preparation, especially cadaveric donor transplatation, it may, however, need a delicate surgical skills to perform EVUC.
