Modified extravesical ureteroneocystostomy for completely duplicated ureters in renal transplantation.
BACKGROUND
Completely duplicated ureters are the most common congenital malformation of the upper urinary tract. However, there are very few reports on transplantation using kidneys with double ureters, and the technique of ureterocystoneostomy for completely duplicated ureters has not yet been established.


METHODS
We treated 3 patients with completely duplicated ureters at our institutions from January 1998 to October 2005. We modified the extravesical technique for treating these 3 cases and evaluated the 52-month follow-up period for possible urological complications.


RESULTS
Neither urological complications nor urinary tract infections occurred in the follow-up period after using our new technique.


CONCLUSIONS
We conclude that this technique is an appropriate procedure for the transplantation of kidneys with completely duplicated ureters.
