Ureteroneocystostomy versus ureteropyelostomy: a comparison in the same renal allograft series

Of the 132 transplants in our series 44 patients underwent reconstruction by ureteropyelostomy (group 1) and 88 underwent reconstruction by ureteroneocystostomy (group 2). The rates of major urologic complications were 11 percent in group 1 and 4 per cent in group 2. These results support the widely held opinion that ureteroneocystostomy is the superior method for urinary reconstruction in renal allograft cases. However, the alternative of ureteropyelostomy should be part of every transplant surgeons' armamentarium, especially for cadaver transplants when ureteral blood supply may be compromised.
