Ureteral complications in renal transplantation with more than one donor ureter.
BACKGROUND
The purpose of this study was to evaluate the ureteral complications of renal transplant recipients with more than one donor ureter


METHODS
Between 1967 and 1997, 19 patients (median age 34 years, range 6-62 years) received renal transplants from donors with more than one ureter. There were 18 donor organs with two ureters, and one patient underwent en bloc renal transplantation with four donor ureters. In nine patients, the ureters were implanted separately at the bladder dome according to the extravesical technique of Witzel, Sampson, Lich and Röhl. In 10 patients, we performed a modification of this extravesical technique according to Nghiem with a side-to-side anastomosis of the ureters before completing the ureteroneocystostomy.


RESULTS
After a median follow-up of 55 months (range 2-218 months), no graft loss due to ureteral complications was noted. One patient died due to myocardial infarction, seven patients returned to dialysis without ureteral complications. There were two patients (one patient after side-to-side ureteral anastomosis, one patient with separate implantation of the two ureters) with ureteral obstruction of one donor ureter. Both patients underwent open surgical revision with temporarily placement of internal ureteral stents.


CONCLUSIONS
The presence of multiple ureters from donor kidneys is associated with a higher complication rate in our patient population compared with donor kidneys with one ureter. There was no difference in the long-term outcome between the two implantation techniques used.
