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 37 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 Rohl, 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 as 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 for
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. Key words: renal transplantation; ureter;
ureteroneocystostomy
