Duplicated Ureters in Transplantation-A Single-center, Retrospective Study.

BACKGROUND

Kidney transplantation remains the best therapeutic option for chronic renal failure. The objective of the study was to evaluate the impact of ureteral duplication in donor kidneys on transplantation outcome.

METHODS

In this study we performed a retrospective analysis of 75 patients who had undergone renal transplantation. The evaluated parameters included frequency of occurrence and risk of reoperation and graftectomy, mortality, as well as dependency of early and long-term graft function on pyelocaliceal system duplication.

RESULTS

Ureteral duplication was associated with more frequent double J stent catheter implantation (P < .05). There was no relationship detected between ureteral duplication, number of operations performed, and risk of graftectomy (P > .05). Early graft function with 2 ureters was similar to that of grafts with a single pyelocaliceal system. The long-term results were also comparable.

CONCLUSION

Ureteral duplication should not be considered a contraindication for renal transplantation.
