Urologic Complications After Transplantation of Kidneys With Duplicated Ureter: A Retrospective Study

Transplant Proc. 2019 Apr;51(3):779-782. doi: 10.1016/j.transproceed.2018.10.030. Epub 2019 Jan 9.

Abstract

Background: Duplication of ureters is a common anatomic abnormality and occurs in 0.7% to 1% of the general population. In this article we focus on the safety of using of kidneys with complete ureteral duplication, provided no hydronephrosis or ureterocele was present in the donor.

Methods: From 1998 to March 2018 there were 1965 kidneys transplanted at our institution, including 27 kidneys with duplicated ureter, which corresponds to incidence of 1.4%. Patients' medical records, surgery protocols, and Poltransplant registries were searched for urinary complications.

Results: In the double ureter group, urologic complications occurred in 4 patients (15.4%). Similarly, severe urinary complications developed in 4 patients from the control group (17.4%).

Conclusions: Transplantation of kidneys with duplicated ureters appears to be a safe and feasible procedure.
