December 3, 2023 updated by: Radboud University Medical Center

The Optimal Method for Ureter Implantation in Pediatric Kidney Transplantation

In this study the researchers want to retrospectively compare non-refluxing ureteroneocystostomy (UNC techniques to reflux UNC techniques in paediatric kidney recipients with regard to urinary tract infections and uteral obstruction.

Detailed Description

Multi-center retrospective study and survey on clinical practice among different urologists. The researchers will retrospectively study data on patients that received their kidney graft between 1994-2018 in either Radboudumc or UW Health University Hospital in Winsconsin.

Additionally, all urologist currently employed at those hospitals will be asked to fill in a survey on preferences in UNC techniques and suture material.
