Abstract

BackgroundMultiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft.ObjectivesTo find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries.Patients and MethodsWe analyzed 147 kidney transplantations, (all performed in our hospital over a 3 year period). population divided into two groups: group A for those who presented with only one renal artery, or group B for those with more than one renal artery. Homogeneous vascular reconstructions and implantation rules were applied in all patients. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of post-transplantation.ResultsNo significant differences were found between the two groups regarding to the values analyzed.ConclusionsAs many other authors, we do believe that the presence of multiple renal arteries in kidney grafts should not be considered as a predictive factor of transplantation failure.

Highlights

  • Multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications

  • We evaluated all of cases, including those grafts that were rejected for some reason at the time of the implantation

  • Harrison et al revised arteriographies of future living-donors and concluded that 25% of people had multiples arteries and less than 50% of them had the simplest form of renal vascular pedicle [5]

Summary

Introduction

Multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft. Objectives: To find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of posttransplantation. Kidney transplantation is the best treatment for most of these patients and the number of patients who are waiting for a graft is rising [2]. Do we really believe those multiple-arteries grafts will have a poorer outcome?
