Experiences and Outcomes of Inverted Kidney Transplantation From a Single Vietnamese Institute

Abstract

Background Inverted kidney transplant (KT) have been applied in many transplant centers, but the experiences and outcomes of this technique was limited. Aim To describe the technical characteristics, indications and evaluate the outcomes of inverted kidney transplantation. Methods Retrospective study from January 2016 to December 2023, included 74 patients who underwent inverted kidney transplantation with 72 cases of right kidney transplant into the right iliac fossa and 2 cases of left kidney transplant into the left iliac fossa performed in Viet Duc University Hospital. Results 63 cases in stage 1 (ipsilateral kidney transplant), all kidney graft were transplanted on the same side and 11 cases in stage 2 in which the kidney transplant was performed in some special cases such as recipients with severe atherosclerotic iliac arteries or incompatibility between the arteries and venous. There was 1 case (1.4%) of graft renal artery pseudoaneurysm and 5 cases (6.8%) of ureteral stenosis at the ureter-bladder junction. There was 1 case of graft loss due to chronic graft rejection – immunosuppression inadherence requiring retransplantation after 2 years. 98.6% of cases had normal kidney function when discharged and remained stable until the latest follow-up. Conclusion Inverted kidney transplantation is a simple, safe and effective technique and could be a feasible solution for atherosclerotic patients.
