Graft Kidney Torsion After Simultaneous Kidney-Pancreas Transplant: Report of 2 Cases and Literature Review

摘要

Anumber of complications can occur after kidney transplantation, including postoperative hemorrhage, transplant artery or vein thrombosis, urine leak, ureteral stricture, and rejection. Al-lograft torsion is an extremely rare and potentially reversible complication in which the kidney rotates around its vascular pedicle, compromising the vascular supply. Allograft torsion is difficult to diagnose because no specific set of clinical features exists. Presentation typically mimics other more common causes oftransplant dysfunction such as rejection, ureteral obstruction, or vascular stenosis or thrombosis. The diagnosis of kidney allograft torsion is frequently delayed because of its nonspecific presentation, even if prompt imaging is performed. Although immediate diagnosis and surgical intervention can salvage allograft function, delayed diagnosis can lead to vascular occlusion and parenchymal infarction, with resulting graft loss. This report describes 2 cases of kidney allo-graft torsion occurring in intraperitoneal grafts after simultaneous kidney-pancreas transplantation.
