Sonography of Renal Transplant-Associated Complications: A Primer

The advent of renal transplantation has significantly improved the quality of life and mortality of patients with end-stage renal disease. Unfortunately, transplant-associated complications (TACs) are common and pose a significant risk to both the allograft and the patient. A major advancement in the care of transplant recipients is the implementation of renal ultrasound, which allows for a more detailed assessment of the renal allograft and facilitates the distinction of different TAC manifestations such as perinephric fluid collections, vascular disease, and parenchymal disease. A better understanding of the clinical and sonographic features of TACs will help guide TAC management and promote better outcomes for renal transplant recipients.
