Kidney transplantation has changed dramatically over the past decade. Many advances have occurred that result in shorter hospital stays, decreased acute rejection, less infectious morbidity, and improved long-term allograft survival. Many factors are responsible for the improvement in kidney transplantation, and these factors are discussed in this review. These successes have led to a paradox in the care of the kidney-transplant recipient, however. As the short-term complications are prevented or successfully managed, more patients will develop chronic problems with the function of the allograft.
