Suboptimal kidney: the experience of a single transplant unit

Abstract

Not all kidneys are suitable for transplantation. In 2001 in Italy, only 1530 of 1748 organs were transplanted. This difference (-12.5%) not only represents organs harvested from marginal donors considered not suitable, but also kidneys that, although collected from standard donors, had a vascular, parenchymal, or urologic anomaly that made them unsuitable for transplantation. In our center, we established a procedure that defined the characteristics of suboptimal kidneys and allowed us to specifically select the appropriate recipient. We considered as suboptimal all organs with complex arterial anomalies (more than 2 arteries although on a single patch or separated such as to need a double anastomosis or a bench reconstruction); organs with noticeable parenchymal damage (macroscopic sclerosis areas or sutured polar branches accidentally damaged during removal), and organs with complex anomalies of the excretory tract (complete double district). The organs were not considered as suboptimal if they had venous anomalies revised on the bench or if they had a double artery with a single patch <2.5 cm. Such organs were transplanted to recipients who were between 55 and 60 years of age with a body weight of at least 20% less than the donor, and female
