Reliability of ultrasound screening of liver and kidney donors: a retrospective study

The reliability of abdominal ultrasound in screening liver and kidney donors was assessed by correlating ultrasound findings with the suitability of organs for transplantation as determined by direct examination of the organs. We evaluated 100 multiorgan donors (100 livers, 200 kidneys) during a 15-month period. Abdominal ultrasound showed the following results for liver and kidney, respectively: specificity, 95.6% and 98.9%; sensitivity, 62.5% and 66.6%; and accuracy, 93% and 97%. These results show that abdominal ultrasound is a valuable tool for determining suitability of organs for transplantation when the ultrasound findings are normal. When ultrasound findings are abnormal, further studies are necessary to determine the suitability of the organs for transplantation.
