Tc-99m MAG3 evaluation of recipients with En bloc renal grafts from pediatric cadavers.

Tc-99m MAG3 scintigraphy is a well-established test to monitor patients who have received renal grafts. The shortage of available kidneys has forced the development of alternative sources of donors. En bloc pediatric renal grafts have been used for more than 10 years with good results, but mechanical complications are still a concern. No reports have illustrated the Tc-99m MAG3 scintigraphic aspect of the most common complications resulting from en bloc pediatric renal grafts. The authors describe three recipients of en bloc renal graft. One patient had thrombosis of one of the two grafts, one patient had postrenal obstruction of only one of the grafts, and a third patient progressed normally.
