Delayed images of glucoheptonate distribution after renal transplant

Thirteen consecutive patients who had undergone renal transplantation were scanned 24 hours after glucoheptonate injection to document the incidence of gastrointestinal activity mimicking urinary extravasation. In six of the 13 patients, the activity was clearly within the small bowel or the colon but, in seven patients, the activity was noted surrounding the renal allograft. Using scintigraphy alone, it could not be determined whether this appearance represented cecal activity or urinary extravasation.
