Abstract
Thirteen patients who had undergone renal transplantation were scanned 24 h after glucoheptonate injection to document the incidence of gastrointestinal activity mimicking urinary extravasation. In 6 of the 13 patients, the activity was clearly within the small bowel or the colon but, in 7 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.
