Extrarenal scintigraphic aspects of kidney transplant scans obtained with 99mTc-DTPA.

In a retrospective study, 300 scans obtained with 99mTc-DTPA of 100 kidney transplant recipients were studied. The aim was to look for extrarenal scintigraphic aspects encountered specifically in renal transplant scintigraphy and to determine whether some of these phenomena could interfere with adequate interpretation. The most important phenomena seen were radioactivity in the uterus and a cold spot in the pelvis minor caused by a urine filled bladder. If the phenomena that can be encountered are known, the risk of incorrect evaluation is small. In addition, we report on the occurrence of stasis due to disturbed urine flow.
