Nephroptosis Incidentally Found on 99m Tc-DTPA Renal Dynamic Scan

Keshan Wang et al. Clin Nucl Med. .

Abstract

Nephroptosis is a significant descent (more than 5 cm or 2 vertebral bodies) of the kidney from supine to the upright position. The incidence of nephroptosis is probably more prevalent than reported, as few patients present with typical symptoms. A 55-year-old woman with intermittent abdominal pain was referred for a 99m Tc-DTPA renal dynamic scan. She had a ureteric calculi history. The result showed that the right kidney was significantly lower than the position in the CT scan a week ago. It had been diagnosed as nephroptosis according to these "moving" images. She was considering elective surgery for intervention.
