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 99mTc-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. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
