Evolution of a ureteric stone from the renal pelvis to the ureter on skeletal scintigraphy with CT correlation.
Because bone-seeking radiopharmaceuticals are excreted into the urine by the kidneys, normal kidneys and bladder are well visualized on skeletal scintigrams leading to incidental detection of urinary tract abnormalities in up to 15% of bone scans. Although the findings pertaining to the urinary tract on skeletal scintigraphy are seldom suggestive of a definitive diagnosis, they are highly specific for renal disease, with fewer than 2% false-positive studies reported. In the presented case, we demonstrate the evolution of a ureteric stone from the renal pelvis into the ureter on sequential skeletal scintigraphy with CT correlation.
