Bone scintigraphy and postoperative ureteropelvic urine extravasation

A case of severe urinary extravasation after renal pyeloplasty resulted in symptoms strongly suggestive of musculoskeletal origin. Bone scintigraphy revealed no findings relating to the skeletal system, but because of renal excretion of the tracer, the cause of the postoperative pain was revealed. The value of bone scintigraphy as a urinary tract diagnostic screening tool is probably underrated, even though at least 15% of studies fortuitously detect abnormalities of the urinary tract.
