[Significance of kidney and urinary tract abnormalities detected during bone scintiscans (author's transl)]

The kidneys and the bladder are regularly visible when bone scintiscans are performed during 99mTc-labelled phosphorus compounds, and abnormalities in the distribution of local activities within these organs are not uncommonly detected. The authors were able to compare such abnormalities with clinical, laboratory and X-ray data in 139 out of 1980 cases of bone scintiscan. In 84% of the cases the pathological image was associated with an established renal or urinary disease and was indeed often responsible for its unexpected discovery. Urinary tract abnormalities detected on bone scintigrams therefore deserve to be taken into consideration and should be confirmed by appropriate investigations.
