  • Title: The detection of pyelonephritic scarring in children by radioisotope imaging.
    Author: Merrick MV, Uttley WS, Wild SR.
    Journal: Br J Radiol; 1980 Jun; 53(630):544-56. PubMed ID: 7426865.
    Abstract:
    Radioisotope scintigraphy of the kidney and intravenous urography have been compared in 79 children with bacteriologically proven urinary tract infections, followed up over a period of between one and four years. Both techniques were in agreement as to the presence or absence of an abnormality, and the extent of any abnormality present, in 93.5% of the kidneys studied. There was a discrepancy in ten kidneys. Excretion urography has a sensitivity of 0.86 and a specificity of 0.92 in the detection of pyelonephritic scarring in children. Radioisotope scintigraphy has a sensitivity of 0.96 and a specificity of 0.98. It is therefore concluded that radioisotope scintigraphy is the preferred technique.
