Renal parenchymal scars in adults. Split function and extent of scars at urography and DMSA scintigraphy

In 13 adult patients the occurrence of renal scars was evaluated, and the split function was determined at both intravenous urography and 99mTc DMSA scintigraphy. The split function was also measured by the gold standard - hippuran renography. DMSA scintigraphy turned out to be as good as intravenous urography for evaluation of established scars and better for determination of split function. Thus, scintigraphy may replace intravenous urography in adults with symptoms or signs of renal scars.
