The Predictability of Stone Composition According to the Radiodensity of Urinary Stone on KUB Film

Abstract
|
|
|
A plain abdominal X-ray film 9simple abdomen or KUB) is often used to display several types of urinary stones in vivo, or at least for a differentiation between calcium-containing 'radioopaque' and calcium-noncontaining 'non-opaque' stones.
We evaluated whether a KUB film could offer the information on composition of urinary calculi or not. The radiodensity of stone itself, the ratio of radio-opacity between the stones and the 2nd lumbarvertebra or lower renal pole parenchyme were
measured
in each 20 patients with renal stones above 1 cm in diameter and variable compositions. Howver, such a definite distinction could not be resulted inour study. Therefore, we think that it is not possible to achieve a predictability of stone
composition
by measuring of its radiodensity on KUB film.
