Abstract:
A plain abdominal X-ray film (simple abdomen or KUB) is often used to display several types of urinary stones in vivo, or at least for a differentiation between calcium-containing 'radio-opaque' 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 lumbar vertebra or lower renal pole parenchyme were measured in each 20 patients with renal stones above 1cm in diameter and variable compositions. However, such a definite distinction could not be resulted in our study. Therefore, we think that it is not possible to achieve a predictability of stone composition by measuring of its radiodensity on KUB film.
