Ultrastructural Analysis of Urinary Stones by Microfocus Computed Tomography and Comparison with Chemical Analysis
Journal Title: Dicle Tıp Dergisi - Year 2016, Vol 43, Issue 2
Abstract
Objective: To investigate the ultra-structure of urinary system stones using micro-focus computed tomography (MCT), which makes non-destructive analysis and to compare with wet chemical analysis. Methods: This study was carried out at the Ankara Training and Research hospital. Renal stones, removed from 30 patients during percutaneous nephrolithotomy (PNL) surgery, were included in the study. The stones were blindly evaluated by the specialists with MCT and chemical analysis. Results: The comparison of the stone components between chemical analysis and MCT, showed that the rate of consistence was very low (p<0.001). There was no significant relationship between the components of stone and its heterogeneity or homogeneity. No significant difference was found between the stones with single component and those with multiple components in terms of its 3D structure being homogenous or heterogeneous and the presence of voids (p>0.05). It was also seen that there was no significant relation between its 3D structure being heterogeneous or homogenous. Conclusion: The stone analysis with MCT is a time consuming and costly method. This method is useful to understand the mechanisms of stone formation and an important guide to develop the future treatment modalities. Key words: Computed tomography, micro, urinary stone analysis, urolithiasis
