Abstract:
To make a right choice of a treatment approach in patients with nephrolithiasis it is very important for the clinicians to know the composition and structure of calculus. Conventional radiographic techniques and computerized tomography (CT) give information about the location and size of concretions, but not for their composition and structure. In the present study we investigated the gray-level values of chemical substances in concretions. It was established the appropriate X-ray exposure for subsequent image analysis. A method for intracorporal analysis of composition and structure of kidney concretions is proposed.
