Abstract:

Aim: was to evaluate possibilities of dual-energy multislice computed tomography (MSCT) in determining the composition of kidney stones.

Materials and methods: a dual-energy MSCT was performed in 60 patients with urolithiasis of different locations (63.3% male, 36.7% female). Two groups of patients were identified: with mixed (simultaneously, the patient was diagnosed with stones of urate and non-urate structure) and nonurate composition of stones. Out of 60 patients, 16 (10 patients from a mixed group and 6 from a

non-urate) were subjected to chemical analysis of stones by IR-spectrometry and X-ray phase analysis. Obtained data were compared with data of the dual-energy MSCT Results: in most cases (93,7 %), results of the chemical analysis of stones confirmed the structure of uroliths obtained by the dual-energy MSCT method.

Conclusions: The method of dual-energy multislice computed tomography is effective in determining the composition of stones of the urinary system, appears to be a promising method in the diagnosis of urolithiasis, and expands possibilities of modern urology in planning patients with urolithiasis.
