Infrared spectroscopy in the assessment of the mineral composition of kidney stones

Abstract

As a result of infrared spectroscopy of kidney stones obtained from 59 patients with urolithiasis, a wide range of chemical compounds were identified in the samples, in which whevellite (calcium oxalate monohydrate), hydroxylapatite and uric acid were presented in the largest quantities. Monophasic stones were found in 8.4 % of patients. The two-phase, three-phase and four-phase composition of the samples was determined in 37.2 %, 42.3 % and 11.8 % of patients respectively. Carrying out infrared spectroscopy of kidney stones obtained as a result of self-passage or due to the use of surgical methods will contribute to the correct choice of an individual program for metaphylaxis of urolithiasis in different patients.
