[Mineralogical composition of urinary stones, risk factors and metabolic disturbances in patients with calcium-oxalate urolithiasis].

Aim: To identify the most likely metabolic disturbances and risk factors for stone formation in a group of patients with calcium oxalate urolithiasis, and to establish the relationship between the mineralogical composition of calculi and impaired excretion of inhibitors and promoters of stone formation.

Materials And Methods: Fifty patients with calcium oxalate urolithiasis were tested using a complex of physicochemical methods. Patients assessment included evaluation of quantitative mineralogical composition of calculi, daily urine pH profile and daily urinary excretion of urates, calcium, magnesium, oxalate, phosphate and citrate ions.

[Quantitative mineralogical analyzes of kidney stones and diagnosing metabolic disorders in female patients with calcium oxalate urolithiasis].

Objective: To conduct a complex examination of female patients with calcium oxalate urolithiasis to detect metabolic disorders, leading to stone formation.

Materials And Methods: The study was carried out using complex physical and chemical methods, including quantitative X-ray phase analysis of urinary stones, pH measurement, volumetry, urine and blood spectrophotometry.

Results: Quantitative mineralogical composition of stones, daily urine pH profile, daily urinary excretion of ions of calcium, magnesium, oxalate, phosphate, citrate and uric acid were determined in 20 female patients with calcium oxalate stones.

[Quantitative mineralogical analysis and structure of urinary stones in patients living in Ivanovo region].

This paper focuses on developing and implementing a method of quantitative mineralogical analysis of urinary stones based on powder diffraction data analysis using 4 Topas (Bruker) software. Mineralogical composition of 100 urinary stones from urolithiasis patients living in Ivanovo region was examined. More than 70% of stones consisted of calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD), and their mixtures with hydroxylapatite.

[DIAGNOSIS OF METABOLIC DISORDERS AND METAPHYLAXIS OF RECURRENT CALCIUM OXALATE UROLITHIASIS].

The paper presents the results of the 1-year screening of biochemical parameters of urine in female patient with recurrent calcium urate urolithiasis. Based on the data of quantitative X-ray phase analysis of the composition of stone and a complex of clinical and laboratory examination, reasons for recurrent stone formation were determined. The main reasons included hypocitraturia, hyperosmolarity of urine and uric acid diathesis.
