Table 2.

Comparison of adipose tissue FA composition between patients with uric acid kidney stones and MS and the patients with calcium-based kidney stones without MS.

FA (provided by percentage of total amount)	Uric acid (n=11)	Calcium oxalate/phosphate (n=38)	P value
	With MS	Without MS
	Mean ± Standard deviation
Total PUFA	12.61±1.70	14.64±2.88	p=0.037
∑* ω**6	11.94±1.6	13.97±2.71	p=0.042
C 18: 2ω6***	11.62±1.57	13.55±2.61	p=0.042

PUFA – polyunsaturated fatty acids; ∑* – total sum; ω** – position of double bond between carbon atoms; C 18: 2ω6*** – number of carbon atoms and double bonds. Mean and standard deviation of other fatty acids (C 14: 0, C 16: 0, C 18: 0, C 16: 1ω7, C 18: 1ω9, C 18: 1ω7, C 20: 1ω9) were not statistically significant.
