Component analysis of 251 cases of urinary calculi in Uigurs and Han in Xingjiang

To explore the relationship between urolithiasis and related factors by chemical analysis of urolithic components in the urine and serum of Uigurs and Han in Xingjiang.

A series of 251 inpatients' urinary calculi (Uigurs: 148; Han: 103) were qualitatively chemically analyzed. Their serum and urine biochemistry was determined using an automatic biochemical machine.

There are significant differences between the Uigurs and the Han (p<0.05) in the ratio of reoccurrence of urinary calculi, age and region; calcium oxalate has the highest concentration (Uigurs: 75.68%; Han: 60.78%). There are significant differences (p<0.05) in serum phosphate (HPO42-) levels, urine specific gravity and uric acid, with the Uigurs having higher levels than that of the Han.

1. Differences in distributions of urolithic components between Uigurs and Han in Xingjiang are not significant; 2. The ratios of reoccurrence and ages are significantly different. The children and youth of Uigurs have higher rates of occurrence than the Han. There are notable differences in serum HPO42-, urine specific gravity, and uric acid between Uigurs and the Han. The ratio of Uigurs is notably higher than that of the Han. All these differences may result from differences in race, dietary habits, and physical activity.
