High prevalence of pediatric urinary tract stones in Xinjiang Uyghur

The aim of the study was to report the characteristics of urolithiasis in Uyghur patients from Xinjiang, China. The composition of stones collected from 1863 patients in the Uyghur region of Xinjiang was analyzed. The median age of patients was 17 years [25th and 75th percentiles: 2, 36]. The stones were delivered by 1299 males (69.7%) and 564 females (30.3%). Calcium oxalate was the predominant stone component in 42.1% of the patients, followed by ammonium urate in 20.6%. Females had formed more stones of magnesium ammonium phosphate 8.9 vs. 5.6% ( p = 0.010) and carbonate apatite 6.2 vs. 3.3% ( p = 0.004). In contrast uric acid was more common in males than in females; 21.6 vs. 15.1% ( p = 0.001). In this series, pediatric patients (age range 0–18) were more likely to present with a stone (51.5%, p
