Stone composition analysis of 762 children with urinary tract stones in Xinjiang

Abstract

Objective To find the differences of urinary stone composition of children in Xinjiang among different ethnics, genders and age groups and provide evidence for the treatment of those suffered children. Methods Stone IR automatic analyzer was used to analyze stone composition of upper urinary tract calculi specimens from 762 children who were hospitalized between January 2009 and March 2013, and clinical data were compared. Results The analysis of stone composition of 762 children with urinary calculi showed that: (1)Calcium stones accounted for 79.0%, far more than other types and no significant difference between genders (P> 0.05). (2) Children aged 0 to 5 years accounted for 48.7%. Gender distribution of age groups were significantly different, with female children in 11 to 15 years group accounting for 31.8%, far more than males, and males accounting for more in the other age groups (P 0.05). (4) Distribution of children with uric acid stones was significantly different (P 0.05). Conclusions Calcium stones account the highest in urinary stones in children in Xinjiang, followed by uric acid stones, and urinary calculi is more common in Uygur male children than female children. Surgical intervention and drug dissolving should be balanced for the treatment. Key words: Urinary calculi; Stone composition; Infrared rays
