Analysis of clinical characteristics of urinary calculi in children

Abstract

Objective To analyze the sex and age distribution, the location of stone and the composition of stones of urinary calculi in children. Methods Ninety children with urinary urinary stones were treated by operation in hospital were selected as study subjects. According to the characteristics of s growth and development of children, they were divided into infant group (0-3 years old) of 55 cases, preschool group (4-6 years old) of 23 cases, and school age group (7-12 years old) of 12 cases.The sex and age distribution, the location of stone and the composition of stones of urinary calculi in children were analyzed by infrared spectroscopy and chemical method. Results Among the children with urinary calculi, the number of males was more than that of women (7: 2), and the younger the children was, the more obvious the trend was; the incidence of upper urinary calculi in the three groups was higher than the incidence of lower urinary calculi, and the difference was significant (χ2=33.136, P<0.01). There were 45 cases of right urinary calculi, which was significantly higher than that of the left urinary tract stone (25 cases), and the difference was significant (χ2=4.519, P<0.05). Calcium oxalate was found in 56 cases of urinary calculi, 29 cases of calcium phosphate and 12 cases of infection, 8 cases of cystine contains, other components of 2 cases. Calcium oxalate was the most common ingredient in the stone, followed by calcium phosphate and uric acid. In all urinary calculi, there were 40 cases of single component stones. Among the all urinary calculi, there were 40 cases of single component stones, of which 24 cases were simple calcium oxalate stones and 50 cases were mixed into classified calculi. Conclusions Urinary calculi in children mainly occur in male children, the main part of the disease is upper urinary calculi, and calcium oxalate is the main component of the stone. Key words: Urinary calculi in children; Stone site; Calculus composition; Calcium oxalate
