Age And Gender Distribution And Composition Analysis Of Urinary Stones As Well As Its Prevention And Treatment In Chang Chun Area

Objective:To determinate the urinary stones composition that acquired in urological surgeryof China-Japan Union Hospital using infrared spectroscopy. To explore the relationsbetween the composition of urinary stones and patients’ age、gender， compare theupper and lower urinary tract stones component characteristics, analyze theepidemiological situation of urinary stones in Chang Chun area, provide effectiveindividualized treatments and preventive measures for clinic.Methods:Collect451cases of urinary stones that treated in the Urology of China-JapanUnion Hospital from2012.1-2014.2, and analyze the collected urinary stonesusing infrared spectroscopy quantitative analysis with the agreement of patients.Obtain the composition ratio of each component. Limit conditions for the residenceof Chang Chun area and screen results obtained from the analysis.239urinary stonespatients living in Changchun area were enrolled. Their clinical data of age, gender,as well as the position and composition of stones were collected and sorted. Analyzethe age and gender distribution of urinary stones in Chang Chun region, and comparethe characteristics of the composition of urinary stones between upper urinary tractand lower urinary tract at the same time. Application of SPSS19.0software, usingchi-square test and Fisher’s exact test for statistical analysis of the results, P <0.05indicates significant difference.Results:The average age of239urinary stones patients who live in Chang Chun regionwere49.6, and46to55years old was the peak age group of urinary stones incidencein Chang Chun area (37.24%), besides this age group was pathogenic climax both inmen and women. More men than women had urinary stones, and the sexual ratio was1.75:1. In66~75years of age, incidence of urinary stones had gender differences（P=0.046）. Stone composition was major in mixed stones, which had191cases,accounting for79．92％. There were237cases of upper or lower urinary tract stones, and most of their chemical composition contained calcium oxalate, accounting for89.54%and93.72％was upper urinary tract, therefore primary down urinary tractstones was rare. The cases of predominant calcium oxalate stones were173,accounting for72.38%. The cases of predominant uric acid stones were15,accounting for6.28%.The cases of predominant infectious component stones were37,accounting for15.48%. The cases of predominant calcium oxalate stones were173,accounting for72.38%.Young patients (age≤45years of age) were mostly withpredominant calcium oxalate stones, and infection stones. Elderly patients (age≥46years of age) were mostly with predominant calcium oxalate stones, infection stones,and uric acid stones; The gender differences of patients with infective calculus ofurinary stones were statistically significant（P=0.04）.Conclusion:1．Urinary stones component was complex in Chang Chun area，and most of themcontained calcium oxalate component. Calcium oxalate+carbonated apatite were themost common combination of mixing components stones.2.46to55years old wasthe peak age group of urinary stones incidence in Chang Chun area.3. The sexualratio was1.75:1; From66to75-year-old age gender differences of urinary stonesincidence were statistically significant; the rest of all ages were not statisticallysignificant between men and women urinary stones incidence ratio.4. Uric acidstones and infection stones had a higher incidence in high age grope than in low agegrope.5. In infectious composition mainly type stones, incidence of female washigher than male, and the difference was statistically significant.
