Infrared Spectroscopic Analysis And Clinical Investigation Of868Urinary Calculi Patients

Objective:To preliminary find Jiangxi urolithiasis Clinical distribution characteristics,byretrospective analysis of gender, age, calculus location, calculus component and otherclinical features of868patients with urolithiasis in Jiangxi region,in order to providea preliminary theoretical basis for prevention and treatment of urinary calculi inJiangxi.Methods:1. Collect gender, age, calculus location and other clinical features of868patients treated from February2011to December2012in our hospital, analyse theclinical distribution characteristics of Jiangxi urinary calculi.2.Collect calculus specimens of these patients, analyse the calculus componentof these calculus specimens by infrared spectroscopy automatic analyzer,preliminarily investigate the characteristics of calculus component of the Jiangxiurinary calculi combined with clinical data.Results:According to calculus component,868urinary calculi patients divided into thefollowing2groups: single component calculus group (326,37.56%) and mixedcomponent calculus group (542,62.44%). In the single component calculus group,252patients calculus composition was calcium oxalate calculus, accounting for29.03%, and49patients uric acid calculus, accounting for5.65%,9patientscarbonate apatite, accounting for1.04%,3patients cystine calculus, accounting for0.35%; mixed component calculus group mainly included calcium oxalate mixedcarbonate apatite, a total of359cases, accounting for41.36%. The proportion of maleand female patients was1.27:1(486/382), the peak age of onset is30-59years old.799patients were upper urinary tract calculi, accounting for92.1%, and69patients(7.9%) lower urinary tract calculi.Conclusion:1. Presence of calculi is more common in men than in women, with particular incidence in those between30to59years old.2. The proportion of upper urinary tract calculi in the region was significantlyhigher than the lower urinary tract calculi.3. In the region, the most common single component calculus was calciumoxalate, while the most frequent mixed component calculus was calcium oxalate andcalcium phosphate mixture.
