306例膀胱结石成分及相关危险因素分析

目的探讨膀胱结石患者发病年龄、性别及结石成分的特点,为临床防治提供依据。方法采用傅立叶红外光谱压片法分析306例膀胱结石成分,按年龄每10岁一组划分,性别及化学成分列表作相关分析。结果 306例膀胱结石中224例是含钙结石（73.20%）,以草酸钙为主,其中单纯草酸钙72例（23.53%）;含磷酸盐161例（52.61%）;含尿酸盐115例（37.58%）,其中纯尿酸55例（17.98%）;单一成分结石127例（41.50%）,2种成分混合性结石107例（34.97%）,3种成分混合性结石72例（23.53%）,混合结石共179例（58.50%）。男性膀胱结石患者284例,占92.81%,50岁以上发病率占87.32%。结论膀胱结石成分以含钙结石、磷酸盐和尿酸盐为主,男性、高龄是膀胱结石患病的危险因素。

Analysis of composition and risk factors of bladder calculi from 306 cases

Objective To study the age and gender of patients with bladder calculi and the composition of calculi in order to provide evidence for the prevention of bladder calculi.Methods The composition of 306 cases of bladder calculi was analyzed with Fourier transform infrared spectroscopy.The patients were grouped according to age and gender.Results 224 of the 306 cases were calcium stones（73.20%）,of which 72 were calcium oxalate（23.53%）.161 cases were phosphate（52.61%）.115 cases were urate（37.58%）,of which 55 were pure urate（17.98%）.Of all the cases,127 were single-component calculi（41.50%）,107 were two-component calculi（34.97%） and 72 were three-component calculi（23.53%）.284 patients were male（92.81%） and 87.32% of them were older than 50 years of age.Conclusion Calcium,phosphate and urate were the major components of bladder calculi.Male with old age were prone to suffer from bladder calculi.
