前列腺增生并发膀胱结石的高危因素分析

Analysis of the high risk factors of bladder calculi combined with benign prostatic hyperplasia

目的:分析探讨前列腺增生症(BPH)患者并发膀胱结石的高危因素。方法:回顾性分析2011年1月~2014年9月收治308例BPH患者的临床资料,将其中合并膀胱结石的68例患者纳为第1组,无膀胱结石的240例患者纳入第2组。分析膀胱结石成分,并对患者的年龄、国际前列腺症状评分(IPSS)、膀胱内前列腺突入程度(IPP)、剩余尿量、前列腺总体积(TPV)、前列腺移行区体积(TZV)、膀胱出口梗阻指数(BOOI)、尿动力学参数进行高危因素分析。结果:308例患者中,合并膀胱结石的BPH患者的总发生率为22.08%,结石成分含草酸钙的44例(64.7%),含尿酸结石31例(45.6%);两组患者间的年龄(P=0.005),TPV(P=0.003),TZV(P<0.004),IPP(P<0.001),Qmax(P=0.011),差异有统计学意义。结论:年龄、TPV、TZV、IPP是BPH并发膀胱结石形成的高危因素。

Objective:To study the high risk factors that influence bladder calculi formation in patients with benign prostatic hyperplasia.Methods:We retrospectively reviewed the clinical data of 308 patients with benign prostatic hyperplasia combined with bladder calculi in our hospital during Jan.2011 to Sep.2014.Results:The overall incidence of bladder stone in 308 patients with BPH was 22.07%.There were 44 cases of calcium oxalatecontaining stone(64.7%),and 31 cases of uric acid-containing stone(45.5%).The patients' age,TPV,TZV,IPP and the Qmax were significantly different between two groups.Conclusions:This study demonstrated that age,TPV,TZV,IPP and Qmaxare high risk factors of the occurrence of bladder calculi in patients with benign prostatic hyperplasia.
