Abstract: 目的:探讨经直肠超声(TRUS)测量的前列腺移行区与国际前列腺症状评分(IPSS)、最大尿流率(Qmax)及残余尿量(PVR)之间的关系,以及移行区指数(TZI)在评估良性前列腺增生(BPH)中的价值.方法:286例BPH患者进行IPSS评分、Qmax及PVR测量,TRUS测量前列腺体积(TPV)及移行区体积(TZV),计算移行区指数(TZI=TZV/TPV).结果:TPV与IPSS(r=0.092,P>0.05)、Qmax(r=-0.125,P>0.05)、PVR(r=0.078,P>0.05)之间均元显著相关性;TZV与IPSS(r=0.385,P<0.01)、Qmax(r=-0.412,P<0.001)、PVR(r=0.426,P<0.001)之间有显著相关性.TZI与IPSS(r=0.436,P<0.001)、Qmax(r=-0.534,P<0.001)、PVR(r=0.528,P<0.001)之间有显著相关性.TZI>0.50的患者与TZI<0.50的患者相比,IPSS、Qmax及PVR差异有显著性(P<0.01).结论:移行区指数与BPH的症状相关,且可有效评估梗阻的严重程度.
