Abstract:

目的:探讨前列腺体积(PV)及膀胱出口梗阻(BOO)与前列腺穿刺活检阳性率的关系,从而探讨它们对于早期诊断前列腺癌的价值。方法:选择我院初次行前列腺穿刺活检的男性患者293例为研究对象,在术前进行经直肠超声检查、残余尿、尿流率及血前列腺特异性抗原(PSA)检查,以最大尿流率(Qmax)<10ml/s认为存在膀胱出口梗阻。结果:通过病检结果确认前列腺癌患者90例,非前列腺癌患者203例。根据PV及Qmax分别将患者分组,当PSA为4-10ng/ml时,若合并前列腺增生则穿刺阳性率下降至7.14%;合并BOO则下降至8.45%。结论:前列腺体积及膀胱出口梗阻是前列腺癌的可预测因素,其独立或联合均对指导临床上前列腺穿刺活检具有较高价值,在前列腺癌诊断中具有无创、方便、低风险性等优点
