MRI联合TRUS检查对前列腺癌穿刺检出率的影响

The Influence of MRI Combined with TRUS Examination on the Detection Rate of Prostate Cancer Puncture

探讨核磁共振(MRI)联合经直肠超声(TRUS)检查对前列腺癌穿刺检出率的影响。回顾性分析150例疑似前列腺癌患者的临床资料,根据穿刺指导方式将其分为A组、B组、C组,A组于TRUS引导下穿刺,B组于MRI引导下穿刺,C组于MRI联合TRUS引导下穿刺。经Kappa检验分析各检查方式与手术病理诊断的一致性,记录三组并发症发生率。结果显示,A组、B组、C组结果与病理诊断的一致性分别为0.505、0.585、0.664;三组血便、尿潴留、血尿、低热发生率比较无显著差异(P>0.05)。与单纯MRI或TRUS引导下行前列腺穿刺相比,采用MRI联合TRUS引导下进行前列腺穿刺与手术病理诊断的一致性最高。

To investigate the effect of MRI combined with TRUS on the detection rate of prostate cancer.The clinical data of 150 patients with suspected prostate cancer were analyzed retrospectively.All patients were given puncture biopsy.According to the puncture guidance,they were divided into group A,group B and group C.Group A was punctured under the guidance of TRUS,group B under the guidance of MRI,and group C under the guidance of MRI combined with TRUS.Kappa test was used to analyze the consistency between the examination methods and the surgical pathological diagnosis.The complication rate of the three groups was recorded.The results showed that the consistency of group A,group B and group C with pathological diagnosis was 0.505,0.585 and 0.664,respectively.There was no significant difference in the incidence of bloody stool,urine retention,hematuria and low fever between the three groups(P>0.05).Compared with MRI alone or TRUS guided prostate puncture,MRI combined with TRUS guided prostate puncture had the highest consistency with surgical pathological diagnosis.
