经会阴彩超联合磁共振精准前列腺穿刺对前列腺癌诊断的临床研究

Clinical study of precise prostate puncture by perineal color ultrasound combined with magnetic resonance in the diagnosis of prostate cancer

目的探究经会阴彩超联合磁共振(magnetic resonance imaging,MRI)精准前列腺穿刺对前列腺癌诊断的临床效果。方法回顾性分析2020年7月至2022年9月于笔者医院行前列腺穿刺患者80例作为研究对象,依据穿刺方法不同分为经直肠前列腺穿刺(transrectal prostate biopsy,TRPB)组(40例)及经会阴前列腺穿刺(transperineal prostate biopsy,TPPB)组(40例)。以病理检查结果为“金标准”,分析两种方法穿刺时间、穿刺针数、穿刺阳性针数、病理检查结果、Gleason评分及并发症发生率,并分析TRPB与TPPB在前列腺癌中的诊断价值。结果两组穿刺针数、穿刺阳性针数、病理检查恶性率、Gleason评分比较,差异无统计学意义(P>0.05);TRPB组穿刺时间长于TPPB组,差异有统计学意义(P<0.05)。TRPB组术后发热、穿刺点出血发生率均高于TPPB组,疼痛发生率低于TPPB组,差异有统计学意义(P<0.05);两组血尿、下尿路症状发生率比较,差异无统计学意义(P>0.05)。TPPB法诊断前列腺癌准确度为92.5%高于TRPB法的75.0%,差异有统计学意义(P<0.05)。两种方法诊断前列腺癌敏感度与特异性比较,差异无统计学意义(P>0.05)。结论应用经会阴彩超联合MRI精准前列腺穿刺在前列腺癌诊断中应用价值较高,能够有效降低发热及穿刺点出血等并发症发生风险,缩短手术时间,安全性较高,值得推广应用。

Objective To explore the clinical effect of perineal color ultrasound combined with magnetic resonance imaging(MRI)in the diagnosis of prostate cancer.Methods A retrospective analysis was performed on 80 patients with prostate biopsy in our hospital from July 2020 to September 2022.According to different puncture methods,they were divided into transrectal prostate biopsy(TRPB)group(40 cases)and transperineal prostate biopsy(TPPB)group(40 cases).With pathological examination results as the gold standard,puncture time,puncture needle number,puncture positive needle number,pathological examination results,Gleason score and complication rate of the two methods were analyzed,and the diagnostic value of TRPB and TPPB in prostate cancer was also analyzed.Results There were no significant differences in the number of puncture needles,the number of puncture positive needles,the malignant rate of pathological examination and Gleason score between the two groups(P>0.05).The puncture time in TRPB group was longer than that in TPPB group(P<0.05).The incidence of postoperative fever and puncture point bleeding in TRPB group was higher than that in TPPB group,and the incidence of pain was lower than that in TPPB group,with statistical differences(P<0.05).There was no significant difference in the incidence of hematuria and lower urinary tract symptoms between the two groups(P>0.05).The accuracy of TPPB method in the diagnosis of prostate cancer was 92.5%higher than that of TRPB method(75.0%),with statistical difference(P<0.05).There was no significant difference in sensitivity and specificity between the two methods for diagnosis of prostate cancer(P>0.05).Conclusion The application of perineal color ultrasound combined with MRI precision prostate puncture has high application value in the diagnosis of prostate cancer,which can effectively reduce the risk of complications such as fever and puncture point bleeding,shorten the operation time,and have high safety,which is worthy of promotion and application.
