摘要
目的：探讨经直肠能量多普勒超声（PDU）在前列腺穿刺活检中的临床应用价值，提高前列腺癌的诊断率。方法：对临床高度怀疑前列腺癌的54例病人在穿刺前完成经直肠二维灰阶超声的常规检查、PDU检查，根据检查结果选择经直肠二维灰阶超声、PDU及两者联合使用靶向穿刺结合6点前列腺系统穿刺活检方案。对比分析直肠二维灰阶超声、PDU靶向穿刺活检诊断前列腺癌的敏感性、特异性、阳性预测值、阴性预测值。结果：经直肠PDU检查发现异常血流增多37例，其中前列腺癌23例（包括2例为灰阶超声无异常发现的位于外腺的前列腺癌），前列腺增生症11例，前列腺癌不能除外1例， 前列腺占位1例（未定），转移性前列腺癌1例（膀胱癌）。结论：经直肠PDU能提高前列腺癌检测的敏感性与定位适合穿刺点，经直肠PDU靶向穿刺活检病理Gleason评分更高。
Abstract
Objective: To evaluate the clinical value of transrectal power Doppler ultrasonography(PDU) and PDU-directed prostatic biopsy to improve the diagnosis of prostatic cancer. Methods: Fifty-four patients suspected to be prostatic cancer underwent routine gray-scale TRUS, transrectal PDU of the entire gland before biopsy. According to the result, select the protocols of gray-scale TRUS, transrectal PDU and combined use of six-score transrectal biopsy protocols. The sensitivity, specificity, positive predictive value, negative predictive value were compared and analyzed. Results: Abnormal flow was detected by power Doppler scanning in 37 patients, among them 23 cases were of prostatic cancer(two of them were normal on gray-scale image), BPH in 11 cases, prostatic cancer cannot be ruled out in 1 case, prostatic mass of undetermined nature in 1 case, metastatic prostatic cancer of bladder origin in 1 case. Conclusions: Transrectal PDU can improve the sensitivity of cancer detection, and can determine the correct site for PDU-directed biopsy, the Gleason score is significantly higher.
