摘　　要：目的:研究经直肠彩超检查对前列腺癌(PCa)和前列腺增生(BPH)的鉴别诊断价值。方法:选取兴义市人民医院在2022年12月-2023年11月间收诊的前列腺疾病患者90例(30例前列腺癌、60例前列腺增生)为实验组,另选取同期健康体检中心体检的50例健康志愿者为对照组,全部对象均接受经直肠彩超检查,收集整理不同对象的检查结果。结果:经直肠彩超检查对前列腺增生的诊断准确率为88.33%,对前列腺癌的诊断准确率为93.33%。与对照组健康志愿者相比,BPH和PCa患者的前列腺体积、上下径、前后径、左右径长度均有明显增加(P<0.05),而BPH与PCa患者的前列腺体积、上下径比较差异均无统计学意义(P>0.05);BPH患者的前后径、左右径长度均长于PCa患者(P<0.05);PCa患者与BPH患者的声像图特征(病灶部位、病灶回声、病灶形态是否规则、包膜是否完整、外腺是否对称)比较差异有统计学意义(P<0.05);与对照组内腺、外腺的阻力指数(RI)、舒张末期血流速度(Vd)、收缩期峰值血流速度(Vs)相比,PCa患者和BPH患者内腺、外腺的RI、Vd、Vs均有明显提高(P<0.05),其中BPH患者内腺与外腺的RI、Vd比较差异无统计学意义(P>0.05),但内腺的Vs高于外腺(P<0.05),PCa患者的RI、Vs均高于BPH患者内腺、外腺RI、Vs,而Vd则低于BPH患者的内腺、外腺Vd(P<0.05)。结论:经直肠彩超检查有助于早期鉴别诊断前列腺癌与前列腺增生,可结合声像图特征、血流特征鉴别诊断,值得推广。Objective:To study the differential diagnostic value of transrectal color ultrasound examination in prostate cancer(PCa)and benign prostatic hyperplasia(BPH).Methods:A total of 90 patients with prostate diseases(30 with PCa and 60 with BPH)admitted to Xingyi People's Hospital from December 2022 to November 2023 were selected as the experimental group,and 50 healthy volunteers from the same period were recruited as the control group.All participants underwent transrectal color ultrasound examination,and the results were collected and analyzed.Results:The diagnostic accuracy of transrectal color ultrasound examination for BPH was 88.33%,and for PCa was 93.33%.Significant increases were observed in prostate volume,upper and lower diameter,anterior and posterior diameter,as well as left and right diameter in both BPH and PCa patients compared to the control group(P<0.05).However,there were no significant differences in prostate volume and upper and lower diameter between BPH and PCa patients(P>0.05).The anterior-posterior and left-right diameters of BPH were longer than those of PCa(P<0.05).Significant differences in sonographic characteristics including lesion site,echo,morphological regularity,capsular integrity,and symmetry of the outer gland were observed between PCa and BPH patients(P<0.05).Compared with the control group,both PCa and BPH patients showed significant increases in resistive index(RI),vessel diameter(Vd),and blood flow velocity(Vs)of the inner and outer glands(P<0.05).However,no significant differences were observed in RI and Vd between the inner and outer glands in BPH patients(P>0.05),while the Vs of the inner glands was significantly higher than that of the outer glands(P<0.05).Additionally,PCa patients exhibited higher RI and Vs values than BPH patients for both inner and outer glands,but lower Vd values(P<0.05).Conclusion:The transrectal color ultrasound examination,when combined with sonogram and blood flow characteristics,proves beneficial for the early differential diagnosis of prostate can
