经直肠超声造影在前列腺穿刺活检中的应用价值

The application value of transrectal contrast-enhanced ultrasound in prostate needle biopsy

目的:探讨经直肠超声造影在前列腺穿刺活检中的应用价值。方法:选取前列腺穿刺的90例患者,将所有患者根据不同的穿刺方法分为对照组50例和研究组40例,对照组采用常规的穿刺方法,研究组在穿刺中采用经直肠超声造影,对比两组患者穿刺病理结果及阳性率。结果:前列腺癌患者共37例,造影剂信号分布紊乱,癌变区域呈快速增强或消退,癌性结节呈快进快出的高增强;前列腺增生患者共53例,造影剂信号显示内腺增强早于外腺,且最先达到峰值强度,造影剂消退晚于外腺,造影剂信号分布均匀。研究组患者病理阳性率显著高于对照组(p<0.05)。结论:经直肠超声造影能准确的判定前列腺病变的良恶性及范围,可提高穿刺的准确率,具有重要的临床应用价值。

Objective:To evaluate the value of transrectal contrast-enhanced ultrasound in prostate needle biopsy.Methods:90patients undergoing prostate biopsy were divided into a control group of 50 cases and a study group of 40 cases,the control group used routine puncture method and the study group used transrectal ultrasound imaging during puncture,biopsy results and the positive rate of two groups were compared.Result:There were a total of 37 cases of prostate cancer patients,the contrast agent signal was disordered distribution,canceration area was rapidly increased or faded,cancerous nodules were highly reinforced;a total of 53 cases of patients had benign prostatic hyperplasia,the contrast agent signal displayed inner gland enhanced earlier than the outer gland,and reached the peak intensity first,the contrast agent subsided later than the outer gland,the contrast agent signal distributed evenly.The pathological positive rate of study group was significantly higher(P<0.05).Conclusion:Transrectal contrast-enhanced ultrasound can determine the range of benign and malignant prostate lesions,can improve the accuracy of puncture,which has important clinical value.
