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 investigate the value of transrectal ultrasonography in prostate biopsy. Methods: Ninety patients with prostatic puncture were selected. All patients were divided into control group (n = 50) and study group (n = 40) according to different puncture methods. Conventional puncture method was used in control group. Transrectal contrast echography Two groups of patients with pathological results and positive rate of puncture. Results: A total of 37 cases of prostate cancer patients, the distribution of contrast agent signal disorder, rapid increase or regression of cancerous areas, cancerous nodules were fast forward fast out of high enhancement; benign prostatic hyperplasia patients a total of 53 cases, contrast agent signals show that the gland is enhanced Early than the outer gland, and the first to reach the peak intensity, contrast agent faded later than the outer gland, contrast agent signal distribution. The pathological positive rate of the study group was significantly higher than that of the control group (P <0.05). Conclusion: Transrectal ultrasonography can accurately determine the benign and malignant prostatic lesions and range, can improve the accuracy of puncture, has important clinical value.
