目的：评价经直肠超声引导下前列腺多点穿刺活检技术的临床应用价值。方法：对９７例临床高度怀疑前列腺癌的患者进行经直肠超声引导下前列腺多点穿刺活检。结果：经病理证实前列腺癌３４例，前列腺增生症４１例，前列腺内皮瘤形成９例，鳞状上皮化生１例，不典型增生２例，炎症９例，结核１例。在前列腺癌中，癌肿≤１．０ｃｍ的患者占１７．６％，还有２０．６％的患者声像图检查时未显示前列腺占位性病变。结论：经直肠超声引导下前列腺穿刺活检的准备简单，患者痛苦小，操作时间短，准确性好，安全。运用该技术穿刺前列腺有助于前列腺疾病的鉴别诊断和提高前列腺癌的早期诊断率，并为前列腺癌提供分期依据
Objective: To evaluate the clinical value of transrectal ultrasound-guided prostate biopsy. Methods: Ninety-seven patients with highly suspected prostate cancer underwent transrectal ultrasound-guided prostate biopsy. Results: There were 34 cases of prostate cancer, 41 cases of benign prostatic hyperplasia, 9 cases of prostatic endothelioma, 1 case of squamous metaplasia, 2 cases of dysplasia, 9 cases of inflammation and 1 case of tuberculosis. In prostate cancer, 17.6% of patients with cancer ≤1.0cm, and 20.6% of patients did not show benign prostate lesions in sonographic examination. Conclusion: The preparation of prostate biopsy guided by transrectal ultrasound is simple, patient suffering is small, operation time is short, accuracy and safety are good. Prostate puncture using this technique contributes to the differential diagnosis of prostate diseases and to improve the early diagnosis of prostate cancer, and provide staging basis for prostate cancer
