摘  要:目的探讨血清PSA浓度为4~10ng/ml患者前列腺内腺体积与总体积之比在前列腺癌筛选中的应用价值。方法通过分析41例血清PSA浓度为4~10ng/ml患者在经直肠前列腺穿刺术或经尿道前列腺电切术前经直肠前列腺彩色多普勒超声所得内腺体积与腺体总体积的比例,对照术后病理结果进行分析。结果术后病理诊断为前列腺增生的患者术前经直肠前列腺B超前列腺内腺体积与总体积之比95%大于0.50,62%病理诊断为前列腺癌的患者该值小于0.50。结论经直肠前列腺穿刺活检结果阴性的患者,前列腺内腺体积与总体积之比<0.50可作为重复穿刺活检的指征之一。Objective To study the Applicable value of the ratio of inner gland volume to bulkvolume of prostate in screening prostatic carcinoma when patient's prostate specific antigen(PSA) concentration is 4-10ng /ml. Methods Using colour doppler ultrasounic examination through recta to obtain the ratios of inner gland volume to bulkvolume of prostate in 41 cases, of which the patients' serum PSA concentration arc between 4-10ng /ml, and the ratios have been analyzed by comparing pathologic consequence after biopsy or TURP. Results The ratio between inner gland volume and bulkvolume of prostate is more than 0.50 for 95% of patients who are pathologically diagnosed as prostatic hyperplasia after operation, and the ratio is less than 0.50 for 62% of patients who are pathologically diagnosed as prostatic carcinoma. Conclusion It can be one of the indications to do repeated biopsy for patients, of whom the consequence of prostate biopsy is negative, and the ratio between inner gland volume and bulkvolume is bss than 0.50.
