目的分析超声引导下经直肠行前列腺穿刺活检术的临床应用价值。方法选取于2013年12月至2016年1月间于本院就诊的前列腺癌的病人120例,对病人行PSA(前列腺特异性抗原)检查和前列腺穿刺活检术并进行诊断,诊断结果与病理确诊结果进行比较,分析经直肠超声引导下前列腺穿刺活检术的确诊率以及术后并发症的发生情况。结果120例患者中,穿刺活检结果中诊断为前列腺癌的为68例(56.67%),良性增生26例(21.67%),慢性炎症及内皮瘤等其他疾病26例(21.66%),手术病理确诊为前列腺癌的为78例(65.00),良性增生19例(15.83),慢性炎症及内皮瘤等其他疾病23例(19.16)。前列腺癌漏诊率为12.82%。随着血清PSA水平的升高,前列腺癌穿刺活检的诊断准确率越高,4~10μg/L时准确率为20.00%,11~20μg/L时准确率为49.01%,>20μg/L时准确率为79.86%。术后患者出现肉眼血尿占19.17%,大便带血占6.67%,发热占4.17%,症状多在1周内自行恢复。结论超声引导下的前列腺穿刺活检术对于早期前列腺癌具有较高的诊断价值和安全性,若在此基础上联合PSA检查可以有效提高该方法的阳性率。
Objective To analyze the clinical value of transrectal prostate biopsy guided by ultrasound. Methods A total of 120 patients with prostate cancer were selected from December 2013 to January 2016 in our hospital. PSA (prostate specific antigen) and prostate biopsy were performed on the patients. The diagnosis and pathology were confirmed The results were compared and analyzed the diagnosis of transrectal ultrasound-guided prostate biopsy and the incidence of postoperative complications. Results Among the 120 patients, 68 (56.67%) were diagnosed as prostate cancer, 26 (21.67%) were benign hyperplasia, 26 (21.66%) were other diseases such as chronic inflammation and endothelioma, Prostate cancer was found in 78 cases (65.00), benign hyperplasia in 19 cases (15.83%), chronic inflammation and other diseases such as endothelioma in 23 cases (19.16). The rate of missed diagnosis of prostate cancer was 12.82%. With the increase of serum PSA level, the diagnostic accuracy of prostatic cancer biopsy was higher, the accuracy rate was 20.00% at 4 ~ 10μg / L, 49.01% at 11 ~ 20μg / L and accurate at> 20μg / L The rate was 79.86%. Postoperative patients with gross hematuria accounted for 19.17%, stool blood accounted for 6.67%, fever accounted for 4.17%, the symptoms more than 1 week in their own recovery. Conclusion Ultrasound-guided prostate biopsy has high diagnostic value and safety for early-stage prostate cancer. On this basis, combined with PSA test can effectively improve the positive rate of this method.
