目的探讨经直肠超声(TRUS)引导下重复穿刺活检在前列腺特异性抗原(PSA)升高或直肠指检阳性的前列腺癌(PCa)可疑人群中的诊断价值。方法在首次穿刺活检诊断为前列腺良性病变的45例Pca高危人群中开展TRUS引导下10点重复穿刺活检。平均年龄78(58～92)岁;45例患者PSA均大于2.6 ng/ml,其中12例直肠指检异常。结果在45例前列腺重复穿刺的患者中,34例穿刺2次,8例穿刺3次,3例穿刺4次;确诊Pca 10例(22.2%),良性前列腺增生32例,慢性前列腺炎3例。结论在Pca高危人群中开展TRUS引导下重复穿刺可以提高Pca的诊断率。
Objective To investigate the diagnostic value of repeat biopsy guided by transrectal ultrasound (TRUS) in the suspicious population of prostate cancer (PCa) with elevated prostate-specific antigen (PSA) or positive digital rectal examination. Methods Ten repeat puncture biopsies were performed under the guidance of TRUS in 45 high risk Pca patients diagnosed as benign prostatic diseases by first biopsy. The average age was 78 (58-92) years old. All 45 patients had a PSA> 2.6 ng / ml, of which 12 had abnormal digital rectal examination. Results Among the 45 cases of prostatic repeated puncture, 34 cases were punctured twice, 8 cases punctured three times and three cases punctured four times. 10 cases (22.2%) were diagnosed with Pca, 32 cases had benign prostatic hyperplasia and 3 cases had chronic prostatitis. Conclusion Repeated puncture guided by TRUS can increase the diagnosis rate of Pca in high risk population of Pca.
