经直肠超声在前列腺疾病诊断中的应用价值分析

Application value of transrectal ultrasound in diagnosis of prostate diseases

目的研究经直肠超声在前列腺疾病诊断中的应用价值。方法选取2010年1月~2015年1月入院诊治的疑似前列腺疾病患者225例,分别应用经腹及经直肠超声检查前列腺,以直肠穿刺病理活检为诊断＂金标准＂,对比两种检查方法的诊断符合率、灵敏度和特异度。结果病理诊断前列腺正常43例,前列腺癌20例,前列腺增生122例,前列腺炎13例,前列腺囊肿27例。以病理诊断结果为＂金标准＂,经直肠超声诊断的灵敏度为89.01%、特异度为74.42%、符合率为86.22%,均显著高于经腹超声（分别为73.62%、60.47%、71.11%）（P〈0.05）。结论经直肠超声检查前列腺疾病具有更高的分辨率,可有效观察细小病变,显著提高前列腺疾病的正确诊断率,显著优于经腹超声。

Objective To investigate the application value of transrectal ultrasound in the diagnosis of prostate diseases.Methods 225 cases suspected of prostate diseases visited the hospital between January 2010 and January 2015 were chosen and received abdominal and transrectal ultrasound inspections, recepectively. The golden criterium of the diagnosis was rectal pathological biopsy. The diagnose accordance rate, the sensitivity, and the specificity of the two inspection methods were compared. Results Pathologic diagnosis showed there were 43 cases of normal prostate, 20 ones of prostate cancer, 129 ones of prostatic hyperplasia, 13 ones of prostatitis, and 27 ones of prostate cyst. According to the pathological diagnostic results, the sensibility of transrectal ultrasound diagnosis was 89.01%; the specificity was 74.42%; the accordance rate was 86.22%, which were all higher than those of transabdominal ultrasound（73.62%, 60.47%, and 71.11%, respectively）（P〈0.05）. Conclusion Transrectal ultrasound has a higher resolution in the examination of prostate diseases. It can effectively observe small lesions and improve the accuracy of diagnosis for prostate diseases, which is superior to transabdominal ultrasound.
