目的对照分析单纯经腹彩超诊断前列腺癌与彩超联合PSA诊断符合率。方法经腹彩超联合PSA组为A+B组,单独彩超组为B组,单独PSA组为C组,对照分析三组患者的诊断符合率及漏诊率。结果联合检查组、单纯彩超及单纯PSA的诊断符合率分别为77%、52%、67%;误诊率分别为23%、48%、33%。两组患者间存在统计学差异(P<0.05)。结论经腹彩超联合PSA检查有效提高前列腺癌的诊断符合率,减少单纯经腹彩超诊断过程中漏诊和误诊率。
Objective To comparatively diagnose the coincidence rate of prostate cancer and color Doppler ultrasound in the diagnosis of prostate cancer by abdominal ultrasonography alone. Methods The transabdominal ultrasonography combined with PSA was performed in group A + B, group B was treated by ultrasound alone, group C was treated by PSA alone, and the diagnostic coincidence rate and missed diagnosis rate were compared between the three groups. Results The coincidence rates of the combined examination, simple ultrasound and simple PSA were 77%, 52% and 67%, respectively. The misdiagnosis rates were 23%, 48% and 33% respectively. There was a statistically significant difference between the two groups (P <0.05). Conclusion Transabdominal ultrasonography combined with PSA can effectively improve the coincidence rate of diagnosis of prostate cancer and reduce the misdiagnosis and missed diagnosis of transbronchial ultrasonography.
