摘要
目的 :探讨经直肠彩色多普勒超声对小前列腺增生的诊断价值。方法 :应用经直肠彩色多普勒超声对 3 0例正常组和 3 6例小前列腺增生患者组进行对比观察。结果 :小前列腺增生时前列腺体积变化无特异性 ,主要表现为移行区指数 (TZI)增大或伴增生结节形成 ;而内腺动脉收缩期血流峰值 (Vs)和阻力指数 (RI)均有明显差异 (P <0 .0 5 )。结论 :小前列腺增生时 ,前列腺移行区指数增大 ,内腺血液供应增多 ,内腺动脉收缩期血流峰值和血流阻力增大。经直肠彩色多普勒超声对小前列腺增生具有诊断价值。
Objective:To evaluate the color Doppler flow image for diagnosis of small prostatic hyperplasia.Methods: thirty normal subjects and thirty-six patients with small prostatic hyperplasia were studied with transrectal color Doppler flow image.Results:There was no remarkable change in the prostatic volume,but there was enlargement of the transition zone index (TZI) or formation of hyperplastic nodule.The systolic velocity (Vs) and resistance index (RI) of the artery in the hyperplastic prostata differed from that of the normal subjects (P<0.05).Conclusion:In small prostatic hyperlasia the transition zone index is enlarged.The artery in the gland is in a state of high flow, the systolic velocity is increased and resistance index is enlarged.Transrectal color Doppler flow image is valuable in the diagnosis of small prostatic hyperplasia.
