用HP Sonos1000与2500型彩超仪7.5MHz探头,从会阴部进行前列腺血管的血流动力学检查.25例健康人:前列腺会阴部横切面椭圆形,彩色血流显示于5点、7点处,有2支小动脉相当于来自膀胱下动脉的前列腺包膜支,内径(D)1.7±0.25 mm,最大速度(Vmax)22.2±8.2 cm/s,血流量(V)8.02士6.5ml/min.矢状斜切面,可见树枝状分支进入实质内的尿道支动脉分布在尿道周围,D1.8±0.2 mm,Vmax 25.6±10.2 cm/s,V 9.5±3.69 ml/min.矢状切面近膀胱尿道内口处蓝色血流为膀胱前列腺静脉丛,D为3.5±1.0mm,血流速度大小随呼吸变化.前列腺增生血流速度及血流量均少于正常前列腺.

The hemodynamic examination of prostate was performed transperineally by HP SONOS 1000 or 2500 Ultrasound System with 7.5 MHz transducer.The results of 25 healthy persons showed that:1.In transverse section,two arteries locatced at 5 and 7 o'clock corresponded to the capsule branches of prostate artery with diameter(D)1.7±0.25mm,Vnlax 22.2±8.2cm/s,flow volume(V) 8.O±6.5ml/min;2.The sagittal view showed the urethra branch of prostate artery,red in colonr,D 1.8±0.2mm,Vmax 25.6±10.2cm/s,V 9.5±3.69mI/min.3.Blue streams with lOW velocity were seen near the internal orifice of urethra,were vesicoprostatic venous plexus with D 3.5±1.0mm,their velocity varied with respiration.In presence of prostatic hypertrophy,the velocity and flow volume were less than those in normal case.
