摘　　要：目的:探讨前列腺增生相关性血尿的经直肠彩色多普勒超声特征。方法:对53例诊断为前列腺增生患者经直肠超声观察其前列腺动脉尿道支,测量其最大血流速度(V_(max))、最小血流速度(V_(min))、阻力指数(RI)。进行统计学处理。结果:良性前列腺增生相关性血尿组及非血尿组前列腺动脉V_(max)均值分别为(23.07±3.71)cm/s、(17.12±4.25)cm/s(P=0.00),V_(min)均值分别为(4.75±3.26)cm/s、(5.07±2.54)cm/s(P=0.35),RI均值分别为(0.79±0.035)、(0.67±0.041)(P=0.00)。结论:经直肠彩色多普勒超声可显示前列腺动脉尿道支,出现前列腺增生相关性血尿的患者,前列腺腺体血流信号增加,前列腺动脉最大血流速度增快,血供增加,血管阻力指数增大。V_(max)及RI可作为良性前列腺增生相关性血尿的预测指标。Objective：To study the characteristics of hematuria associated with benign prostatic hyperplasia examined with transrectal color doppler ultrasound. Methods：53 patients who were diagnosed as benign prostatic hyperplasia were observed prostatic urethral artery branch with transrectal ultrasound. The measured parameters of the velocity of maximum （Vmax） and minimum （Vmax）, resistance index （RI） were analyzed in statistics. Results： The parameter of the urethral artery of prostate： the mean of Vmax was respectively （23.07± 3.71）cm/s, （17.12 ±4.25）cm/s （P=0.00）, Vmin were respectively （4.75±3.26） cm/s, （5.07±2.54） cm/s（P=0.35） and RI was respectively （0.79±0. 035）, （0.67±0. 041）（P=0.00）（P〈 0.05）. Conclusions：Transrectal color Doppler ultrasound can show the prostatic urethral artery branch. The patients with prostatic hyperplasia--related hematuri a, blood flow signals of prostate glands increased, V speeded up, blood supply increased, the vascular resistance index increased. The velocity of maximum and RI examined could be used as the index for the prognostication of hematuria associated with benign prostatic hyperplasia.
