目的: 探讨慢性前列腺炎、前列腺增生时前列腺内部的血流变化。方法: 应用经直肠彩色多普勒血流显像对20 例正常人、85 例慢性前列腺炎、87 例慢性前列腺增生患者的前列腺进行观察。结果: 慢性前列腺炎和前列腺增生时前列腺内腺动脉内径(D), 收缩期血流峰值(Vs), 阻力指数(RI) 均有相应的变化, 以前列腺增生时更明显, 并与前列腺内腺大小呈良好正相关(P< 0.05)。外腺动脉的各项参数则无明显差异(P> 0.05)。正常对照组, 慢性前列腺炎组, 前列腺增生组内腺动脉RI的平均值分别为0.52, 0.57, 0.68。结论: 慢性前列腺炎、前列腺增生时,前列腺内腺血液供应增多, 血流阻力增大
Objective: To investigate the changes of blood flow in the prostate during chronic prostatitis and prostatic hyperplasia. Methods: Transrectal color Doppler flow imaging was used to observe the prostate of 20 normal subjects, 85 chronic prostatitis and 87 chronic prostatic hyperplasia patients. Results: There was a corresponding change in the diameter (D), the peak of systolic blood flow (Vs) and the resistance index (RI) of chronic prostatitis and benign prostatic hyperplasia, which were more obvious when benign prostatic hyperplasia, There was a positive correlation between size and size (P <0.05). The parameters of the external gland artery had no significant difference (P> 0.05). The average values of RI in normal control group, chronic prostatitis group and benign prostatic hyperplasia group were 0.52, 0.57, 0.68 respectively. Conclusion: When chronic prostatitis and benign prostatic hyperplasia, the supply of prostatic gland blood increases and the blood flow resistance increases
