摘要
目的: 探讨双平面经直肠超声的二维灰阶和彩色多普勒成像在诊断良性前列腺增生 (BPH)中的应用价值。方法: 192例BPH患者与 50例正常人均进行常规经腹和经直肠超声检查。测量前列腺与移行区的 3个径,计算移行区体积与总体积的比值即移行区指数(TZI);观察前列腺内的血流分布情况,测量血流参数,并计算与TZI的相关性。 结果: 增生前列腺发生囊性变、钙结石和射精管囊肿的概率以及内部动脉血流的收缩期峰值流速 (PSV)和阻力指数(RI)均显著高于正常人;除了钙结石,双平面经直肠超声对以上病理改变的显示率均显著高于经腹超声检查;增生前列腺的TZI与PSV、RI和脉冲指数(PI)呈正相关。 结论: 双平面经直肠超声与经腹超声相比可以更清晰地显示前列腺内部正常及病理结构,同时,PSV、RI和PI可以协助诊断BPH以及判断前列腺的增生程度。
Objective: To discuss the value of grey scale ultrasonography and color Doppler of bi-planar transrectal ultrasound (TRUS) on the diagnosis of hyperplasia prostate gland (HPG). Methods: One hundred and ninety-two patients with HPG and 50 control subjects underwent abdominal ultrasound and TRUS examinations. The width (W), depth (D) and length (L) of the prostates and transitional zones were respectively measured. Each transitional zone index (TZI), i.e., the ratio of the transitional zone volume to the total prostate volume was calculated. Meanwhile, we observed the blood flow distribution in the prostates, calculated the parameters of hemodynamics such as peak systolic velocity (PSV), resistance index (RI) and pulse index (PI), and analyzed their correlations with TZI. Results: The revealing rates of cystic formation, calcium calculus and ejaculatory cyst and PSV, RI of arterial vessels in HPG were all significantly higher in the HPG patients than in the control subjects, and the revealing rates of all the above pathological changes but calcium calculus by TRUS were significantly higher than by abdominal examination. TZI of HPG was positively correlated with PSV, RI and PI. Conclusion: Bi-planar TRUS can clearly display the normal and pathological structure of the prostate. And PSV, RI and PI may aid in the diagnosis of HPG and the assessment of the degree of prostatic proliferation. Natl J Androl,2005,11(3):191-194
