1988年10月至1989年10月,我院对120例患者经直肠B超行下尿路动态观察128次,试图通过此法探讨扩大对下尿路疾患的诊断能力,现报告如下。一、仪器与方法使用日产Hitachi EUB-400型超声诊断仪(枪形探头频率5MHz)。术前嘱病人饮水800ml。待膀胱充盈后取仰卧位,先用线阵探头行腹部探查,了解膀胱一般情况,测量前列腺的横径;再改侧卧位,将直肠探头插入肛门,使探头窗朝向腹侧中线,至能清晰看到膀胱、前列腺、尿道,测量前列腺的前后径及上下径。按椭圆形求积公式得到前列腺体积。然后在病人尿道口置以集尿器,令病人排
From October 1988 to October 1989, 120 patients underwent dynamic observation of transurethral B-mode lower urinary tract dynamic observation 128 times, trying to explore this method to expand the diagnosis of lower urinary tract disorders, are as follows. First, instruments and methods Nissan Hitachi EUB-400 ultrasonic diagnostic apparatus (gun probe frequency 5MHz). Instruct the patient before drinking water 800ml. After filling the bladder to supine position, the first line probe with abdominal exploration, to understand the general situation of the bladder, measuring the transverse diameter of the prostate; then change the lateral position, the rectal probe inserted into the anus, the probe window toward the ventral midline, Clearly see the bladder, prostate, urethra, measuring the anteroposterior diameter and the diameter of the prostate. Press the ellipse quadrature formula to get the prostate volume. Then in the patient’s urethra set urine collector, the patient row
