在尿道狭窄的诊断年和治疗中逆行尿道造影是标准的显像方法,但难以确定准确的狭窄长度和疤痕形成深度;又因其是一种二维图象,狭窄的影象会随阴茎的伸展和病人的体位而变化。作者采用逆行注水超声尿道图检查尿道狭窄,能显著改进常规的放射学检查效果。总共17例拟诊尿道狭窄的病人作了上述两种检查。先行逆行尿道造影,见到狭窄后即作超声尿道图(检查者不知道X线诊断)。超声尿道图的方法是:在前尿道插入F12号带气囊的导尿管,气囊注水约2ml,然后在尿道内注入10～15ml无菌盐水。选择阴茎背侧作为超声探测部位以减少近视野的假象。前尿道检查完毕后,改为阴囊部探测后尿道,见到狭窄部位和测定其长度后,再
Retrograde urethrography is a standard imaging method in the diagnosis of urethral stricture and in treatment, but it is difficult to determine the exact length of the stenosis and the depth of scar formation. Because it is a two-dimensional image, a narrow image of the urethra Stretching and the patient’s position and change. The authors used retrograde injection of ultrasound urethra urethra stenosis, can significantly improve the routine radiological examination results. A total of 17 cases were diagnosed urethral stricture patients made the above two checks. First retrograde urethral angiography, see the stenosis after ultrasound urethra (the examiner does not know the X-ray diagnosis). Ultrasound urethra map method is: in the anterior urethral catheterization F12 with balloon catheter, balloon injection of about 2ml, and then injected into the urethra 10 ~ 15ml sterile saline. Select the dorsal penis as the ultrasound detection site to reduce the illusion of near vision. After the former urethral examination was completed, the urethra was changed to detect the scrotum, to see the stenosis and to determine the length, and then
