Ascending and descending techniques are used to demonstrate the male anterior urethra. The authors developed an ultrasound approach with the patient compressing his own urethra manually during voiding to achieve distension of the urethra with urine. The subsequent sonourethrography is more accurate than conventional fluoroscopic contrast studies in defining urethral filling defects and is as accurate for the demonstration of strictures. The technique has replaced contrast urethrography at the authors' institutions for the routine evaluation of the anterior urethra.
采用逆行和顺行技术来显示男性前尿道。作者开发了一种超声检查方法，让患者在排尿时手动压迫自己的尿道，以使尿道内充满尿液而扩张。随后的超声尿道造影在确定尿道充盈缺损方面比传统的荧光透视造影研究更准确，在显示尿道狭窄方面同样准确。在作者所在机构，该技术已取代尿道造影用于前尿道的常规评估。
