AIM
To compare the evaluation of urethral stricture disease using ultrasonic urethrography and standard retrograde urethrography (RUG).
METHOD
175 male patients suspected of having urethral stricture disease underwent urethral sonography prior to RUG in a prospective, non-randomized study.
RESULTS
A correct positive diagnosis was established in 98% of the cases; a correct negative diagnosis in 96%. The sensitivity and specificity of urethral ultrasound in detecting urethral strictures were 98% and 96%, respectively.
CONCLUSION
Ultrasound offers a three-dimensional study to evaluate the urethral without exposing the gonads to ionizing radiation. The exact length and depth of a stricture, the severity of the strictured segment as well as the anatomy of the periurethral scars were diagnosed accurately. Urethral ultrasound is a simple, inexpensive and rapid investigation of the urethra which should be the preferred diagnostic procedure in the evaluation of strictures in the anterior urethra of men.
目的
比较超声尿道造影与标准逆行尿道造影（RUG）对尿道狭窄疾病的评估。
方法
在一项前瞻性、非随机研究中，175例疑似患有尿道狭窄疾病的男性患者在进行RUG之前接受了尿道超声检查。
结果
98%的病例确诊为阳性；96%确诊为阴性。尿道超声检测尿道狭窄的敏感性和特异性分别为98%和96%。
结论
超声提供了一种三维研究方法来评估尿道，而无需使性腺暴露于电离辐射。狭窄的确切长度和深度、狭窄段的严重程度以及尿道周围瘢痕的解剖结构都能被准确诊断。尿道超声是一种简单、廉价且快速的尿道检查方法，应成为评估男性前尿道狭窄的首选诊断程序。
