Abstract

PURPOSE

We compared the clinical relevance of radio urethrography with that of sonourethrography for evaluating male urethral strictures.

MATERIALS AND METHODS

From 2002 to 2004, 93 men were referred to our institution for urethral strictures. Patients were evaluated by conventional voiding cystourethrography, retrograde urethrography, and gray scale and color Doppler sonourethrography. For sonourethrography the extended field of view technique was used to obtain 1 image of the whole anterior urethra. In all cases the urethra was evaluated cystoscopically or at open surgery. Radio urethrography and sonourethrography findings were compared with cystoscopy or surgery findings.

RESULTS

All strictures were evaluated and treated cystoscopically with visual internal urethrotomy (34%) or at open operation (66%), which allowed comparison of the ability of each study to predict operative stricture length. Sonourethrography correctly identified the stricture and its site in all cases, whereas radio urethrography yielded 2 false-negative results. There was a significant difference between stricture length measured by radio urethrography compared to that measured by sonourethrography (correlation coefficient 0.72 vs 0.92, p<0.005). Mean+/-SD stricture length measured by radio urethrography was 1.5+/-1.3 cm and by sonourethrography it was 2.1+/-0.9 cm. Comparison of radio urethrography and sonourethrography stricture length with operative lengths demonstrated a good correlation in the penile urethra (correlation coefficient 0.91 vs 0.98), whereas a poor correlation was found in the bulbar urethra (correlation coefficient 0.65 vs 0.92).

CONCLUSIONS

Gray scale and color Doppler sonourethrography using the extended field of view technique with a Siemens Sonoline Elegra is a promising tool for defining male urethral strictures. It seems to be superior to radio urethrography for treatment planning.

摘要

目的

我们比较了放射性尿道造影和超声尿道造影在评估男性尿道狭窄方面的临床相关性。

材料与方法

2002年至2004年，93名男性因尿道狭窄被转诊至我院。患者接受了传统排尿性膀胱尿道造影、逆行尿道造影以及灰阶和彩色多普勒超声尿道造影检查。超声尿道造影采用扩展视野技术获取整个前尿道的1张图像。所有病例均通过膀胱镜检查或开放手术对尿道进行评估。将放射性尿道造影和超声尿道造影的结果与膀胱镜检查或手术结果进行比较。

结果

所有狭窄均通过膀胱镜直视下尿道内切开术（34%）或开放手术（66%）进行评估和治疗，这使得能够比较每项检查预测手术狭窄长度的能力。超声尿道造影在所有病例中均能正确识别狭窄及其部位，而放射性尿道造影出现了2例假阴性结果。放射性尿道造影测量的狭窄长度与超声尿道造影测量的狭窄长度之间存在显著差异（相关系数分别为0.72和0.92, p<0.005）。放射性尿道造影测量的平均±标准差狭窄长度为1.5±1.3 cm，超声尿道造影测量的为2.1±0.9 cm。放射性尿道造影和超声尿道造影测量的狭窄长度与手术长度的比较显示，阴茎尿道的相关性良好（相关系数分别为0.91和0.98），而球部尿道的相关性较差（相关系数分别为0.65和0.92）。
