目的：我们比较了临床相关性的放射性尿道造影与超声尿道造影评价男性尿道狭窄。材料和方法：从2002年至2004年，93名男子被称为我们的机构尿道狭窄。通过常规排尿性膀胱尿道造影、逆行尿道造影、灰阶和彩色多普勒超声尿道造影对患者进行评估。对于超声尿道成像，使用扩展视野技术获得整个前尿道的1个图像。在所有情况下，尿道进行了评估膀胱镜或开放手术。放射性尿道造影和超声尿道造影的结果进行了比较，膀胱镜检查或手术findings.Results：所有狭窄进行了评估和治疗膀胱镜与视觉内尿道切开术（34%）或开放手术（66%），这允许比较的能力，每项研究预测手术狭窄长度。超声尿道造影在所有病例中正确识别了狭窄及其部位，而放射性尿道造影产生了2个假阴性结果。经统计学处理，两种方法测量的狭窄长度有显著性差异（相关系数0.72 vs 0.92，P < 0.005）。通过放射性尿道造影测量的平均± SD狭窄长度为1.5 ± 1.3 cm，通过超声尿道造影测量的平均± SD狭窄长度为2.1 ± 0.9 cm。比较放射性尿道造影和超声尿道造影狭窄长度与手术长度显示阴茎尿道有良好的相关性（相关系数0.91对0.98），而相关性较差，发现在球尿道（相关系数0.65对0.92）。使用西门子Sonoline（R）Elegra扩展视野技术的灰阶和彩色多普勒超声尿道成像是确定男性尿道狭窄的一种有前途的工具。它似乎是上级放射性尿道造影治疗计划。
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 (R) Elegra is a promising tool for defining male urethral strictures. It seems to be superior to radio urethrography for treatment planning.
