摘　　要：目的探讨经尿道内对比增强超声对尿道狭窄的诊断价值。资料与方法回顾性分析2021年8月—2023年9月在北京大学第三医院行经尿道内对比增强超声检查,并诊断为尿道狭窄的5例男性,分析其影像资料。结果5例患者均出现排尿困难。5例尿道狭窄均为单发,2例狭窄位于尿道球部,1例位于尿道膜部,1例位于尿道舟状窝,1例位于尿道前列腺部。2例狭窄<1 cm,3例狭窄长度为1~2 cm。周围瘢痕厚度均<1 cm。2例合并尿道结石,1例合并尿道憩室和假道。结论经尿道内对比增强超声可以无创评估尿道狭窄的位置、长度、单发/多发、瘢痕厚度、有无尿道断裂、有无憩室、有无假道等。超声医师应掌握经尿道内对比增强超声的操作规范,促进其临床推广。Purpose To explore the value of transurethral contrast-enhanced ultrasound in the diagnosis of urethral strictures.Materials and Methods From August 2021 to September 2023,five male patients diagnosed as urethral stricture by transurethral contrast-enhanced ultrasound in Peking University Third Hospital were retrospectively analyzed,the imaging data were analyzed.Results All the five patients had symptoms of urethral stricture such as dysuria.Five patients with urethral stricture were single.The stricture was located in the bulbar urethra in two cases,in the membranous urethra in one case,in the navicular fossa of urethra in one case,and in the prostatic urethra in one case.The stenosis was less than 1 cm in two cases and ranged from 1 to 2 cm in length in three cases.The thickness of the surrounding scar was less than 1 cm.Two patients were complicated with urethral calculi,and one patient was complicated with urethral diverticulum and false passage.Conclusion Transurethral contrast-enhanced ultrasound can noninvasively assess the location of the urethral stricture,length,single/multiple,scar thickness,presence of urethral rupture,presence of diverticulum,presence of false passage.Sonographers should master its operation standard and promote it in clinical practice.
