彩超经直肠检查输尿管中、下段结石的诊断价值

Diagnostic value of TRS-CDU on detecting middle-lower ureterolith

目的 探讨经直肠腔内(THS-CD)观察输尿管中、下段结石的临床价值。方法 对27例肾积水,输尿管上段扩张,经腹超声找不到结石的患者,采用经直肠腔内彩色多普勒超声检查。结果 输尿管盆段与壁段经腹部无法找到,均经直肠清晰显示患侧输尿管及出口处,其扩张程度与结石有关,患侧输尿管结石检出率为100％,输尿管出口喷尿彩图减弱或消失。健侧输尿管有规律的扩张及喷尿彩图的正常出现。结论 TRS-CD能准确地显示输尿管病变及健侧的正常蠕动,方法简单,安全可靠,进一步提高了输尿管中、下段结石的诊断价值。

Purpose To evaluate the clinical value of transrectal color Doppler ultrasound(TRS - CDU) diagnosis of middle - lower ureter calculi, Methods TRS - CDU was performed in 27 case with hydronephrosis or upperureterectasia, all of them no calculi can be detected by routine abdominal color doppler ultrasound. Results Abnormal ureter in all case can be shown sonographic characters, and they had great relation to the size of calculies. The accuracy rate was 100% .The color flushing urine pictures of ureteral opening dispeared or buzzy. Conclusions TRS - CDU can present the disease of middle- lower ureter correctly, and urine flushing from the normal side can be shown clearly. It is of great value in clinical practice for diagnosing ureterolith.
