目的分析对上尿路系统直接采取超声造影检查的临床意义。方法 20例上尿路梗阻的患者,于经皮穿刺引流术中由引流管内直接给予肾盂注射SonoVue共2ml,加上20~40ml的生理盐水,比较脉冲序列(CPS)造影模式中连续观察其造影剂的强回声在肾盂向膀肤与输尿管的运动过程,结束造影之后吸出尿路中的液体,反复冲洗直到造影剂的强回声显著减弱。结果经过造影超声检查后,发现输尿管出现肿瘤的共2例,出现破裂1例,出现开口异位2例。结论临床上经皮穿刺上尿路顺行造影超声检查可以诊断出一般超声和彩色多普勒超声中无法诊断的尿路梗阻等疾病,并且不会造成尿路并发症出现。
Objective To analyze the clinical significance of direct contrast echocardiography in the upper urinary tract. Methods Twenty patients with upper urinary tract obstruction underwent percutaneous drainage with direct injection of 2 ml SonoVue into the renal pelvis and 20 ~ 40 ml normal saline. Contrast-enhanced pulse-sequence (CPS) Strong echogenic agent in the renal pelvis to the movement of the urethra and the skin, after the end of the contrast sucked out of the urinary tract fluid, repeatedly washed until the echogenic contrast echoes significantly weakened. Results After contrast echocardiography, ureter tumors were found in 2 cases, rupture occurred in 1 case, 2 cases of open ectopic. Conclusions Clinical percutaneous puncture of the upper urinary tract along with contrast ultrasonography can diagnose such diseases as urinary tract obstruction which can not be diagnosed in general ultrasonography and color Doppler ultrasonography and will not cause urinary complications.
