摘　　要：目的探讨尿路梗阻性肾疾病经造瘘管顺行超声造影的应用价值。方法 43例尿路梗阻患者,经皮肾盂造瘘术后从引流管直接向肾盂内注射造影剂行超声造影,观察造瘘管位置及造影剂向肾盂、输尿管、膀胱流动的连续过程。结果超声造影诊断输尿管通畅15例,通而不畅20例,不通8例。其中诊断造瘘管位置异常2例,肾段小血管出血2例,复杂肾病2例。结论经造瘘管顺行非血管性腔内超声造影可以判断肾造瘘是否成功,同时可判断梗阻性肾疾病的梗阻程度、部位,明确部分病因。Objective To explore the application value of antegrade non-vascular contrast-enhanced ultrasound by the fistula of nephrostomy in diagnosis of obstructive renal disease. Methods 43 patients with urinary tract obstruction were enrolled. After they underwent a percutaneous puncture nephrostomy under uhrasound guidance, SonoVue agents were injected into the renalpelvis via the fistula for performing antegrade non-vascular contrast-enhanced ultrasound. The fistula location was observed. Continuous process of contrast agent to the renalpelvis, ureter and bladder was monitored. Results Antegrade CEUS revealed that the ureteral were unobstructed in 15 cases, partially obstructed in 20 cases and obstructed in 8 cases, including 2 case with fistula abnormal position, 2 cases with angiorhagia of segmenta renalia and 2 cases with complex kidney disease. Conclusion Antegrade non-vascular contrast-enhanced uhrasound by the fistula of nephrostomy can assess whether nephrostomy is successful under ultrasound guidance. It can judge the degree and the location of urinary obstruction and confirm part of obstruction causes.
