经造瘘管超声造影在轻度肾积水肾造瘘术中的应用

Application of Contrast-enhanced Ultrasound via Fistula in Nephrostomy for Mild Hydronephrosis

目的探讨经造瘘管超声造影在轻度肾积水患者肾造瘘中的应用价值。资料与方法 53例轻度肾积水(肾积水<1.5cm)患者随机分为研究组及对照组,研究组27例使用经造瘘管SonoVue超声造影动态监测肾造瘘过程,对照组26例使用常规超声监测肾造瘘过程,对两组患者造瘘效果进行对照研究。结果研究组造瘘成功率为96.3%,对照组为69.2%,研究组肾造瘘成功率明显高于对照组,差异有统计学意义(χ2=5.097,P<0.05);对照组出现1例引流管持续出血,3例肾周血肿,而研究组未出现明显并发症。结论经造瘘管超声造影动态监测在提高轻度肾积水患者肾造瘘成功率及减少并发症方面有较高的临床价值。

Purpose To explore the clinical value of contrast-enhanced ultrasound （CEUS） via the fistula in nephrostomy for patients with mild hydronephrosis. Materials and Methods Fifty-three patients with mild hydronephrosis （〈1.5 cm） were randornly divided into study group （27 patients） and control group （26 patients）. SonoVue CEUS was used in the study group to monitor the process of nephrostomy while routine ultrasound was employed in the control group, and the outcome was compared. Results The success rate of study group was significantly higher than that of control group （96.3% and 69.2%. respectively, 2＇-~=5.097, P〈0.05）; in the control group, continuous bleeding in drainage tube occurred in 1 case and perirenal hematoma occurred in 3 cases, whilst no obvious complications occurred in the study group. Conclusion CEUS via the fistula has high clinical value in monitoring nephrostomy for patients with mild hydronephrosis and can improve success rate and reduce its complications.
