目的:探讨输尿管支架肾造瘘管在肾盂成形术中内外引流治疗肾盂输尿管连接部梗阻的疗效及方法。方法:对280例肾盂、输尿管连接部梗阻,采用肾盂成形术,留置输尿管支架肾造瘘管内外引流,并观察其效果。结果:270例术后45天拔去输尿管支架肾造瘘管,术后吻合口畅通,无漏尿、发热、泌尿系感染等并发症。另10例术后行顺行肾盂输尿管造影检查,见连接部狭窄,更换输尿管支架肾造瘘管,继续引流支撑45天后,行顺行造影检查,狭窄消失。结论:输尿管支架肾造瘘管临床应用具有操作简单,引流可靠,并发症少,拔管容易,费用较低,患者易接受等优点,值得临床推广应用。
Objective: To investigate the efficacy and methods of ureteropelvic renal fistula in the treatment of renal pelvis and ureteropelvic junction obstruction in pyeloplasty. Methods: 280 cases of renal pelvis, ureter junction obstruction, the use of pyeloplasty, indwelling ureter stent renal fistula drainage, and observe the effect. Results: 270 cases of ureteral stent removed 45 days after operation, the anastomotic opening was smooth, no leakage of urine, fever, urinary tract infection and other complications. The other 10 cases underwent anteroposterior pyelography, see the junction of stenosis, replace the ureteral stent nephrostomy tube, continue drainage support 45 days, the line line imaging, stenosis disappeared. Conclusion: The clinical application of ureteral stent nephrostomy tube has the advantages of simple operation, reliable drainage, less complications, easy extubation, lower cost and patient acceptance. It is worthy of clinical application.
