肾盂输尿管支架引流在输尿管和肾盂手术的应用上,有很大好处,其目的在使输尿管切口得到休息、促进愈合、防止漏尿、避免发生狭窄及弯曲,同时可以引流有积水的肾盂,以消除感染。其适应症如下:1.作输尿管切开术后,特别是输尿管有狭窄倾向,或局部组织脆弱,使缝合不甚完善者。2.作输尿管吻合或整形术后,及作输尿管膀胱吻合术后。3.在输尿管受意外损伤,特别是曾被误扎,纵使即时解除结扎线,仍有可能发生坏死,形成瘘管或发生狭窄。3.作肾盂切开木后,尤其当肾盂积水比较显著时。过去我们在作输尿管手术后没有放置支架引流,虽然大多数可获满意愈合,但少数患者发生了合并 The use of ureteropelvic stent drainage in the ureter and renal pelvis surgery has great benefits, its purpose is to make the ureter incision rest, promote healing, to prevent leakage, to avoid stenosis and bending, and can drain the hydronephrosis of the pelvis to Eliminate infection. The indications are as follows: 1 for ureteral incision, especially ureteral stenosis tends to be, or fragile local tissue, the suture is not perfect. 2. For ureteral anastomosis or plastic surgery, and for ureteral bladder anastomosis. Unexpected injury in the ureter, in particular, has been accidentally straightened, even if the immediate lifting of the ligature, there may still be necrosis, the formation of fistula or stenosis. 3. For the pelvis incision wood, especially when the hydronephrosis is more significant. In the past, we did not have stenting drainage after ureteral surgery, and although most were satisfactorily healed, a few patients had merged
