Problems solved by technology

[0002] Ureteral stenosis is a common disease in urological surgery. Long-term ureteral stenosis will have a serious impact on kidney function, causing hydronephrosis in mild cases, and renal function damage in severe cases. At present, open or laparoscopic surgery is usually used for ureteroplasty, but this Surgical trauma is relatively large, requiring high intraoperative experience and technology, and postoperative urinary fistula, anastomotic restenosis or incision infection are prone to occur; The method of internal expansion and double-J tube placement for the treatment of ureteral stenosis has been widely used. This operation has the advantages of simple operation, short hospital stay, less trauma, and quick recovery. And it is beneficial to the repair of ureteral mucosa, which has gradually been recognized by clinicians. However, the diameter of the implanted double J-shaped tube is generally small (diameter less than 3mm), and the expansion capacity is limited. The benign ureteral stricture often needs to be expanded repeatedly. Long-term indwelling double J tubes can easily induce urinary salt deposition, which in turn leads to ureteral urinary tract infection or obstruction
[0003] The existing patent number is 201220596709.9, and the patent name is "ureteral dilatation renal cavity drainage tube" applied to the ureter, the balloon is a single balloon, only for fixation

Embodiment Construction

[0026] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0027] Referring to the accompanying drawings, it can be known that the method for using the ureteral double balloon drainage tube is characterized in that it comprises the following steps:

[0028] Step 1: after routine percutaneous puncture of hydrops to dilate the renal pelvis 9 calyces, introduce a guide wire through the ureteral stricture 8, and then introduce a ureteral double-balloon drainage tube 6 through the guide wire;

[0029] Step 2: Inject contrast agent through the external port 3.3 of the fork-shaped injection seat 3 connected to the urine drainage cavity, make sure that the proximal side hole 1.2 of the urine drainage cavit...

Abstract

The invention discloses a method of using a ureter double saccule drainage tube. The method comprises the steps that after renal pelvis and renal calyces are dilated through conventional percutaneous hydronephrosis, a guide wire is imported to pass through a ureteral stenosis structure, the ureter double saccule drainage tube is imported through the guide wire; a radiocontrast agent is injected through an external connector of a fork-shaped injection base and is connected with a urine drainage cavity; when the ureteral stenosis structure is at the upper segment of the ureter, the second saccule is located in the ureteral stenosis structure, and the first saccule is located in the ureter; when the ureteral stenosis structure is at the lower segment of the ureter, the first saccule is located in the ureteral stenosis structure, and the second saccule is located in the ureter; the radiocontrast agent is injected through an external connector connected with the first saccule and the external connector connected with the second saccule of the fork-shaped injection base to fill the first saccule and the second saccule; the ureter double saccule drainage tube is fixed on the body surface. The ureter double saccule drainage tube has the advantages of being effective in draining urine, relieving hydronephrosis and expanding continuously the ureteral stenosis structure. The invention also discloses a double saccule drainage tube structure for the method of using the ureter double saccule drainage tube.

Description

technical field [0001] The invention relates to the technical field of medical equipment, more specifically, it relates to a method for using a ureteral double-balloon drainage tube.
