Problems solved by technology

[0003] Usually, the replacement of the ostomy tube is completed under DSA fluoroscopy with the cooperation of the guide wire. However, this method has a certain failure rate and infection rate; in addition, if the ostomy tube is not smooth, it will significantly prolong the operation under X-ray exposure. time, increasing the radiation damage of patients and operators; if the ostomy tube is blocked, the guide wire cannot pass through the ostomy tube, resulting in failure of the operation. no drainage effect

Embodiment Construction

[0016] like figure 1 As shown, a drainage tube replacement method for failure of conventional methods includes the following steps:

[0017] 1) The patient lies supine on the DSA treatment bed, selects the patient's position according to the position of the patient's drainage tube 1, performs local disinfection, spreads a towel, disinfects the drainage tube, and cuts off the fixing line that is fixed to the skin outside the drainage tube 1;

[0018] 2) Insert a 0.035 guide wire through the gap between the drainage tube 1 and the skin. Under fluoroscopy, the guide wire 2 is inserted into the ureter along the direction of the drainage tube 1 or coiled in the renal pelvis 3, then the guide wire 2 is fixed, and the drainage tube 1 is directly Cut off, and slowly pull out the drainage tube 1 under fluoroscopy;

[0019] 3) Introduce a new drainage tube 1 through the guide wire 2, withdraw the guide wire 2, tighten the fixed line at the tail end of the drainage tube 1 and lock it, s...

Abstract

The invention discloses a drainage tube replacing method aiming at the failure of a conventional method. According to the drainage tube replacing method, a guide wire is introduced to a sinus tract formed by a gap between a drainage tube and the skin, and then the drainage tube is cut off and directly pulled out. With the drainage tube replacing method, the exposure time of X rays is shortened byone time or more, so that the ray injuries caused to a patient and an operator are reduced, and further, the patient and the operator are benefited. For the drainage tube replacing method, while the exposure time of X rays is reduced, no differences exist between the method provided by the invention and the existing conventional method in the aspects of the technical success rate and the complications.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a method for replacing a drainage tube, in particular to a method for replacing a drainage tube for failure of conventional methods. Background technique [0002] Percutaneous nephrostomy (PCN) is an effective method for the treatment of upper urinary tract obstruction, hydronephrosis / hydronephrosis, urinary extravasation and urinary fistula, and is widely used clinically. However, when the patient needs to keep the nephrostomy tube for drainage treatment for a long time, all patients need to replace the nephrostomy tube regularly, which can effectively avoid a series of complications caused by the blockage of the nephrostomy tube. [0003] Usually, the replacement of the ostomy tube is completed under DSA fluoroscopy with the cooperation of the guide wire. However, this method has a certain failure rate and infection rate; in addition, if the ostomy tube is not smooth, it will sig...
