Balloon catheter indwelling catheterization of patients who need to bring the gospel in clinical applications more widely, but with the increase of its application, catheter removal difficult situations are also increasingly common. Especially long-term indwelling catheters, and sometimes will cause the aging of the rubber balloon lumen obstruction, forced removal may cause serious complications.

1.clinical data
From December 1992 to April 1999 , has a total of seven cases encountered in patients with occlusion balloon catheter balloon , catheter indwelling time in 3-8 days range. 5 cases were more than 4 weeks .
Our hospital urology right pelvic fracture urethral rupture in patients using indwelling catheter method 6 to 8 weeks , significantly reduced the incidence of urethral stricture . His theory is based on: pelvic fracture takes 6 to 8 weeks to stabilize, premature removal of the catheter will be tortuous urethra , dislocation , deformation, urethral realignment of the high incidence of postoperative urethral stricture .
2 Methods and Results
For seven cases of bladder obstruction patients, we were taken to stretch, water, cut, puncture the operating procedures , can relatively smooth removal of the catheter . One patient only lightly rotating stretch, balloon occlusion smooth once again , the liquid inside the balloon can be successfully extracted , removal of the catheter ; 1 case of unidirectional valve balloon catheter can only be unable to draw water , to keep the balloon 140ml when filled to within a balloon rupture, removal of the catheter ; 2.cases in the past at the cut urethral catheter, cyst fluid ends immediately ejected from the balloon catheter , the catheter with a hemostat fixed and unplug ; 1 case female patients in the treatment method is invalid, insert your fingers into the vagina, fixed airbags, 1cm suprapubic puncture percutaneous fine needle elongated balloon , removal of the catheter ; 2 patients in the B-guided , above the pubic bone to elongate needle puncture airbags, removal of the catheter . [ Medical Education Network collected more ]
The balloon catheter almost throughout the entire catheter lumen fine , and the catheter is made ​​of rubber , easy to aging , resulting in luminal obstruction , the airbag can not be successfully evacuated . To the removal of the catheter difficult. Gently pull the catheter rotation , sometimes you can make adhesions to restore the lumen patency , allowing easy extraction of the liquid capsule . Most prone to occlusion balloon catheter is the site of catheter Y-shaped bifurcation , where the smallest lumen balloon catheter , another point of view , in the production , is also vulnerable to the formation of nodules , so that the lumen wall is not smooth . Cut the catheter near the urethral orifice , and sometimes you can directly bypass the obstruction site , under the pressure of the air bag , cyst fluid can be automatically ejected . But cut the catheter prior to the proximal catheter must be fixed to prevent catheter retracted into the urethra , resulting in unnecessary trouble.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
