How does a urinary catheter work?
Q: A simple diagram image would be pretty helpful too as I am pretty thick and find it easier to see things which I am learning about!! lol
A: Inserting a urinary catheter is a sterile procedure, meaning that the catheter and the person inserting the catheter need to practice surgical asepsis. The environment in the bladder, including the urine, is sterile, and a break in sterile technique can result in a UTI. The labia or glans penis is cleased, usually with betadine, the tip of the catheter is lubricated, then it's inserted into the urethra. It goes in 6 to 8 inches for a male, and 1.5 - 3 inches for a female (the urethra is much shorter on a female). when the catheter enters the bladder, urine will begin to drain down the tube via gravity. After you get return (urine) you insert the catheter and inflate the balloon of the cathter with 10 ml of normal saline. The inflated balloon is too big to go throught the urethra, and therefore holds the cath in place. It's very important to make sure you get return before inflating the balloon, otherwise it may still be in the urethra and could cause urethral damage.Hospitals are trying to get away from using them unless absolutely necssary because they are notorious for causing UTI's. I looked around for a good diagram, but I didn't really see any, sorry!
Had hysterosalpingogram and radiologist was unable to get catheter in. What does this mean?
Q: I had a Hysterosalpingogram yesterday, and the radiologist was unable to get the catheter inside my uterus. I don't see my regular doctor for a few weeks to discuss the results so I am trying to get info on my own. I am concerned that it is a blockage or something that would not only prevent a natural pregnancy but also artificial insemination or IVF, since those require the catheters as well. Does anyone have any experience with this problem? I am at a loss as to what this means.
A: Hi, I don't think my first answer went through properly so am posting this again. I had a HSG today. They couldn't complete it as the nurse kept saying she could not get the catheter through the 2nd layer of the cervix. She explained that there is the cervix which has a small whole in it, and behind this is a bit like a 2nd cervis if you like, a second layer. Basicaly they have to get the catheter tube through the first whole on the cervix and the the 2nd layer which also has a whole in it. The two holes need to line up so that they can get the tube through both. A bit like threading a piece of cotton through two needles. The nurse could not see the whole in the 2nd layer (must have a whole in it as otherwise how would I have a period - it wouldn't be able to drain). They got another qualified nurse to come in and all in all they attempted it 6 times (ouch). She said just because they couldn't do it does not mean I am infertile, as sperm swim around and find the whole in the 2nd layer. Anyway I left in tears as I have read that having the dye test can kind of "wash" everything and wash out mucous deposits etc and some people then concieve (obviously if there is no other probem spotted). I now have to wait for the NHS nurse to write to the NHS consultant, who splits her surgery between 2 areas. Don;t know how long it will take for her to contact me. The nurse said that the consultant will "probably" re-bbok me in again and give me a local anaesetic so that they can stretch things open a bit more and re-attempt, or try something else - no idea what. I felt very vulernable today, 4 people in the x-ray room with me, although my husband was not allowed in. I am 37, 38 in February and we have been trying for just over a year. I seem to have passed all other hormone tests, and my husband has passed his sperm test, although he rated 50% on mobility of sperm and 50% is the pass mark. They did say that you'd hjave to be superman to even get 70%. it's just a waiting game and so frustating. i qualified to go private for al lmy testing as I had been a member of BUPA for 2 years through my company medical scheme. However, my company has now swapped medical supplier and they will not cover any infertility investigations. It is soul destroying. Everyone around me seems to get pregnant and they only do it once !I have now given up buying Ovulation kits etc as it gets my hopes up to much. The consultant put me in for the HSG but did say at the meeting that as we had been trying for a year, we would have to try for another year before they do anything else. That's ok if you are 21 !!!! I am totally fed up and frustated.
How long does post bladder catheter pain last?
Q: I had a pelvic ulstrasound, and the doctor filled my bladder wth fluid through a bladder catheter. Now, a few hours after it has been taken out urinating in almost unbearable. How long does this pain last?
A: The tissue in your urethra is likely irritated from having the tube inserted and taken out. It may not hurt to call your doctor just to be sure if this is normal or not. If it doesn't stop hurting in a few more hours though, I'd recommend that you go to get it checked out.
