Every month I have a nurse come in to change my suprapubic catheter. Whether there is a right way, wrong way or it doesn't matter way, I need to find out if her way is causing my chronic uti's...........

The very first thing she does is deflate the balloon, pull the catheter out, then she goes about getting things set up for the new one. In the meantime (at least 5 minutes or better) I am laying there with no catheter. Is this a good way for bacteria to enter the stoma? After checking the balloon on the new one she starts putting on the solution that comes with the kit around the catheter site before inserting. I always believed that when you take out the old one you should insert the new one right away? Does it matter? Should you put the solution on before you pull out the old one? Is there a correct way it should be done or it just doesn't matter?
