What happened to me was the following:
I begin to have more urgency and frequency when urinating.
Then I felt tired. In fact, I thought I was getting the flu.
I had a low temperature. Then burning started when I urinated.
I decided this was the same symptoms I was treated for about a month after surgery. I was told then it appeared to be a bladder infection but didn't show up as very much of one in tests.
I went to my own primary care doc who gave me Levaquin. He too thought it was a bladder infection but it didn't show on the urine dip stick test.
The next day I was worse, not better. Temp went to 103.
The next morning I felt still like I had the flu so since it was Saturday, we called the doc on call. He felt it sounded more like Kidneys so asked us to go to urgent care. The doc there tested for bladder and kidney and it was neither. But a blood test showed infection. So they did a CT Scan and found the fluid.
The reason I had to be re cathed was the fluid sack was pushing on the bladder wall. They wanted the bladder completely collasped when they stuck the needle in to put the drain line in.
I didn't want that again, but my doc said they had switched brands of cathethers since I had it three months ago and these are better. I have to admit, it wasn't even hardly noticeable. Needless to say, I still didn't beg to keep it in when they wanted to remove it!!!!!
Thankfully, I work in a huge medical facility and even though UCSF is not part of our system, the docs refer there quite a lot. Also to the Stanford Med Clinics. So it is no problem to be a patient (or employee for that matter) and have an outside doc.
I am glad my cancer doc is only about an hour and 45 minutes away. The biggest problem is just the hassle of a big city. But that is OK as all but one time we have used the commuter train, subways, and buses so San Francisco's hills, teeny streets, and parking aren't a problem. And we can avoid the $24.00 a day parking garage fee at the hospital.
I go back on Monday for a recheck. If I remember I will ask my docs how often this happens and how likely it is it will just absorb and go away.
Don't stress over this. As I said before, it really isn't a big obstacle. More of a hassle thing than anything else.
