I was just told by Mom's hospice nurse that she probably has a rectal fistula. Can anyone tell me what to expect?

It's just a guess, but aren't there 'supra pubic' catheters that can be used where a Foley's isn't feasible? I think my late father-in-law had one - your hospice nurse will be able to explain, but in any case I'm sure your poor mother won't be permitted to suffer unnecessarily. My best wishes to you.

Yes, at this point I am just waiting. I kind of expected something like this to occur. My thought is also that infection will worsen (I know she already most certainly has a UTI because she's had a Foley catheter for over 8 months). Now that the catheter apparently cannot be re-inserted, due to growth of tumor or fecal impaction or maybe collapsed urethra wall, she may end up with complete bladder outlet obstruction. It's hard to say what will happen next. Thank you both for your comments. I appreciate your support.

I've done a little searching on this, it is called a colovesical fistula so that is where you need to look for info. It is possible to manage this by simply treating with antibiotics, steroids and other meds.

I've heard of a fistula between the rectum and vagina. This is the first time I've heard of one with the bladder. It would seriously concern me if it was the bladder, because infection couldn't be controlled. At 96 and with a rectal tumor, I know that you are waiting. I wish I had some answer for you, but I don't think there is much you can do beyond what you are doing. It is good that she is not feeling pain.
