I found out today that my 96 yr old mom with a large rectal tumor has fecal material coming out of her urinary tract. This was discovered because the hospice nurse tried to re-insert mother's Foley catheter which keeps coming out. The hospice nurse believes this indicates that a fistula has developed between the rectum and the bladder. Has anyone else seen this and what might happen next? From what the nurse said, mom is not in any pain at this point (that she's verbalizing). Thanks for any insight you guys can provide.
