I Have An 82 Year Old Mother, She's Had A

I have an 82 year old mother, she's had a stroke, she's diabetic, and she has this bladder problem that is driving her nuts I've had her too several doctors they just put a pessary in to hold the bladder in place (she's had it tied up twice) so now she tells me that it hurts still and she thinks its in the bladder now and so this doctor is really good that put her pessary in told her she needs to see a urologist she's got still some blood in her urine no visible but there, and one more thing she cannot sit down on the toilet to pee she has to kinda stand....I'm worried she's got badder cancer..any advice?
