I am sorry if this has been posted before. My mother has lately started to resist going to the toilet and gets very agitated. So we decided that we will observe her and once in a while ask her if she wants to go to the toilet or walk her close to the toilet and see if she wants to use it. So last night she passed uring at around 7:30 pm and now its 11 am. More than 12 hours. She drank more 1.5 L water yesterday before 7.30pm and around 500mL since morning. She does not have an incontinence problem per se because she can hold and doesn't get wet while sleeping. The only other sign we pick up when her bladder is full is that she gets very restless while talking to this invisible person (she has a problem of delusion). But the moment we take her to the toilet she doesn't want to use it. Ultimately she will pass urine while showering (which she normally doesn't want to take). I think she just does not know when she wants to go. But we also don't want to be too pushy as she becomes very resistant. My question is: How long can one go without passing urine? My search says around 10-12 hours maximum. Is this the early sign of what will be coming soon, that is incontinence problems? I miss those days just four months back, when she was still not well but at least took her shower and went to the toilet regularly.
