Any experience with untreated bladder cancer in a 94 year old?

My dad was diagnosed about a year and a half ago with what they thought was the more aggressive type of bladder cancer. He had a scope test done but we decided against any treatment. So far he has had some periodic hematuria, but otherwise good. He lives alone in his home and has a caregiver come in 5 hours a day. I’m concerned as to how this will play out. We considered assisted living but decided against it due to Covid. I know the bleeding and urinary issues will only increase. Short of having him wear Depends, how can this be managed? He also has dementia
