Suffering From Alzheimer. Had Many Bladder Infections, Uterus Stretched During Prostate Removal And Having High Voiding

My husband has Alzheime rs. He has had his prostate removed. It was large, but non cancerous. He has had many bladder infections. The neurologist did a cystoscopy and found the ureters were a little constricted because of the large prostrate, and he stretched them during the procedure. He now has me up oh 2 at night. I either get him to use the urinal, or he goes to the bathroom. I have checked his voiding oh 2 during the day, and there is 200 ccs. At night his voiding can be as high as 400-500 and even 700 ccs. Of course then the bed is soaking. I am not getting enough sleep, and unfortunately, he does not remember what he has done.
