I am a caregiver to a man that goes to dialysis 3 days a week but I am wondering if he has been misdiagnosed. He urinates all the time and 5 out of the last 8 that he’s been, they have taken no liquid from him. I find this a huge red flag?

Urine output does not equal kidney function.  Almost all of my patients on dialysis make some urine on a daily basis.  The question regarding fluid removal has to do with the amount of fluid that he accumulates between dialysis sessions.  Some forms of chronic kidney disease (CKD) continue to produce urine but the blood cleaning functions of the kidney are not adequate.  Laboratory studies are performed once monthly to make sure that dialysis is appropriate and adequate for patients at the kidney center.  If you have concerns, either your patient or his family should express concerns with the nephrologist who is caring for him.
