Hello and welcome to HCM. As an Urologist,i can understand your anxiety. You should write your mother s age.She s diabetic,has hepatic encephalopathy,Hypertension,with renal failure and just out of coma. That s not a good history to begin with.Dialysis is done in kidney failure ,when the creatinine or potassium rises,or body fluids increase. Urine draining out will be minimal,as kidneys are poorly functioning. She can take only salt and protein restricted foods.Liquids as urine output. It would take about a month for discharge,depending on progress. If you ve any doubts,send the reports to me,as a direct question. Dr.Matthew J. Mangat.
