Hello Thanks for query .Based on the facts that you have posted your father has kidney infection and you are in dilemma whether to for Dialysis or not . Decision regarding need for dialysis entirely depends upon the level of Serum Creatinine in blood . You need to consult qualified Nephrologist for clinical examination and get following basic tests done to confirm the diagnosis. 1) Urine routine and culture. 2) Ultrasound scanning of abdomen and pelvis 3) Renal Function tests 4) serum Electrolytes 4) Excretion of albumin and creatinine in 24 sample of urine This will help to establish the stage of his kidney disease and whether he needs dialysis or can be managed with medications .
