My husband is in the hospital right now and they are telling us that his kidneys are failing because his blood pressure is extremely high. Can you tell me the symptoms? When we went to the ER, they did a urine test and I noticed that his urine was clear like a glass of water. Is that a sign? He is diabetic and has had kidney problems in the past which has delayed doctors for doing test that involved using dye. How serious will this have to get before they have to put him on dialysis? Is this life threatening?
