my husband has protein in his urine the renal doctor says there is no cure. best hope is a gradual worsening of this disease. he is in stage 3 now, but has not gotten worse in almost a year. how serious is this disease? How many stages are there? His Dr. said you don t get worse because that means if you do worsen you are dead. My husband is 63 and is retired now because of his high pressure job. His blood pressure is great now. What is a realistic expectation of lifetime left we will share? childhood sweethearts
