Hello docor, My father is a CHF patient, he always had normal kidney function levels but suddenly in one month, it got increased. Also, recently he was having 100 pus cells in the urine test. He was having burning too. But until last month it was fine and suddenly these numbers. He was admitted for shortness of breath for edema before two months, when he got admitted also the numbers were perfect now suddenly everything increased creatinine, bun uric acid, etc. What could be the problem? They are saying it is because of CHF but suddenly how it gets increased in a few days?
Hello. Patient with CHF (congestive heart failure) has a baseline tendency for renal dysfunction. Also, the diuretics like Lasix which is on cause renal derangements which are usually reversible. Now in his case, the cause appears to be multifactorial. Over and above the baseline tendency, it is probably a urine infection which has initiated this and his infection was severe. Urine infection alone can cause renal dysfunction and probably it is a precipitating factor. Any infection can worsen CHF, which subsequently needs elevation in dose of diuretics and all of these can cause renal dysfunction. So, it is multifactorial and contribution from all three factors. But good thing is, usually this dysfunction is reversible and settles with time. I hope his urine infection was adequately treated and subsequent urine tests were clear. I hope this helps.
