Hello and welcome to HCM..
Thank you for posting your query..
I am really sorry to know the health condition of your dad but don't worry with
dialysis he should be fine..
I read your question completely and have understood it well enough..
Being a surgeon, we encounter so many such cases..
Please do this thing immediately..
1. Restrict his fluid intake to the recommended one.. Less than 750 ml..
Please do it.. Down test the diseased
kidney. Not good..
Shall address all your worries..
2.
Creatinine pre and post dialysis looks pretty normal.
Suggest you not to get carried away by normal creatinine post dialysis.
Remember, it's POST dialysis..
3. And as I told you, his increasing urine output is because he's consuming more amont of fluid than recommended one..
Hope this helps you...
Take care of your dad, very few people do that including you. I'm really happy for this..
God bless you..
And in case you need any further assistance, please let me know. I'm there for you..
