I admitted myself into the hospital in June of 2012 because I felt so spaced out. Later, the day of admittal, my daughter told me that my creatin level was at a near record level of 14 (I believe). I was in for about 7-days before being released to go back ome - and the target was I would be released only after the creatin level dropped into a certain range.
I know the above sounds like no detail was available, but I remember a renal diet was high emphasized. And (not your fathers case), I had a nefrostomy tube put in for my right kidney and a stent for the left kidney. It has been a year now with the above kidney function aides, and every time I get a specific blood test for my kidney function, my creatin level has been close to or within normal range.
My particular reasons for kidney failure or weakness has been - advanced prostate cancer that metastasized into the area of at least the right kidney. However, the thought here is that the nefrostomy tube has worked - and while dialysis was considered by a medical team last year, they thought "let's try this first"!
This might be an option for your Dad!!!!
While a nefrostomy tube is something of an annoyance, it is not painful. Its maintenance is that of being changed every three to four months ideally - and that's as a day patient by a Radiologist - a simple procedure not usually requiring an anesthetic. And the nefrostomy bag needs to be changed every 4 to 8-weeks - and it's a 10-minute change easily done by the patient including adjustments. And finally, there is a special dressing for a nesfrostomy tube that needs to be changed weekly - one option for that is thru a hospital ambulatory service - about a 15-minute change including vitals taken and not including travel time.
If a nefrostomy tube would be an option for him - it would be a minimal interference of the quality of life. It certainly seems much less so than dialysis to me.
I wish you and your Father well.
