Thanks for the query.
BUN of 152 and creatinine
of 6.2 indicate a severe degree of renal failure
At this point the consultanat nephrologist
is the best person to decide about dialysis
and from the above labs it appears to be the preferred choice at this moment.
You need to speak to your doctor and he can review your other lab parameters. These can help us determine if the dialysis is going to be termporary or permanent. Also he can look for any reversible cause which might be treated with medicines.
Hope this helps
