You can expect a higher stabile creatinine after nephrectomy
You can expect that your creatinine level will increase after total nephrectomy. Have you had a renography performed? This can help clarify if the function of your "healthy" kidney is sufficient. If not, you will probably require dialysis after your operation.
Hope this helps.
