Hello welcome to Chat Doctor. I have read your question and understand your concerns. Kidney failure once occurred, can not be recovered, unfortunately. But the important and good thing is the other kidney if functioning well then a person can live at least 40 to 50 years more with single kidney. My advice to you is-1.DO Functional studies for the other kidney now and see how is the other kidney functioning. Your nephrologist will guide you further regarding the same, he will guide you in this regard.2.DO his kidney profile yearly, avoid any sort of painkillers which might harm the remaining kidney.3.Otherwise, he can live normal life, Don't worry. THANK YOU .HAVE A NICE DAY.
