<human>: Hello Doctor , My sister aged 56 was suffering from urinal infection since last 2 years on and off.. She has been taking medicines for the same . Today her Nephroligist says her left kidney is totally dead non functional and has to be removed within 2-3 months .. My Queries : 1) How come all of a sudden we come to know of this , inspire of regularly visiting a renowned Neohroligist. 2) Can there be any chances of revival of the dead kidney ? 3) If not , then should it be removed / when ? 4 ) what should we do ? Please guide us ? Awaiting an early reply , Thanks and Regards , Santosh Shah
<bot>: Good Day, and thank you for being with Chat Doctor ! A non-functioning kidney can be due to chronic obstruction or chronic infection. non-functioning kidney cannot be revived anymore. If the non-functioning kidney is the cause of your recurrent UTI then it should be removed to prevent UTI and preservation of the remaining good kidney. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/ Chat Doctor.
