Falling eGFR aged 20

Posted , 2 users are following.

Hi, I’m a 20 year old female who had a nephectomy (surgical removal of kidney) last June. Around Christmas 2017 I began to have pain in my remaining kidney and in April I was found to have an eGFR of 81 which is mildly impaired but I was told not a major concern. 

I returned for a repeat test in June and my eGFR was 79. 

3.5 weeks by another blood test and my eGFR is 65. 

As I am otherwise fit and healthy and drink approximately 3L of water a day, with a limited salt intake and healthy-low blood pressure I am confused as to why this is happening. 

My GP is concerned due to my age and no apparent triggers for the falling eGFR as well as only having one kidney left and has referred me for an urgent nephrology appointment. 

I’m just wondering if anyone else has been through anything similar and what they found the cause to be? 

Thanks in advance.

    It is quite common for people with a sole kidney to have reduced function.  I’m wondering if your remaining kidney might be trying to find a balance now that it is getting used to being on its own.  However, the pain you are experiencing may be symptomatic of something else going on and certainly that is a big reduction on just 3.5 weeks.  The nephrologist is the expert to ask and good luck with the appointment.
