Infrared thermal imaging showed a warmer right kidney.

In a nutshell:
1) I recommend thermal imaging to everyone, even just for prophylaxis.
2) I am now thinking about kidneys in relation to POIS, this had never crossed my mind so far. 

Infrared thermography is a very easy, quick, and non-invasive way to scan the body for abnormalities. Areas with inflammation simply show up as warmer. The method is cheap as well. I had searched for the word "infrared" here on this forum, but had not found any results, so I guess not many members of the forum have done such a screening and perhaps this would be of interest. 

The infrared camera showed clearly that my right kidney was warmer than my left one, so there is something wrong with it. I was directed to see a nephrologist so they can do an ultrasound. I've never noticed any distinguished symptoms related to kidneys specifically.

I just a did a super quick search online - kidneys are responsible for so many functions, just like the liver. They produce a bunch of hormones, interact with toxins, etc. etc. I also searched this forum for "kidneys" - they have been mentioned here and there but without too much discussion.

Let's see if we get somewhere from here.

Superintresting! We use thermography here to find breascancer as a safer way then mammography. When are you set up for the ultrascan?

The ultrasound did not find anything unusual. Yes, the doctor said there is a sign of some kind of infection that had happened in the past, but nothing to worry about.

Increased blood flow through kidney?

With thermography you can discover inflammation (tissues getting hot and the whole organ is showing red). Its in the tissues, not just increased blow flow through the organ.

With thermography you can discover inflammation.

It's probably inflammation. I experienced similar behaviour in small areas of my leg which felt hotter than surrounding tissue temporarily.
