I realize this post is a bit old.
I had a kidney infection before and used UT Vibrance powder. It worked! It's main ingredient is d-mannose. I know that it is able to detach e. Coli from the kidney walls.
I've also used parsley. You just use a cluster of fresh parsley, boil it, and drink as tea. That one I felt things moving in my kidneys--probably oxalate crystals. (And I know where my kidneys are since I've had an infection.)
There's a lady named Hulda Clark. I'll link her book. She has a product for kidney cleanse. She recommends this as part of her protocol which involves killing off parasites and cleansing the liver.
I found it intriguing that she mentioned parasites attacking/ residing in the kidneys. (She has a lot of interesting facts about parasites, bacteria, and toxins all residing together.)
I saw in one of your other posts that you had used wormwood, etc. I just wanted to add that I also used a homemade tincture of wormwood, clove, and black walnut for parasites, but this did not kill my liver flukes. The rife machine did that. Just a theory, but it's possible parasites could be in your kidneys but didn't get killed by the parasite tincture.
Another thing you can do is use a rife machine (also called a frequency generator). The cost is about $25. You would just place the electrodes on your kidneys. It is capable of killing off various microbes and parasites.
I purchased a frequency generator from ali express (little white one--function generator DDS 100) that was $13.
You'll need:
--BNC cable with alligator clips
--electrode/ tens pads
(I purchased those off eBay.)
I used directions from Hulda Clark in her book The Cure for all Disease
www.scribd.com/document/291985758/Dr-Hulda-Clark-The-Cure-for-All-Diseases
--generator set to square waveform
--turn up amplifier knob
--set positive offset knob 1/4 of the way
--7 minutes "zapping", 20 minutes rest, repeat 2 more times
-- do daily sessions for 2 weeks or more, until no further improvement
She used 1500 or 25000 frequency. Her zapper on her website used 32000 alternating with 33000.
I personally used frequency 500000. (Be aware some electrodes can give small burns using this high of frequency.)
Hulda Clark's method using the "positive offset" allows you to broadly zap and kill viruses, parasites, microbes without needing the exact frequency for each individual bug. (You can place the electrodes over various body areas. Some areas may be too deep for it to fully penetrate. Hulda Clark does recommend using something internally as well as externally--ex. parasite tincture and zap the parasites with the frequency generator.)
