Kidney stone strainer / collector kit
Strong evidence
Catch the stone so a lab can identify the type. Prevention only works well when you know what you formed.
Keep one in every bathroom you use while passing a stone.

My struggle with kidney stones
I started this domain in 2008 with a 10 mm stone at the top of the ureter and three blog posts. This is the field guide that should have sat next to them.
What you can do from here
Know the type
Calcium oxalate, calcium phosphate, uric acid, struvite, cystine — diet and meds change with the crystal.
Read the guide
Survive the pass
Heat, fluids, NSAIDs if you can take them, a strainer, and a hard line for when the ER is the answer.
Read the guide
Change the chemistry
2.5 liters of urine a day, sodium under 2,300 mg, calcium with meals, citrus citrate.

Home remedies, graded
Lemon juice earns a seat. Apple cider vinegar does not dissolve a lodged stone. Chanca piedra is traditional.

When home is not enough
Shock wave, ureteroscopy, PCNL — what each is for, and what recovery actually feels like.
Read the guide
Hydration and triage tools
A water target for hot climates and a symptom checklist that does not sugarcoat emergencies.

The kit I keep on the shelf
Every item maps to a recommendation on this site. No “kidney cleanse tea.” No mystery detox. Large Amazon buttons so you are not hunting for a tiny link.
See the full kitLarge marked water bottle (64–128 oz)
Strong evidence
The single best prevention tool is urine volume. A marked bottle makes 2.5–3 liters a day visible instead of hopeful.

Supportive care
Heat relaxes flank and abdominal muscle spasm and is one of the few home measures that reliably takes the edge off colic.
View on AmazonMoonstone Stone Stopper drink mix (lemonade)
Moderate evidence
Urologist-developed alkali citrate mix aimed at raising urine citrate and volume — the two chemistry levers that matter most for calcium oxalate stones.
This is not a prescription potassium citrate tablet. Ask your clinician before combining with other potassium products.
View on Amazon100% lemon juice (no sugar)
Moderate evidence
Lemon juice is a practical food source of citrate. Studies used roughly 85 mL (about 1/3 cup) of lemon juice per day, diluted.
View on AmazonNOW Potassium Citrate 99 mg capsules
Moderate evidence
Dietary citrate supports urine citrate. OTC doses are far below prescription Urocit-K; useful as a food-level adjunct, not a substitute for prescribed alkali.
Do not start potassium supplements if you have kidney disease or take ACE inhibitors / potassium-sparing diuretics unless a clinician says so.
