Fluids, Diet, and Meds for Common Stones

The most common kind of stone former has no systemic disease as a cause of stones – ‘idiopathic’ stone former means that. Being most common, their treatments rank highest for all physicians who treat stone formers.

These articles include the treatment trials.

    Hi, My 13 year old son has been struggling with anxiety which lead us to consult with a nutrition specialist who recommended the Organic Acids Test – Nutritional and metabolic profile. This nutrition person just today referred to pediatrician for his oxalate levels. This OAT urine test revealed my son’s values of Glycolic 210 (Range 18-81), and Oxalic 232 (Range 8.9-67). He is generally healthy, no medication, just dietary supplements. He may be lactose intolerant and we have been avoiding dairy. Celiac negative. He has been underweight since he has been 4 years old. He weighs 70 lbs. I have been busy reading everything with your name on it and my question is how at risk are his kidneys ? What levels of oxalate determine hyperoxaluria? How do we safely get rid of this oxalate? I suspect it is diet related. We thought we were eating well but it turns out most of foods I now have discovered are high in oxalate. Regards, Kim

      Hi Kim, If the lab is accurate and urine oxalate is really 232 mg/d, this needs to be corrected immediately. As you can guess, eliminate all high oxalate foods and recheck. If it is all diet, then the diet must be extreme in both low calcium and high oxalate because a value so high is beyond anything I have ever seen from diet alone. Move quickly! Regards, Fred Coe

    I find your articles very informative and interesting, thank you. I am a calcium phosphate stone former and have type 1 renal tubular acidosis and medullary sponge kidney on both sides. In my 24hr urine tests despite being on potassium citrate I still show 0mg in a 24hr period. My nephrologist has told me to stop taking them as they aren’t working. I also take sodium bicarbonate but it has only been a month so do not yet know if it is effective. Do you have any advice for someone in my position? I drink 4L of water a day, low sodium and low animal protein as well. I feel a little discouraged as I currently have 12 stones between 3mm and 9mm. My last stone landed me in the hospital with sepsis for three weeks. Thank you for any advice you my offer.

      Hi Katie, I gather you have both a high urine pH and low urine citrate AND low serum bicarbonate. If so, the many calcifications in your kidneys are not MSK but rather tubule plugging. MSK patients form calcium oxalate stones. If your blood bicarbonate is normal, then you just have CaP stones. If your urine calcium is over 150 mg, I would consider low sodium diet and even chlorthalidone to lower it along with ample potassium chloride so you do not get potassium depleted. Your physician is entirely responsible for your care, I have not seen your actual data, so all you can do with my comment is ask him/her if it is at all useful. Regards, Fred Coe

    Dear Dr. Coe, I’d like to try a stone breaker product (active ingredient is CHANCA PIEDRA) for my stones. What to you advise on this ingredient? My last stone breakdown was as follows.
    20% calcium oxalate monohydrate,
    60% calcium oxalate dihydrate, and
    20% calcium phosphate (hydroxy- and carbonate- apatite).
    Thanks so much.

      Hi t.jo, I have read about this stuff and see little real evidence and a lot of hype. Your stone is not uncommon, and this stuff is promoted as a way to ‘dissolve’ them. I doubt it does anything but enrich the people who sell it. I have long meant to write about it, but it is a wearying thing to take on commercial stuff like this and show how mediocre the underlying data are. So negative a way to spend time! As for my advice, I know of no harm, and suspect it is without value. Regards, Fred Coe
