I originally posted a question on 1/17/17 about my 9 year old son. I don’t see a way to respond to the reply, but have some more information that might be helpful to others looking for information on the same thing. At his doctor’s request, I was able to scrape some off to take in to the lab, and the stone analysis came back as 65% calcium oxalate dihydrate and 35% carbonate apatite. Additionally, a 24 hour urine test indicated a calcium/creatinine ratio of 245 (normal 30-20-) and an elevated creatinine level of .81 (normal 0.11-0.68). The doctor said for him to follow a low oxalate diet and follow-up with a pediatric nephrologist, which we will. Is it important to find the cause of the high creatinine and calcium rather than just treat the symptom? I remembered that my aunt (would be his great-aunt) died from nephritis at age 7, but don’t know if that would be considered a genetic risk for him that far removed.

I am unable to make any specific diagnosis based on the information that you present.  It is best if you see a pediatric nephrologist and have further testing.  It is possible that he has a genetic kidney stone disease but … Continue reading

About 10 years ago my ex-husband, who has always been in good health, developed hematuria. There was no work up then. About 3 years ago, he developed multiple kidney stones in only the left kidney. He has also experienced multiple episodes of gout. His left kidney has atrophied to 6mm transverse x 8mm AP x 9mm sup-inf-inf. He is on Potassium Citrate 3x daily with Allopurinol. He had shock wave lithotripsy 08/16 with questionable results. A renal US in 11/16 noted again multiple kidneys stones with further atrophy. He has had several more gout attacks with this regime. GFR is 41. I am concerned about damage to kidney from persistent good sized stones. Should they be removed? Would a biopsy be warranted? Why are there stones in only the one kidney? Could it progress to involve the other? There is no family history of kidney disease or gout. Thank you for your help.

The problem that you raise is a urological problem and should be dealt with by a urologist.  I am a nephrologist and have no experience with lithotripsy or surgery.  I suggest that your ex-husband consult with a urologist and determine … Continue reading

I have had a recurring UTI infection. They did a cat scan. I have many kidney stones, the largest being 17 mm x 32 mm. They said there was thinning of the lining of the kidney. I’m guessing from the size of this that the only option left is surgery. Will my kidney lining heal? Is this an extreme case?

The problem that you pose is a urological problem and must be dealt with by a surgeon.  I am a nephrologist and do not perform surgery.  I suggest you consult with a urologist who is a surgeon.  If you have … Continue reading

I am in Kidney Stone prevention mode. My doctor gave me a short list of low, medium and high oxalate foods. However, while trying to research the oxalate content of foods not on the list, I find much conflicting info. My cholesterol is high as well. Some resources say to combine higher oxalate foods with calcium foods. ie cheese and milk which can be high in cholesterol. Can you recommend any books or websites for a patient? I have no medical training and many websites simply confuse me more.

I have not been a fan of low oxalate diets.  They are very difficult to follow and are not very effective.  I suggest you follow a low salt DASH diet.  You can review the DASH diet at:  https://www.nhlbi.nih.gov/health/health-topics/topics/dash You should … Continue reading

My mother has severe pain in right kidney. She went to the doctor for checkup. He asked to have an abdominal ultrasound so after ultrasound, the doctor said that there is 5mm area visualized at middle calyx of right kidney. Please tell me what does this mean and what we can do for it also? My mother is also suffering from hepatitis C, so please tell me.

I cannot interpret the ultrasound examination without examining your mother and seeing the images from the ultrasound.  The ultrasound should be interpreted by the physician who requested the test.  I suggest that you discuss this with the physician who is … Continue reading

I am working on a research paper with my team to propose a treatment for kidney stones. However, while plotting down the main points, we came across a question that is “is there actually a possibility to discover a permanent cure for kidney stones?” And if yes, is this cure applicable on people with risk factors and kidney dysfunction only or is it applicable on people who have kidney stones due to dietary factors?

There are many causes of kidney stones including genetic factors, dietary factors, environmental factors and factors related to kidney disease as well as other systemic diseases.  It will not likely be possible to find a single treatment that will cure … Continue reading

Dear Sir, My question is that I have a stone in my kidney. The stone is seen through CT scan but it is not seen in ultrasound. Doctor suggested lithotripsy. I want to ask can lithotripsy shock damage my kidney or is it safe for kidney stone, or any other way to break kidney stone naturally. Kindly guide me. I am fearing for lithotripsy operation due to its side effect.

I am a nephrologist and do not perform lithotripsy.  This is a problem to be discussed with a urologist.  You should discuss the risks and the benefits of the lithotripsy with your urologist. To learn more about Lithotripsy click here:

A friend ( 60+) has developed kidney failure and was in the waiting list for transplant when a donor is found. However, the hospital ( in the US) has now removed her from the list because they found high level of oxalate in her blood. They do not want to risk a new kidney getting damaged by the oxalate? What can be done to reduce oxalate in the blood ( or something else?) in the hope of potentially allowing her to be placed back in the list for future transplant. Any thoughts/references/ publications to shed some insight on this would be much appreciated.

Elevated oxalate in the blood may have many different causes.  There are a number of diseases such as primary hyperoxalosis and oxaluria that can cause this.  Your friend should consult with an expert in kidney stone disease to learn the … Continue reading
