A week ago I went to the ER with what I thought was a kidney stone attack. I’m 80 yrs old and in general good health. Some years ago I had an attack and had one or two stones removed from a kidney. In the ER they did a scan to show to their Urologist. The scan showed I had a very large cyst on my right kidney and that cyst, depending upon scan view “slice” showed it surrounding a stone. The left kidney was free of any shown cysts and normal. The scan showed the cyst to be round and symmetrical, not tumor like. At the moment I’m awaiting a decision from the Urologist re how to proceed. The Urologist told me initially upon looking at the scan, “it looks like a very difficult case”. The Urologist has since taken ultrasound views of the affected kidney area supposedly to show and review with a Radiologist. From what I’m thinking, the treatment plan might be for the Radiologist to aspirate the cyst then the Urologist to “roof” the cyst and then go in and remove the stone. After the initial stone, intense pain, I took a couple of pain killers and the severe pain subsided and it’s been “low grade” ever since. Sitting or bending certain ways can bring on the pain, but otherwise it’s continually like a mild tooth ache. It seems to be taking time for my Urologist to come up with a treatment plan and date for a procedure. Is the treatment for my condition one that requires any experience/training beyond what a typical Urologist and Radiologist would be doing on a regular basis. Are there any Medicare _+ Medigap insurance issues covering such a procedure.

I am a nephrologist and have no surgical expertise.  A urologist is a surgeon and has expertise in the surgical treatment of kidney stones and complex cysts of the kidney.  I suggest that you continue to consult with your urologist. … Continue reading

I am writing on behalf of a friend from Turkmenistan. My friend is studying in China and does not know much English, which complicates things. But from what I can gather, his father is having a problem with kidney stones. His father has only one kidney, and last year he had an operation to remove his kidney stones. However, according to my friend, the operation was not that successful because many kidney stones still remain. His father does not want an operation, but wants to know if there is medicine or any other treatment he can have to get rid of the kidney stones. According to my friend, the type of kidney stones his father has are called “korall.” He sent me some photos, and it looks like this many has had a LOT of kidney stones removed already. Do you have any advice for my friend and his father, or do you have any suggestions as to what my next step should be in finding an answer for him?

I am not familiar with “korall” stones.  The problem that you pose is a urological problem.  Consultation with a urologist, who is a surgeon, would be most appropriate. For more information on kidney stones click here:

Hello, My 9 year old son recently had an renal ultrasound to look for kidney stones, etc. We don’t follow up with the nephrologist for over a month, and I’m curious about ultrasound report. The nurse told me on the phone that he didn’t have kidney stones, and this is what the report actually says: 1. Mild right pelviectasis in the prone position only (7 mm). 2. Otherwise normal sonographic appearance of the kidneys. No definite calcifications are seen. In the prone position only, there is mild right pelviectasis (SFU grade 1 bordering on 2) with AP diameter of the pelvis measuring 7 mm. I assume the pelviectasis isn’t serious since the nurse didn’t bring it up on the phone, but never having heard the term before, I tried to research it. The only references I can find refer to fetal pelviectasis, and I can’t find anything about this condition in a 9 year old child. I’m also curious about it only being seen in the prone position. Does this point to the possibility of some sort of blockage, or is it likely just a physiological finding? Is it unusual in a child his age?

Pelviectasis (also called pelvocaliectasis) merely means a separation of the collecting system or pelvis of the kidney detected by the ultrasound device.  It does not suggest any disease, unless there are symptoms or signs of blockage and none are described. … Continue reading

I have a single right kidney with congenital ureter deformations. I have had an infection off and on for over 20 years, averaging to one every 3 to 4 months. I have also developed kidney stones having two lithotripsy surgeries within 3 years, and looking at another within the next month. I was put on a potassium/calcium treatment that I developed a skin rash from something pertaining to that. I am also anemic. I also religiously drink my water. My question is, what can I do diet wise besides cranberry to improve my kidney health?

I am unable to make medical treatment recommendations without performing a complete history and physical examination.  I am a strong advocate for the DASH diet.  The DASH diet can decrease the tendency for stone formation when coupled with a low … Continue reading

I get kidney stones on a regular basis that pass on there own. I seem to have pain in my foot associated with the stones, almost like a burning sensation. Is this normal or could it be caused by something else?

I do not know why you should experience foot pain associated with kidney stones.  This does not make sense.  Patients with gout may get painful joints and also kidney stones that come from gout stones.  I can not explain the … Continue reading

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?

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: You should … Continue reading
