I have a 22mm kidney stone. So what food should I eat to prevent my kidney from stop functioning and live a healthy life??

I commonly recommend the DASH diet for patients with chronic kidney disease (CKD) and kidney stones. The DASH diet is a low salt diet. You can review the DASH diet on our web site at: https://www.kidney.org/atoz/content/Dash_Diet A 22 millimeter stone … Continue reading

I have a stage 3 kidney disease. I was born with one kidney. My remaining kidney has numerous kidney stones and cyst. I just found out the biggest cyst is 7.8 x 5.9 x 6.4 cm. I was diagnosed with Bosniak 2F. This is over half the size of my actual kidney, which is 15.3 cm. I am postmenopausal, but have started experiencing blood in the urine. What would be the prognosis? Can a cyst be surgically removed? Thanks for your response.

The problem that you describe should be evaluated by a urologist. I am a nephrologist and have no surgical expertise. A urologist is a surgeon and deals with complex cysts and stones of the kidney. I recommend that you consult … Continue reading

I have 3 stones in my right kidney, 1 stone in the upper pole 16mm and two in the lower pole. Now my doctor said that we only treated the upper pole stone. We cannot treat lower pole stones but I am not satisfied to leave the stone in my kidney forever.

Kidney stone removal is within the expertise of a urologist. I am a nephrologist and I have no expertise in the surgical management of kidney stones. You will need to seek a second opinion from a urologist. I know that … Continue reading

Calculus of size measuring 3.9 mm in lower pole in right kidney. Can it be cured by medicine or surgery?

A stone that measures 3.9 millimeter (mm) should generally be managed with medical management unless you are having pain. If you are having pain, then you need to consult with a urologist. If you are not having pain, then I … Continue reading

Hello doctor, I was doing some research because of my current diet which is high in sodium. I really enjoy this diet because it allows me to lose weight and to eat foods that I love but are high in sodium so I need an advice with it. I read that too much sodium in the diet could cause kidney disease because the kidney can’t function properly without the appropriate sodium/potassium balance. But too much sodium is not a problem if more potassium is eaten, as long as the potassium eaten is at least double the amount of sodium eaten. Is this correct?

This is not correct. The higher the sodium content of the diet, the greater work the kidney must do to eliminate this salt. High salt diets raise blood pressure, increase the risk of kidney stones, and promote heart disease. It … Continue reading

Hi Doc, I’m a 56 year old aircraft mechanic that has had 74 stones in my life. My question is since you guys can remove a kidney, why can’t you disconnect it at both ends and connect a pump to flush it out? Like a radiator? This way you don’t even have to remove it. Which brings me to my next question. What does the kidney mount to in the body? In other words, is it free floating in the body or is physically attached? Thanks for reading these questions.

The kidney is attached to the rear portion of your abdomen and cannot be readily removed and “flushed”. Urologists have a way of breaking up stones that are present and then the urine that the kidney makes flushes the stones … Continue reading

I have Medullary Sponge Kidney. My urologist says I can take Aleve with a ureter stent. My GP says I shouldn’t take Aleve. What do I do, as the Tylenol does not work for discomfort and the Aleve does? Thanks.

I would tend to side with your Primary Care Physician (PCP) regarding the use of Aleve. The Aleve will decrease your kidney function. Make sure you drink plenty of water to flush the stone fragments out. The pain will likely … Continue reading

My 32 year old stepdaughter has been told that she has medullary sponge kidneys. She’s been suffering from kidney stones and complications from surgery for about 2 years. It appears that MSK is not only quite rare, but often misdiagnosed. Can you tell me where the most knowledgeable and experienced doctors in the US can evaluate her and determine the best treatment plan?

The most comprehensive reference I have found for Medullary Sponge Kidney has been at the National Organization of Rare Diseases and you can access this site at:  https://rarediseases.org/rare-diseases/medullary-sponge-kidney/ We also have a summary page on our web site at:  https://www.kidney.org/atoz/content/medullary-sponge-kidney … Continue reading

Hello sir, my name is Thuta and I’m from Myanmar, previously known as Burma. We’ve got a health issue about my father who suffered a kidney issue but there is no symptoms about disease and the CT scan result told us there’s a flesh cyst inside the kidney and the doctor suggested that it have to remove as soon as possible cause of cancer prospect. So I wanna know removing kidney is only solution or not and if there were any solution, please let me know. My father’d faced with two operations about removing kidney stones in each kidney and the last operation was 2015. If I’ll have a chance, I’m gonna share all of the medical documents about that. With so much thanks d

The question being asked is a surgical and urological question.  I am a nephrologist and I have no surgical expertise.  I cannot accept records on the blog.  You will need to consult with a urologist about whether surgery is indicated. … Continue reading

I was recently told I had proximal renal tubular acidosis. I have had intermittent dull kidney pain for many years. Could never drink alcohol because my kidneys would ache the following day. I never had stones that I know of. I have had two ultrasounds since 2013 that never found stones. I started having limb weakness and muscle fasciculations in 2015. At one point I could not walk right for 17 days. They never figured out what the problem was. They noted slightly low potassium of 3.1 But insisted this would not cause symptoms. 2018 I started having a lot of problems/episodes. Limb weakness, fatigue, vertigo, high heart rate and bouts of high blood pressure. I went to the ER multiple times and they insisted it was panic attacks. But every time they took blood my potassium would be too low. Sometimes I required IV potassium. After a year and a half of this a new internist that consulted a local nephrologist diagnosed me with RTA 2 and was put on potassium until the nephrologist can get me in and get me treated. My concern is the intermittent nature of this. Sometimes my potassium loss is gradual and other times I lose a lot in a short period of time. Sometimes in a matter of hours it can fluctuate quite a bit. I do not know how much fluctuation is normal so any examples would be helpful. I worry about taking this potassium and it getting too high when my kidneys are not wasting potassium. Is that possible? I am on 20 MEQ twice daily. Is there a safer treatment option? Thank you for your time.

Type 2 or proximal renal tubular acidosis (RTA) should be associated with a low serum bicarbonate level and may be associated with a low serum potassium. There are a number of other hypokalemic (low serum potassium) syndromes that include hypokalemic … Continue reading
