Hello, I have CKD stage 3, microscopic blood in urine. My urologist ordered CT scan w/o contrast and then mentioned maybe a cytology in which contrast would be used. He did not seem concerned about using contrast. Just a bit concerned myself. What are your thoughts please?

If contrast is to be used for a computerized tomogram (CT) scan, the risks and benefits of the contrast should be discussed with you. I do not know anything about the use of contrast for “cytology”.  This does not make … Continue reading

My 72 yr old husband went to ER 8/31/19 for severe back pain, suspected kidney stone. Scans did not show a kidney stone and they thought he had passed it. Blood tests performed at that time showed Serum Creatinine 1.41; Blood Urea Nitrogen 22; MDRD GFR calculated for over 70 years of age was 1.41. Blood tests one month later on 09/30/19 showed Creatinine 1.91; Blood Urea Nitrogen 31; and MDRD GFR calculated 37. Still having back pain and saw Urologist on 10/09/19 who did an X-Ray and ultrasound and found no kidney stone. Blood tests that day were Creatinine 1.89, Blood Urea Nitrogen 37; and MDRD GFR 1.89. With the numbers on these blood tests, I wonder if he should see a kidney specialist. Another symptom (I don’t know if it’s related to the kidneys) is he has had swelling in his groin and legs the last few months and has a red rash on his legs. Swelling is now down to his feet. No one seems to know reason for the swelling. What are your thoughts?

I am unable to make a specific diagnosis based on the information that you present.  Back pain is an uncommon way for kidney disease to present.  It is possible that this represents some form of kidney disease, but I cannot … Continue reading

I am a 31 year old female with PCKD. My question is how soon can I be put on the transplant list? I have frequent recurring UTIs and kidney stones. My kidney function is still in the 90’s.

Polycystic kidney disease (PCKD) is a slowly progressive disease.  You should not require kidney transplantation until your estimated glomerular filtration rate (eGFR) is less than 20 milliliters per minute per 1.73 meters squared.  The eGFR would need to be less … Continue reading

I am a male of 55 yr. I am a diabetic and high BP patient too. Diabetes was seen 12 yr earlier and high BP was seen from last year. Currently hydronephrosis was detected in ultrasound with 10mm loss of parenchyma with left kidney swollen. X ray also shows the swollen kidney. So what do you suggest? Should I remove the left kidney or leave it as it is? Note* no kidney stone was detected in my whole life and my RFT test is normal.

I am a nephrologist and I have no surgical expertise.  A urologist is a surgeon and deals with surgical treatment of the kidney and lower urinary tract.  I suggest that you consult with a urologist about your situation.

I was first diagnosed with hyper paranoidism (I will assume hyperparathyroidism). Once that was resolved and I was still getting kidney stones, my nephrologist diagnosed me with having incomplete dRTA without kidney disease (a fuzzy diagnosis, I know) with a mix of both calcium oxalate and (mostly) calcium phosphate stones. My brother and father have had several stones, but not like me. I have had probably 300+ stones within 3-4 years (2 per week for a long while). I take chlorthalidone 25 mg daily and two potassium chloride 20 meq daily plus I’m on a low-oxalate and low-phosphorus diet. Everything is in control now. My nephrologist is very good, but how can I know for sure if I have this disease? I know the treatment is same, but I’m still curious because it is so rare. Also, do I need to be taking citrate (I tried potassium citrate and it wasn’t enough). All my urine and blood levels are within normal now except my oxalates are sometimes too high. One last question, is their a list of food and food values that include both oxalates and phosphates? Thank you for your thoughts and consideration. I was diagnosed in May 2013.

The diagnosis of renal tubular acidosis (RTA) can be a very difficult one and sometimes involves acid challenge testing and collection of urine for 24 or 48 hours.  In some cases, you may also need to perform a 24 or … Continue reading

Sir, I m 30 yrs old and recently I was suffering with kidney stone both side. Now stones has been cleared but creatinine is still 1.6 and blood pressure is also 160/120. Now I m taking one tablet daily and BP is under control. Sir, please tell me what should I do for better kidney and BP.

For stone disease and chronic kidney disease (CKD), a low salt DASH diet should be followed.  You should limit sodium intake to less than 2000 milligrams per day.  This will decrease the risk of stone disease and help to control … Continue reading

Hi, I am 44 yrs old. I have had kidney issues since I was a kid. I had a urinary reflux problem that damaged my kidneys and a lot of UTI’s. Since I was 16, I started getting kidneys stones in my left kidney and now I get them in both and still get multiple UTI’s every year. I was told when I was younger that my left kidney was 30% functioning and the right was 80%. In saying that, my right kidney is hypertrophied and measuring 13.3 cm and is medullary sponge kidney. My left kidney has diffuse atrophy and measures 8.1 cm. Over the last 4 years I had more issues with the kidney stones mainly on the left side and each time they act up I seem to get very ill with an UTI infection and have elevated temperature despite the use of antibiotics. I always get told the same story by my urologist and nephrologist the “keep drinking more fluids and continue the low oxalate diet”. I am told they will pass on their own as they are all under 5 millimeters. Unfortunately, the only ones I seem to pass are slightly bigger than a grain of salt and I suffer for weeks to months before anything is done. My Creatinine is 75 umol/L and my GFR is 84 ml/min. What I’m wondering, is it worth considering a left nephrectomy in this case? The reason I ask is a nephrologist that I saw as a teenager had recommended that, once I was done having children. My current nephrologist stated it is such a major surgery and that wouldn’t be considered unless I get a lot of kidney stones and a lot of UTI’s; I guess he never really looked at my chart very well. I’ve only been seeing this doctor just over a year. At the beginning of the year out of 40 days that I was to work I was only able to work 15 days and I had the lithotripsy done in April and now again I’ve been off work for 2 1/2 weeks with UTI and multiple stones, 1 of which is 4 mm. I also have a large family history of kidney stones on my mom’s side out of 12 siblings and my grandparents 8 out of 14 have had stones. I look forward to hearing your thoughts.

I am a nephrologist and I have no surgical expertise. Hence, I am unable to comment on whether a left nephrectomy should be done. In patients with stone disease, removing one kidney is often associated with an increase in passage … Continue reading

Hello. I have pain & bloating right under my L rib cage & a “bowling ball” feeling there when I stand. An ultrasound this week has discovered a 2cm stone. A previous stone hurt in my mid back, but I don’t have back pain this time. Could the stone be the only cause for my symptoms? Thank you.

Kidney stones do cause back pain in various locations. I would suggest that you have further consultation with your physician about your symptoms and the kidney stone.

I have a 9mm stone lodged in my left ureter. Causing me to feel fatigued, nausea, pain in my flank, rash on my ribs, burning urination, and slight headaches. At times I feel a slight throbbing right under the ribs on my higher back. A) I am scheduled for a urologist appointment in 17 days… B) My health insurance coverage kicks in in 15 days… C) I was advised by a Chronic Kidney Stone patient to take up to 50k IU of Vitamin D3 to break the stones. Should I? Is there any validity to that? D) Should I run to the ER? Thanks.

I do not know of any information about vitamin D supplementation causing stones to break or dislodge. I would not recommend this. If you are vitamin D deficient, then vitamin D supplementation could be necessary to prevent future kidney stones, … Continue reading

Dear Doctor: I had to do a 24-hour urine collection for a kidney stone analysis and collected 2,900ml of urine during that period. For the 17 hours I was awake, I collected 1,500ml of urine, but during the seven hours after I went to bed I collected 1,400ml. Is it normal for kidney output to increase during sleep, or does this indicate a problem of some sort? Thank you in advance for your response.

It likely represents your hydration and fluid intake during the day and especially evening hours and then your urine output catches up with you at night. This does not represent any disease process. In fact, most kidney stones are started … Continue reading
