My eGFR has always been between 51 and 53. This month test results shows eGFR of 45. Serum creatinine has always been around 135, this months results are showing 155. Please can you let me know if I need to be worried or if this is an known level of variation. I am already following a healthy diet. Any other suggestions that you can provide to improve my health?
The estimated glomerular filtration rate (eGFR) between 45 and 60 milliliters per minute per 1.73 meters squared is Stage 3a chronic kidney disease (CKD). These numbers are potentially normal variation and the only way to tell may be to wait … Continue reading →
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 →
At my most recent check up, my microalbumin levels were very elevated. My level was 33. My creatinine was normal, and my ratio was normal. However, I am concerned about the high level of albumin. I do not have diabetes or high blood pressure, but I am overweight. Do I have kidney disease?
I am unable to provide a specific diagnosis of chronic kidney disease (CKD). If the urinary ratio of albumin to creatinine in the urine is normal, then an elevated albumin concentration in the urine is of no significance. I suggest … Continue reading →
What kind of pain medication can kidney patients take that is safe and won’t damage your kidneys any further?
Acetaminophen (brand name Tylenol) is safe for patients with chronic kidney disease (CKD) as long as doses are under 3000 milligrams per day. Higher doses can cause liver injury. Aspirin can be taken for short periods of time and not … Continue reading →
Canadian health care guidelines allows a CKD patient not to have dialysis even if the eGFR is 6. They say CKD patients can live a normal life even at that low number without dialysis or kidney transplant. Does America health care go by this guideline?
I begin dialysis when I think that dialysis will benefit my patient. This is not based on any number, but rather , will dialysis improve the symptoms of my patient to the point that the patient is willing to undergo … Continue reading →
I am a 39 years old. Kindly interpret my result: sugar and protein negative Rbc 2-5 (1+) Pus cells 0- 1 occasional. All were blank except for amorphous urates and squamous cells which are occassional and bacteria few. Thank you.
The information that you supply suggests that this is a urinalysis result. There are a small number of red blood cells in the urine, but I am unable to make a specific diagnosis based on this information. I suggest that … Continue reading →
As a Nephrologist how high could you tolerate the serum creatinine number being before you would seriously consider dialysis or kidney transplant for a CKD patient?
As a nephrologist, I use the serum creatinine as an estimate of kidney function, but the decision to start dialysis requires that I listen to my patient and have them tell me what symptoms they are having and whether dialysis … Continue reading →
Dr Spry, are there different ways of measuring egfr? Following the national foundation’s link my son’s egfr is 46 (with wt and height and 41 without wt and height). But according to his doctor it is 37. His creatinine is 2.1, age 30 and height 70 inches and wt 165.
The estimated glomerular filtration rate (eGFR) can be calculated in at least four different ways in adults and three different ways in children. This does not include the calculation of the estimated creatinine clearance with a Cockcroft Gault equation. I … Continue reading →
5 months back, I had a kidney stone operation of the right kidney and I find that right kidney is functioning 9 ℅ and left kidney is functioning 42℅. Now after 5 months, I have very bad pains in my right kidney seems very heavy. Bad smell in the urine. What should I do? I have already gone thru surgery twice of my right kidney. Please help.
The problem that you describe is a urological problem and I am a nephrologist. I do not perform surgery. You should consult with your urologist. For more information on kidney stones click here:
I understand the kidneys functions are to remove toxins from the blood. This will probably sound like a very strange question, however, I have no one else to ask. If someone has injected themselves with bacteria and instead of causing an abscess it gets absorbed, does that mean that bacteria gets filtered through the kidney, and can that cause a kidney infection? Can the kidney infection then lead to cysts (which have recently shown up on ultrasound) and if so, are they likely to be considered “simple” or polycystic? Also, this person is currently being treated for kidney infections and psychiatric disorders.
Bacteria in the blood can cause infection in the kidneys, but I am not sure this will lead to cysts in the kidney. Bacteria in the kidney causes acute pyelonephritis and this typically results in scars in the kidney rather … Continue reading →
