I had a urinalysis done in my pc’s office on 8/17/2018, results were acute cystitis without hematuria. Then my dermatologist sent me to quest diagnostics on 8/22/2018 for another urine test and feces culture. Quest said the feces culture (the next day) was NEG. for shiga toxins, eia w/rfl to E.coli 0157 culture, no campylobacter, or salmonella and shigella isolated. HOWEVER, they did say I had the e coli in my urine and that’s what caused my infection. I say if E. coli is in urine, it’s also in stool culture. I have 2 microscopes, 1 LED that you plug into your pc, and 1 regular light microscope. The test (dip stick) in the pc’s office read pos. for nitrates, protein 30, leukocytes >65 and gfr of 51, oh and they (pc’s office) forgot to call prescription in so 3 days later I received Bactrim, AND Cipro-which I asked for in the first place and the trainee (resident) told me no, to the Cipro, he was calling in the Bactrim. OMG I almost had a heart attack when I saw the gfr #. Should I be worried? No one else seemed to be. I am 61 and over the years I have had at least 5 kidney infections, including one hospitalization (I was pregnant) key here is a microscope is a microscope. I know when I did the stool culture, I looked at my stool and saw many worms, or larvae. I actually didn’t need the microscope. When I put the stool in the container (at home) I made sure to put the largest one on the top. I don’t know how they could have missed that one. Easily seen with the naked eye.

An E. Coli infection in the urine is not the same E. Coli that is being examined for in the stool. The enterotoxic E. Coli (also known as Enterhemorrhagic E. Coli or 0157:H7) is the bacteria being searched for in … Continue reading

I am Indian 63yrs old having weight 68.6kg.and height 5.5 ft. and have no other complications than serum creatinine 6.7mg% and Bun 63.4. My bp is 140/80. and no diabetic. Till to day I have no sign of any illness. On one occasion, when I went to native faced severe sun temp.at 47, and felt that my body became dry since then my appetite is affected and very recently on 22nd September on blood test my Hb found to be lowered at 8.9 and size of kidney became 7.20×4.5 RK and 7×4.2LK with above blood reports. Doctor diagnosed it may be a chronic renal failure[?]. I have no problem with urine, urine clearance and no pains any where in body but developed nausea for food. Is it sign of CKD or chronic renal failure? Difference between chronic disease and failure? Is there any way to make up Hgb at normal level? Does reduction in size of kidney reduces functional ability? If yes, what can be done to bring it at normal? Is Magnetic Biotherapies worth to undergo? Please advise me at the earliest to avoid any further complications in this matter. You may suggest any best place if treatment is to undertake.

Symptoms such as loss of appetite, nausea and progressive anemia with weakness are common with advanced kidney disease.  The anemia can be treated by use of Erythropoiesis Stimulating Agents (ESA’s).  The other symptoms may be more difficult to treat. I … Continue reading

I can’t get anyone in my dialysis unit to listen to me. I keep telling everyone that I don’t retain water. I still urinate at least as much as I drink, which is 8oz of coffee and about a 20 oz glass of water some days. I have asked other patients how they feel after dialysis and most say better. I feel awful, sometimes I want to eat everything but always I will sleep until the next day and could sleep more. My blood work always looks perfect, a liitle lie on calcium, protein and iron and if I make blood cells it is very few. (Before ESRD my blood sugar meter would many times say to use real blood and not work). My BS is in control. My doctor says do you think you are gaining weight and no I don’t. I am kinda stuck at 94 kilos. I believe they are dehydrating me to the point of tiredness or I am still too low on red blood cells.

I am not able to make a recommendation without performing a complete history and physical examination.  In my experience, most patients on in-center dialysis three times weekly, have symptoms of fatigue and need to rest or sleep for some time … Continue reading

Dear Sir, with many thanks for your kind website. Please be informed that I’ve have had kidney transplantation 16 years ago. The donor was my brother. ( my brother and I have one same father, but our mothers are different.) From 3.5 years, the creatinine has raised little by little. Now it’s 4.5 but BUN is 30. I have repeated blood analysis several times at different labs, and all the results were same. Honestly, my doctor is confused. She says that such creatinine must normally lead to higher BUN like 100 or more. Would you please let me know do you have idea in this regard?

The blood urea nitrogen (BUN) has many factors that can effect the value, so that a serum creatinine of 4.5 may not necessarily be associated with a markedly elevated BUN test.  For example, if you are a very muscular man, … Continue reading

Hi Dr, over a year ago my husband underwent a Radical Cystectomy (RC) after 6 weeks of chemo and radiation. He has two constructed ureters, since then he’s been septic twice, with multiple hospital stays as recent as August along with multiple stent replacements. The right stent fell out twice and now he only has left stent which was replaced Wednesday because he started getting ill (always same symptoms). He’s been on Cipro for 3 weeks with 7 more days to go. He now has CKD primarily generating from left kidney. GFR is at 50. Prior to the RC he Was a strong, healthy, vital man with the blood work of an 18 year old. We live in Florida but got 5 opinions prior to making our decision. His bladder cancer was aggressive but did not penetrate the wall, did not spread and is not a cancer he can pass on to his children. Can you help us with any guidance or information? We eat aloe, the actual meat of the plant daily. Are daily doses of honey and lemon good for his CKD. What else can I do for him to prevent and/or improve his left kidney?

It would appear that the cause of the chronic kidney disease (CKD) is his bladder changes with infection and obstruction of the kidney.  Hence, the treatment is best carried out by his urologist.  This is not a primary kidney disease … Continue reading

I am a 60 yr old (white) female. I had 6 stones of various size 1mm to 9mm removed from my left kidney last year. The stone analysis report shows 40% calcium oxalate monohydrate, 20% calcium oxalate dihydrate and 40% calcium phosphate. Now, one year later, a CT scan revealed 2 more in the same kidney. What is causing my body to make these stones? And what can I do to correct this?

I am unable to provide a specific diagnosis based on the information that you provide. You will likely need to be evaluated by a nephrologist and have a 24 or 48 hour urine collection for stone supersaturation index.  This will … Continue reading

All this information on kidney disease has me wondering just how much our diets in the US are affecting us negatively. My friend, age 48 was recently diagnosed with Stage 4 CKD. It was a shock as she really didn’t feel or look sick. She was mildly fatigue. It was because her hands were cramping up she sought medical treatment. She is being told a respiratory illness caused her CKD. She is not diabetic nor does she have HBP. Her nephrologist said she doesn’t have to be overly concerned with protein and phosphates more the sodium. I personally feel her whole diet should change. While her GFR remains at 17 her creatinine is rising. She is currently on tapering dose of steroid, insulin to treat high glucose (due to steroid) and high blood pressure med. Why wouldn’t adhering to a kidney diet help this condition? I think there is such a prevalence of this disease due to fast foods, processed foods and over consumption of sodas and sedentary lifestyle!

I am a strong advocate for the DASH diet for patients with chronic kidney disease (CKD).  However, with Stage 4 CKD and an estimated glomerular filtration rate (eGFR) of 17 milliliters per minute per 1.73 meters squared, she may need … Continue reading

I was recently diagnosed with AKI from heat exhaustion. Since then my kidney function has gone back to normal. It has been 2 months since the incident. I’m still have left back pain, dizziness, fatigue, lack of sleep, only 6 hours per week, headaches, but my doctor is ready to release me back to work because my kidney function are normal now. Do you think I could perform at work?

I always have low GFR (as low as 45) and elevated creatinine with fasting labs, but normal GFR and creatinine if non-fasting. Thoughts as to why this is? I’m still waiting for an explanation from my physician. Nml renal US, chronic HTN, not always well controlled. Thank you.

I do not know of any reason why kidney function testing should be different between fasting and non-fasting specimens. These tests should not be affected by whether or not you have anything to eat or drink.
