I am Sunil Patil.  My kid is just 2 month born baby boy (DOB 10/17/14).  Before birth via sonography it was shown RT Kidney enlarged (33mm) & LT kidney was normal (6mm). On 12/18/14 he had another sonography of the kidney. which showed hydronephrosis with kidney size RT 7.5 x 3.5cm & LT 5.5 x 2.1cm.  Please suggest to me 1) what is the reason of increasing size of kidney?  2) Can it be treated on oral medicine? 3) What precautions to take? 4) Is it necessary to operate for such cases? 

The problem that you present is a urological problem and is usually addressed by a urologist.  I am a nephrologist.  I suggest that you consult with a urologist who is a surgeon and seek an opinion on what can be done. For general information about hydronephrosis please click here.

I underwent lithotripsy today to treat a blocked ureter and kidney stones. I had moderate hydronephrosis and an infection before the procedure. How long does it take a kidney to recover from hydronephrosis and how will I know if it has?

After blockage and infection of the kidney, it may take several weeks before function returns completely to normal.  I would suggest follow up with your physician until the kidney function tests are normal.

I feel pain in my sides and my back early in the morning. Also, when l eat food, my sides hurt. It burns when I urinate.

I cannot provide a diagnosis for your symptoms.  I do not recognize this as a kidney disease.  You could be experiencing bladder disease such as a bladder infection.  I suggest you consult with your primary care physician.

My sister is 38yrs old. Recently, she found out she is HIV positive. After she began the medication, she developed kidney failure. She has been in hospital for three weeks . She could not walk at first. Now, she can at least walk to the bathroom However, the doctors says her kidney failure is due to the medication. Please let me know at what stage should she seek donors and when to start dialysis? How can we help her? What questions should we ask the doctor?

I am unable to provide a specific diagnosis for your sister.  I can only suggest that your sister work with her primary care physician and her nephrologist to develop a treatment plan.  If this is acute kidney injury from the medication, it might be reversible.  If this is chronic kidney disease from the Human Immunodeficiency Virus (HIV), then the kidney disease may be more permanent.  Hence, your sister needs a specific medical diagnosis and treatment plan for her specific kidney disease.

Would major depression prevent a kidney transplant if the patient is under treatment and has their own living donor?

Depressive disorder is very common in chronic kidney disease (CKD), but if major depressive disorder is present, normally the transplant service would consult with a psychiatrist to determine the risks of transplantation.  Medications used at the time of transplantation may pose problems for patients with major depressive disorder and each transplant center must determine the criteria they will use to address this issue.  There is not a nationally recognized guideline for dealing with such problems.  As long as the depression is well controlled with medication, I do not believe it would pose a problem, but psychiatric consultation is best obtained before the transplant is considered with a living donor.

I was treated for Hepatitis C in 2004. My current viral count is zero. Can I donate a kidney to someone who does not have Hepatitis C?

I do not know the answer to this question.  I would have to consult with a hepatologist about your risks of having the Hepatitis C virus come back again.  I have never been involved in a case where this has come up.

My husband is scheduled for a cat scan w/ dye to review leg pain. He has chronic kidney disease w/ GFR of 33. Are these dyes too harmful?

There is some risk of kidney injury with the administration of iodinated contrast dye for a computerized tomogram (CT) scan.  The risks and comparable benefits of the test should be discussed with your husband’s doctor.

What happens to Renal patients that get MRSA?

When a kidney patient gets methacillin resistant Staphylococcus Aureus (MRSA) infection, it should be treated with antibiotics, but the dose of antibiotics should be adjusted for the level of kidney function.  Otherwise, there is no difference in treating the disease in a kidney patient or the general population.

I have a 4.9 centimeter size oncocytoma on my left kidney that started out being 4.5 centimeters in size. A needle biopsy was done and it’s benign. My urologist told me that unless it starts to grow rapidly (at which time another biopsy will be done), the mass can stay on my kidney. Does the mass have anything to do with the way the kidney functions? I also had quite a few large kidney stones. These caused a blockage, a stent insertion, two lithotripsies, stent removal, another blockage and a third lithotripsy. My urologist doesn’t seem too concerned that my EGFR is at 57, although it was in the mid 80s a year ago. Do the stones and lithotripsies cause the numbers to fall? At this point I have followed a low oxalate diet, with good control over my diabetes, but stress makes my blood pressure a bit high right now even with medications. I am stone free and plan to stay that way too.

The oncocytoma should not have any effect on decreasing your kidney function.  Kidney stones, diabetes and high blood pressure will definitely cause decreases in kidney function and these are much more likely causes of the decrease in the estimated glomerular filtration rate (eGFR).  You should also have urine studies to see if you have protein in your urine.

Everytime I get sick my lower back hurts, the more sick I become the worse my lower back is. I have a sinus infection now and went to the doctor this morning. She took a urine sample and said I have blood in my urine but no white blood cells. I’m confused why my kidneys hurt when I’m sick and why there would be blood in my urine when I become ill.

There is a kidney disease known as IgA nephropathy that is characterized by dark urine, blood in the urine and sometimes back pain with fever during illness.  These attacks are called “synpharyngitic episodes”.  If these symptoms persist, you may want to ask your primary care physician for a referral to a nephrologist.
