Re: 47 yo, Stage 3b CKD, GFR 34 Cr 198. Thank you for your response to my questions regarding “ACKD”, my apologies for not specifying this acronym; is in reference to Acquired Cystic Kidney Disease. 3 yrs ago I only had a few small cysts during a stone search CT and now they’ve taken over the entire interior of both organs. I’m looking for links, studies, or journals referencing the effects of Acquired Cystic Disease in pre-dialysis cases. I understand it’s caused by the CKD rather than dialysis, and can occur before treatments begin. I am trying to research in what ways will having both kidneys already completely full of aqcuired cysts, as well as the usual stones and calcium pools may affect my treatment options and outcomes. As most cases don’t advance to this level until several years into treatment. I’m not finding any information regarding cases of fully developed ACKD in pre-treatment patients. Thank you for the links and information regarding cardiovascular issues related to CKD. My nephrologist recommendation to see a neurologist and cardiologist are well explained in the links you provided. Thank you for spending your time with this blog helping CKD patients this is a wonder resource and help to our community.

Acquired cystic kidney disease is generally a benign disease. It is caused by the chronic kidney disease (CKD) and as people age, the cysts become more numerous. It is very common. About 40% of the population will show cysts in … Continue reading

Hi Doctor, In Oct/18, I had abdominal ultrasound and my right kidney has an upper cortical echogenic nodule measuring 0.9 x 0.8 cm. I had another US on May 1st of this year and it grew to 1.8 x 1.7 cm. I was told by my doctor I need another US in 6 months. Do I have to be concerned about the increased of the cyst size?

A cyst and a nodule are not the same thing. A cyst is usually round and filled with fluid. A nodule is solid tissue. An enlarging nodule should be carefully followed and if it continues to grow, should be evaluated … Continue reading

What is meant by left kidney small in size measuring 1.6* 1 cm with few small cyst (4 in no) of size 2-4 mm for a 4 month old baby? Is it dangerous?

I am an adult nephrologist and I do not have expertise regarding infants and children. You should discuss this result with your pediatrician or a pediatric Urologist.

I’ve had two renal ultrasounds done to rule out kidney problems related to high blood pressure. On both of those ultrasounds, a renal cyst was discovered on the left kidney. However, it doesn’t appear on KUB or on CT scan (both done to rule out obstruction from stones, which coincidentally also do not show up on any sort of x-ray.) What sort of cyst would appear on ultrasound and be measurable but not appear on any other imaging studies? Someone suggested endometriosis, but my nephrologist has shot that theory down. I do have a history of adhesions. Another theory was artifact, but would an artifact be measurable and have characteristics? Thank you!

A plain Kidney Ureter Bladder (KUB) x-ray film and Computerized Tomography (CT) scan of kidneys are not very good at visualizing cysts. In fact, a KUB can only pick up very large cysts and then not very well. The ultrasound … Continue reading

Hello doctor, I had an abdominal and pelvic CT scan with contrast a couple of months ago and I would like know the meaning of these findings in more layman’s terms. Thank you. “Kidneys: bilateral renal hypodensities, too small to characterized. No hydronephrosis or nephrolithiasis. Symmetric bilateral nephrograms. No enhancing renal masses.”

I am unable to make a specific diagnosis based on the information that you present. The minimum level of resolution for a contrasted Computerized Tomographic (CT) examination is about 1 centimeter depending on the power of the CT scanner. Hence, … Continue reading

I am an Indian male of 73+ yrs of age. I retired from civil service in India more than 13 years ago and living in Kolkata (previously, Calcutta) with my wife. Though I have a sedentary life style since retirement, I had a very hectic and stressful life during my entire service period of nearly 35 years. I have kidney cysts for long years, first detected in USG nearly 20 yrs ago. They were small in size, at that time about 2cm in diameter. Ever since the cysts were present in all the imaging, USG, CT scans and KUB done many times during this period. They never caused any trouble like pain etc during all these years. Recently, the size has increased to about 4cm in an USG done a month ago. But, there is no pain or any other problem still now. Is it indicative of any serious problem? Please, advise what to do.

If these cysts have been described as simple cysts, no treatment is required. I’m not sure why you needed to have repeat testing as cysts of the kidney are quite common. About 4 out of 10 people develop simple cysts … Continue reading

Had an US of RUQ. Have renal cyst. Right kidney: “10.0 x 5.0 x 5.8 cm. Renal parenchyma is normal in echogenicity and cortical thickness. Hydronephrosis, calculus is not evident. 3.9 x 4.1 x 3.8 cm cyst lower pole right kidney is seen with single internal septation. There is similar morphology to previous examination. Previously this measured up to 2.8 cm. Free fluid in the abdomen is not seen.” Should I be concerned? My doctor wasn’t. Having mild pain RUQ/noGB and mid back. Thanks.

I cannot make a specific diagnosis based on the information that you provide. If the cyst has an internal septation, I commonly recommend a follow up ultrasound in 6 to 12 months or consultation with a urologist. From your description, … Continue reading

MRI of lubar spine without contrast revealed T2 hyperintense right renal lesions (perhaps renal cysts?), and right hydronephrosis measuring 1.9 cm. Is this significant enough to see a nephrologist? Thank you.

A Magnetic Resonance Imaging (MRI) scan is a very difficult scan to interpret for cysts of the kidney. I suggest consultation with a urologist. A urologist is best trained to evaluate both the obstruction and the question of a lesion … Continue reading

KIDNEYS AND URETERS: There are several simple cysts in the right kidney. In addition, in the lateral aspect of the lower pole of the right kidney, there is a subtle 2.3 x 2.4 x 2.2 cm mass. This is new from 06/10/2014. There is an exophytic peripherally hyperattenuating focus from the inferior pole of the left kidney, exophytic. This measures up to approximately 1.3 cm in the coronal plane as opposed to 0.9 cm on 06/10/2014. Nephrograms are symmetric without hydroureteronephrosis. There is contrast in the collecting system limiting evaluation for calculi. Please put in simple language for us. We were told husband has cancer. Thank you!

It is difficult to interpret someone else’s interpretation. It is best to review the radiologic films personally. The report mentions simple cysts which are benign cysts of the kidney and very common. These cysts are not a concern. There is … Continue reading

Hello doctor! I am 24 years old and I have several kidney cysts in both kidneys. I did a CT scan and an MRI for other reasons and I found out I had several small cysts on both of them. I don’t have any symptoms and I don’t have anyone in my family with a kidney disease that I know of. Am really worried. Is it normal to have several cysts at my age? Answering my questions would be a big help. Thank you very much!

At age 24, you should have less than three cysts on your kidneys. If there are more than three cysts and the cysts are simple cysts, then you may have polycystic kidney disease. I suggest that you discuss this with … Continue reading
