I was found to have a 6.8 x 5.6 x 4.7 cm lower pole septated cyst. What are the chances this is a concern for AKA cancer? I’m 58 in good health. The cyst was 1.6 cm in 2009.

The question that you ask is a urological question.  I am a nephrologist and do not deal with cancers of the kidney.  In the case of the septated cyst that you mention, the radiologist should describe the cyst using the … Continue reading

I am currently 24 weeks pregnant. My baby has been diagnosed with BMCDK. I am looking for a doctor who is willing to offer amnioinfusions and provide care with a result not ending in death of the fetus. If you can provide recommendations that would be amazing.

My normal weight is 110 but gained 20lbs from steroids. I urinate often, never had uti, history of kidney stones, treated with lithotripsy. I am not a diabetic. Last creatinine was 1.1.

I´m a female, living in Sweden and is 59 years old. I was diagnosed with renal pelvis TCC, PT2a, grade 3, 8 years ago. I had my left kidney removed and have gone for follow ups since then. When the cancer was discovered I was told that I had a 3 cm cyst in the right kidney. After that the cyst has grown to be 7.5 cm and I have had several infection in the kidney. I’m worried about the growing cyst and the infections in my only kidney and wanted to do something to prevent a acute situation. I took it up with a doctor who wanted me to go to a urologist at the hospital. I have now got the answer from the urologist at the hospital that they think its a normal kidney with no pathological problem. My question is- Is a single kidney with a 7.5 cm cyst in it consider to be a normal kidney? I was worried before and now I feel very worried with this answer.

The question that you ask is a urological question and best answered by a urologist, who is a surgeon. I am a nephrologist and do not have expertise in this area.  I suggest you continue to consult with the urologist. … Continue reading

I have a friend with severe pain in her back, left side. A CT scan showed a 2 cm cyst. She had an ultrasound and they diagnosed it as Indeterminant left renal lesion. She has had pain off an on for a few years. 2 years ago, this cyst was 1 mm. Her pain is very real and severe. At this time, they do not intend to do anything. Is there any other reason she would have this pain? She does have blood in her urine but according to the doctors, no infection. I am very worried about her and think there should be a next step.

A simple cyst on a kidney does not ordinarily cause pain.  I suggest that you consult with a urologist about further studies to be done on the lesion that has been identified on the left kidney.  I am a nephrologist … Continue reading

My Father report shows “Right kidney shows 2-3 small subcentimeter cortical cysts. Left kidney shows a cortical cyst 1.8 cm in size in the lower pole”. Please let me know is it serious? What could be the possible treatment? His age is 65 and he is diabetic and blood pressure.

Cysts of the kidney are almost always benign.  About 4 out of 10 people will develop simple cysts of the kidney as they age.  I would make sure that the radiologist has determined these cysts to be simple cysts (as … Continue reading

Hello, I recently had an Renal ultrasound scan and I see from a copy of the report I received that I have a thin walled simple cyst on my left kidney arising from the upper pole. What is alarming me is the size of it, it is shown as 80mm x 74.6mm x 84.7mm, this seems very big, unless they have typed it wrong. Your opinion would be appreciated.

If the report calls this a simple cyst, then this is a benign cysts.  About 40% of people develop a simple cyst in their kidney as they age.  The size is not particularly unusual.  If you confirm that this is … Continue reading

Back in 2003, I had a CAT scan at Vanderbilt. I was told I had a complex cyst on my right kidney. Since then I never thought about it. I now live in northernmost California. I was looking at my medical records and discovered that since about a year ago my GFR has been 54 and creatinine over 109. The reports said my kidney should last about 2 years. I don’t know what to do. Maybe I need to see a Nephrologist? Can you enlighten me?

I would suggest that you first consult with your primary care physician (PCP) and have a repeat scan to follow up the previous complex cyst.  If the scan can be compared with your previous scan, this may be re-assuring that … Continue reading
