I was recently diagnosed with Bosniak 2 complicated cysts with 2 simple cysts on left kidney. During ultrasound, left kidney size measured 7.9cm, right was 8.4. I’m 5’2″ weigh 130. 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. My question, is the kidney size normal? IF not, what are some possible diagnoses? I do have an upcoming appt with urologist.

I am not an expert in kidney cysts.  This is usually the expertise of a urologist. I am a nephrologist.  The size of your kidneys should be in proportion to your body size.  I am unable to comment on your … Continue reading

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

Here is a little history: I’m 25 years old and was diagnosed with CKD when I was 17 years old. I have cysts on my kidneys and currently my kidney function is 23%. My electrolytes are chronically low, mostly potassium and bicarbonates. Sometimes my phosphorous and magnesium are low as well. All of these can drop below normal ranges in spite of me taking supplements everyday 2-3 times a day. I was originally diagnosed with nephronophthisis but more recently my nephrologists have said that may not be the correct diagnosis. I have been to multiple hospitals (Barnes, Mayo, and Northwestern) and it seems like every time I go I have the same initial reaction: We need to figure out how I’m losing electrolytes, verify the diagnosis, etc… But when the results come back from multiple tests the doctors don’t know what to tell me and I’m back to square one. My questions to you are: should I be concerned that there isn’t a concrete diagnosis for my disease? Should I keep pushing to find a diagnosis or will it matter in the long run since the treatment is going to be a transplant regardless?

Nephronopthisis is a very rare autosomal recessive genetic disorder of the kidney.  I do not have a great deal of experience with this disease.  Experts at the institutions that you mention should be able to provide a specific diagnosis but … Continue reading

Last year they found a complex renal cyst size 3.4cm. Had CT scan and they said it was okay. Now ultrasound shows it has grown to 4.2cm. Going for CT scan next week. What am I facing? What is the likelihood I have to have surgery?

The problem that you describe is a urological problem.  Urologists make decisions about when to perform surgery on a cyst in the kidney.  If this is a simple cyst, then no surgery should be anticipated.  If this is a more … Continue reading
