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

I am a 75 yr.old male and through Cat Scan and MRI was diagnosed with Cortical renal cysts within the right kidney. Largest dominant cyst upper pole measures 7.2 cm. with simple appearance. No enhancing renal masses. There is no evidence of renal calculi or obstruction secondary to a renal calculus. In August 2016 I had a right renal cyst aspiration with Cone Beam CT. Though two different Urologists suggested to me not to have this procedure, I was feeling pressure from the cyst and feeling some pain so I decided to have the procedure done. FINDINGS from the Aspiration: Anechoic simple right renal pole cyst. Cone beam CT demonstrates no liver obstructing the access path. Successful aspiration of 250cc of simple yellow fluid. Follow up: Ultrasound 3-6 months for recurrence of cyst. If a recurrence, scierosis will be performed. Dr. Spry, your thoughts and do you agree with follow-up if needed? All tests results (fungal stain, fungus culture, glomerular filtration rate estimated, auto.diff., basic metabolic panel, HEME profile within normal limits. Results of all analyses is one Doctor would not treat with antibiotics. Should I have scierosis if needed? Would this cause pain on my right lower side? Your opinion is most appreciated.

Simple cysts, despite being very large, do not cause pain and should not be treated.  Simple cysts are benign and do not require intervention. For more information on Simple cysts click here:

I’m considering becoming a kidney donor. My personal family physician ordered a CT scan. The CT scan report reveals both kidneys without hydronephrosis. A single dominant mildly complicated cystic lesion with at least one septation is seen within the central portion of the right kidney measuring 3.6 X 2.7 cm. No significant retroperitoneal or mesenteric adenopathy. Impression: Dominant mildly complicated-septated midpole right renal cyst. No cyst seen within the left kidney. Is there a possibility that I could be a kidney donor candidate?

The nature of the complex cyst in your right kidney would have to be determined.  You would not be a candidate to donate a kidney until the nature of this cyst is determined.  I suggest consultation with a urologist about … Continue reading
