Brief Answer:
Renal cortial thinning results from chronic disease.

Detailed Answer:
Hi, I have gone through your question and understand your concerns.

Usually thinning of cortical renal layer results from nephron loss due to chronic renal disease.

When it is only one kidney affected, this happens by increased urine pressure on kidney, usually by obstruction of urine flow ways. ( kidney stones, anatomical individual characteristics, compression on ureters etc.)

If it is stable and blood work tests about kidney function together with normal urinalysis, I think you just need to be followed up periodically.

Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
