<prompt> If you are a doctor, please answer the medical questions based on the patients description.I did a renal doppler test and the result shows the following:1 Both kidneys show increased cortical echogenicity, effacement of cortico-medullary differentiation cortical scarring.2 There is evidence of a left renal mid polar unilocular anechoic cortical cyst3 There is bilateral fullness pelvi calyceal system.How bad is the news and what does it mean in laymans terms?  <response>: Hello and welcome to Chat Doctor. As an Urologist, I can fully understand your concern. What was the reason for doing a renal Doppler scan. Is the creatinine high.1. Your kidney Doppler scan report shows, kidney function may be less than normal. Also, kidneys are affected by recurrent urinary infections.2. Your left kidney shows a single, fluid filled cyst in the central area, which needs to be analyzed further, with a CT scanCENT, or MRU scan.3. Mild collection of urine is present just outside the kidney. You can send me the blood, urine and scan reports for an accurate answer. Send it as a direct question to me. Chat Doctor. Manga.
