Thanks for your query.

You have one cortical cyst in left kidney. Usually such simple cysts are detected in sonography and are filled with fluid.

These are commonly benign (Non cancerous). It needs only monitoring and no intervention is required. In case of larger cysts with septa and solid component, they need to be investigated and rule out malignancy.

Your kidney cyst is 4.5 cm which is slightly big we need to know the nature of the cyst. If you can upload the report of sonography, I can guide you better on that.

Hope this information helps.
Awaiting your input to clarify better.

Best regards.

Thanks for follow up,
I have seen your report of Sonography; it is showing only one cortical cyst of 4.5 cm,
All other findings are normal.
Your renal function and urine analysis are normal as you said.
This type of cyst is benign (Non cancerous) and just need follow up and no intervention is required.
Please do not worry at all.
Although follow up may be after 6 month may be done.
Hope I have answered you query, if nothing is there please accept my answer.
If you have any further query, I will be happy to help you.
Best Regards.

As I told you in my answer most simple cyst are benign (non Cancerous). But a follow up is needed to make sure we do not miss out changes in size or nature of cyst - although it is rare.

Hope this relaxes you and if you do not have any other query please accept the answer and close this discussion.
