<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi. doctor , I have a stone in my kidney about 12 mm size and i showed to one urologist he said he will check through laser and destroy it. I AM afraid i told him to give medications instead of surgery . He gave me medicines like MagAsorb2 tablets twice daily with No-URIC1 tablets 2 times daily. My advice is that do it really help with this medications. I have heard of systonehimalaya do this will help easily with enough water to pass by. Pleasem, advice... THANKYOU very Much  <response>: Hi, many thanks for the query! In our body, each kidney is connected to urinary bladder BYA separate narrow tube called ureter. A stone in kidney has to pass through this narrow ureter to reach bladder from there through another narrow tube called urethra, it comes out. Your stone size is 12 mm, but diameter of ureter is smaller enough not to allow this stone pass out. So, some day it will be stuck in the ureter, this will block the urine outflow urine will start accumulating in ureter just behind the stone obstruction further will accumulate in kidney causing back pressure changes in the form of HY Chat Doctor.
