<s>[INST] Hi I have a poor left kidney function. It works only 10%. It is small in size measuring about 5cm. A replantation ureter was done 23 years ago because there was urine reflux to the both kidneys. Regarding the right kidney, it works well and measures about 9 cm. however, a uric acid stone was discovered in it. It measures about 1cm.The uric acid in the blood is high. It is 9.5ml. I started taking the uralyte four days ago and it seems to me that the medice is not working yet. My question is how long does it take for the medice to start dissolving the stone? Many thanks to you Doctor. [/INST] HelloThanks for query.You have poorly functioning left kidney and normal Rt kidney with Uric acid stone of a size of one cm.and have been advised to take Uralyte to reduce serum uric acid levels .It takes month or even more to dissolve the uric acid stone in kidney ..You should have patience and continue taking it  Ensure to drink more water and take urine alkalizer along with Uralyte..Dr.Patil. </s>
