[|Human|] I have 4.9mm stone in interpolar right kidney. no hydronephrosisWhat are my treatment options? I had a stone episode 14 months ago and a 6mm stone was removed using ureteroscopy and stent last year from left kidney distal ureter.  The stone is a calcium oxalate stone.
[|AI|]  Hi, Thanks for writing in to us. As long the stone is in the kidney there is no problem as it is a small stone. It is possible that the stone might enter the ureter (tube connecting kidney and urinary bladder) and when in the lower part of ureter and at that time it might cause obstruction to flow of urine. You might have pain at this time which will disappear once the stone reaches the urinary bladder. When this happens you might experience severe sharp pain for few days and require painkillers for some time. Please continue Chat Doctor. Stenting and ureteroscopy is not required unless the stone grows in size and causes obstruction to flow of urine.
