Hello Thanks for query .You have been detected to have a stone of a size of 7.2 mm in your Right kidney and your family physician has prescribed antibiotics .pin killers and Alkaston B6 syrup (Urine Alkaliser). Let me state that there is no medicine an any faculty of medical fraternity that can dissolve or break the urinary stone . All the medicines that are being prescribed are antibiotics to prevent infection and painkillers , A stone of a size of 7 mm can be expected to pass out spontaneously through urine .Active intervention is needed only when it gets impacted in ureter and causes back pressure changes in kidney and proximal ureter giving rise to symptoms like severe pain in back ,vomiting and fever . You need to follow following regime 1) Drink more water to produce more urine so that stone will get flushes out at ease . 2) Take Tomsulosin once daily .This helps to dilate the ureter and therby to pass the stone down . 3) Pain killers With this most of the stones below the size of 8 mm pass out in urine . Dr.Patil.
