hi,
Any person who develops a renal stone has 50% risk of forming stone in the next 10yrs. Your mother is more prone for stone formation because of
gout. In this condition she will have high blood level of uric acid which is excreted in the urine in high concentration. This leads to recurrent stone formation. If you have the stone with you, get it analysed for composition of stone. Few tips for preventing the stones are
1. Drink adequate water atleast 2-3ltr per day
2. low salt diet
3. She can take urinary alkalising agents like
potassium citrate after consulting her doctor
4. Regular
ultrasound of abdomen to detect stone formation at its earliest stage.
5. Regular followup with your
urologist.
