I am 29 years old. I have recurrent kidney stones problems. Almost every 1-2 month I am getting kidney stones of 3-5 mm. Earlier it was like after every 1-2 years but from last one year I am getting it after every 1-2 months. Pth-26.6, calcium 9.6, uric acid 7.9,urine ph-6, 24 hour urine cal, phosphorus, citrate, uric acid, oxalate was in normal limit. I have consulted number of urologist but nothing has been found. Why it's being happen so repetitively within very less time span. I am not able to find. Drinking 3-4 litre water also. All the rft panel are also wnl.
