Hi,
Stone disease by nature has a potential for recurrence.
I feel you are doing correctly by consuming good amount of water,KCit.
But in place of Lasilactone ,take
Aldactone 25mg once daily.
You may continue
Homeopathy treatment.
Increase water intake to 3.5-4litres daily.
Start Tab Cystone 2 tabs twice daily and Cap Urimax 0.4mg once daily.
This treatment will be very effective.
In view of recurrence, also get urine-24 hours uric acid,
oxalate,phosphate,calcium,proteins,
creatinine estimation, Blood-iPTH, 25(OH)D3 estimation,kft done.You can convey the reports once done
