Hi, many thanks for the query!
To decide whether operation is needed or not, you need to do certain investigations- USG (KUB), X-ray KUB, Sr. uric acid, Sr. creatinine
, Urine (routine & microscopy), IVP (if needed as per reports of other investigations).
You should take stone conservative treatment including Diuretics, Anti-spasmodics, urine alkalinizing agents, uric acid synthesis inhibitors (if raised) like allopurinol
as per your doctor's opinion.
Drink plenty of oral fluids so that 3 litres of urine is voided in 24 hours.
Wish you a good health. Take care.
