Hi, many thanks for the query!
Well, a 2 mm calculus in interpolar region of kidney
need not be removed surgically, if there is no hydronephrosis/hydroureter.ESWL
would be un-necessary in your case.
You should do- USG KUB, X-ray KUB, RFT, LFT, Urine (R&M).
Take Stone Conservative Treatment including- antispasmodics, pain killers, diuretics, potassium-magnesium citrate
, urine alkalinizing agents with your doctor's opinion.
Drink plenty of water so that at least 2 litres of urine is voided in 24 hrs.
Wish you a good health.
