Hi, many thanks for the query!
You need to do- Sr. creat., Sr. uric acid, X-ray KUB, Urine (R&M),
IVU (Intra-Venous Urography).
If stone can be seen causing obstruction in lower ureter
, surgical removal should be done, ureteroscopic removal (URS) is preferred these days.
Take antispasmodics, pain killers, diuretics, tamsulosin
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.
