Hi, many thanks for the query!
As you are recurrent stoneformer, do - Metabolic workup of 24 hrs
urine sample, Sr. PTH, Sr. Calcium, Sr. Uric acid.
B/L obstruction to urine outflow due to stones may compromise renal function, do- RFT, USG KUB.Dialysis
is needed when renal function is severely compromised, in your case, your Sr. creatinine
(more than say 7.5 to 8) will decide need for dialysis.
You haven't mentioned exact size & site of your stones.Lithotripsy
failure is expected as Ca-oxalate
stones are very hard to break by ESWL, need to be removed by scopy/open procedure.
Wish you a good health.
