Hallo Thanks for your query.You have stones in your kidney since a long time and you have neglected the same.Please note that you are putting your life at stake by neglecting it.Please get your assessment done by doing following investigations
1) Plain X ray abdomen to locate the stones.
scanning of the abdomen
3) Blood Investigations to asses renal function (Blood Urea and Serum Creatinine
4) Intravenous Pyelography.
After doing all these investigation consult some Urologist
who will decide the mode of treatment depending upon the locaton of stones etc.Please note that now a days all the stones in the urinary system
can be treated by Endoscopy
and no major surgery is required.Since you have a financial problem you can visit any Govt Hospital to get these things done as most of the Govt hospitals have these facilities available at .free of cost.
