I have renal calculus of 4.5 mm in lower calyx of my right kidney. I never felt any severe pain due to this, only very mild pain sometimes. I'm in a profession in which getting medical clearance certificate is vital. The authorities conducting medical for this profession have asked me to get this stone completely removed to provide medical fitness certificate. I have tried my level best - done 3 sessions of ESWL, taken medicines prescribed by various doctors. But still the stone did not get remove. Then I decided to go for PCN or arthroscopic surgery to get this removed, but none of the doctor that I met are prescribing such surgeries on such a small stone. Now I am left with 7-10 days to report back to medical authorities and I have no idea what to do to remove this stone in just 7-10 days. Please guide me. I will be very thankful to you for your help as my job is at stake.
