My query - Why am I susceptible to stone formation so much. And what can be done to prevent it. Details are below: I have had a surgery for calculus removal in 2016, right ureter PCNL (size - 14 mm). Type - Calcium oxalate Family history - Grand mother had it, Elder aunt had it Other a Occurences - in jan 2019 passed an approx. 3mm sized stone while urinating in office November 2019 - diagnosed with Fatty lever grade 3 with 1 stone in left kidney Now the stone is causing pain. If it helps - I was diagnosed with osteomalacia in 2015 for which 1 injection of 6 lakh units was prescribed But the Medicine doctor made me go for 6 of those injections ( cal level in body went from 8 to 63 )
