Kidney stones (renal calculi) are hard deposits of minerals and salts that form inside the kidneys. When stones are too large to pass naturally, surgical intervention is required. At Maiya Hospital, we offer the complete spectrum of minimally invasive kidney stone removal techniques — including ESWL (shockwave lithotripsy), ureteroscopy (URS) with laser lithotripsy, and PCNL (percutaneous nephrolithotomy) for large or complex stones — ensuring the most targeted, effective, and least invasive treatment for every patient.
