Giant kidney stone: multi-session percutaneous nephrolithotomy with 12 accesses

摘要

We report a case of a 37-year-old man with a body mass index of 28 kg/m² who presented to our outpatient clinic with intermittent left flank pain. Non-contrast abdominopelvic computed tomography revealed a giant coralliform calculus in the left kidney. This giant kidney stone was successfully treated with 3 sessions of percutaneous nephrolithotomy (PNL) with a total 12 accesses. There was no significant reduction in the split function of the kidney after PNL.
