Abstract :The new minimally invasive techniques that have entered the therapeutic arsenal have created a veritable revolution in the management of urinary lithiasis: extracorporeal lithotripsy (ECL), percutaneous nephrolithotomy (PCN) and flexible ureteroscopy (FUS). The main challenge is to achieve complete removal of the stone without residual fragments, with less risk of complications.

In this work, we focus on inferior calcific calculi, given the diversity of the therapeutic arsenal available and, above all, the ever-present dilemma of inferior calcific geometry and its implication in the choice of treatment. Summary:The new minimally invasive techniques that have integrated the therapeutic arsenal have created a real revolution in the management of urolithiasis: extracorporeal lithotritia (ESWL), percutaneous nephrolithotomy (PCNL) and flexible ureteroscopy (FURS).

The main challenge and to achieve complete removal of the lithiasis without residual fragments with less risk of complications. In this work, we are interested in lower calicial lithiasis because of the diversity of the therapeutic arsenal.
