Abstract

flexible nephroscope. The technique requires pressure irrigation to 300mmHg and an Amplatz sheath to allow free egress of the fragments. J-wire is particularly useful for calyces that are difficult to reach with the rigid nephroscope and allows for quick and atraumatic removal of small fragments. J-wire also allows relocation of stone fragments to a position that can be easily reached with a rigid nephroscope and lithotriptor. CONCLUSIONS: Techniques demonstrated in this video can aid in improving PCNL stone clearance.
