Modified amplatz sheath with suction versus standard sheath in percutaneous nephrolithotomy for treating large renal stones > 2 cm: a prospective randomized trial

1

Percutaneous nephrolithotomy (PCNL) is the gold standard for treating large renal stones over 2 cm due to its efficacy and low morbidity.
2

This study compares a modified Amplatz sheath with a standard sheath in PCNL to evaluate improvements in operative time and postoperative outcomes.
3

240 patients with renal stones larger than 2 cm were randomized into two groups for PCNL using either the standard or modified Amplatz sheath.
4

The modified sheath features a suction channel that enhances visibility and facilitates efficient stone clearance during the procedure.
5

Primary outcomes included stone-free rates, operative time, complications, and length of hospital stay, analyzed using appropriate statistical methods.
