We assessed our initial experience with tubeless percutaneous nephrolithotomy (PCNL). Between February 2011 and December 2013, we performed 155 tubeless PCNL and 54 standard PCNL in which nephrostomy tubes were used postoperatively.

... and stone-free rates were compared between the two groups. The mean hospital stay after tubeless PCNL was shorter (5.1 days) than that after standard PCNL (6.8 days, P<0.05).

Tubeless PCNL is a safe and effective procedure, and hospital stay is shorter with tubeless PCNL than with standard PCNL.
