Summary

This study compared two ways of doing kidney stone surgery (PCNL). In the standard method, a tube is left in the kidney to drain urine, which can cause pain. In the tubeless method, no tube is placed. Researchers measured pain and painkiller use in 60 adults after surgery. The goal was to see if the tubeless approach leads to less pain and faster recovery.
