Summary

This study will compare two minimally invasive surgeries for kidney stones that are 2-3 cm in size. About 280 adults across nine hospitals will be randomly assigned to either FANS-based flexible ureteroscopy or suction-assisted mini-PCNL. The main goal is to see which method removes more stones completely after one month, while also tracking complications, pain, and recovery time.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

surgical procedures (FANS-based flexible ureteroscopy and suction-assisted mini-percutaneous nephrolithotomy)

What this could lead to

If successful, this study could help doctors choose the best surgical method for medium-sized kidney stones, leading to fewer complications and better stone clearance.

What could go wrong

This is a surgical comparison trial, not a new drug or device. Results may not apply to all patients, and both procedures carry standard surgical risks like infection or bleeding.
