NCT ID NCT07295860
First seen Jan 03, 2026 · Last updated Jun 22, 2026 · Updated 40 times
Summary
This study will compare two advanced, suction-assisted surgeries for removing kidney stones that are 2-3 cm in size. About 280 adults across nine hospitals in Egypt will be randomly assigned to either FANS-based flexible ureteroscopy or suction mini-PCNL. The main goal is to see which method clears more stones completely after one month, while also tracking pain, complications, 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
Procedure: FANS-based flexible ureteroscopy or suction-assisted mini-percutaneous nephrolithotomy
What this could lead to
If this trial succeeds, it could help doctors choose the best, safest surgery for medium-sized kidney stones, leading to fewer complications and faster recovery.
What could go wrong
This is a head-to-head comparison, not a test of a new drug or cure. The results may not apply to all stone types or patients, and both procedures carry standard surgical risks like infection or bleeding.
