Summary

This study looks at how anxious adults feel before undergoing one of two common surgeries for kidney stones: retrograde intrarenal surgery (RIRS) or percutaneous nephrolithotomy (PCNL). Researchers will measure anxiety using standard questionnaires and also record patient and stone details to see what factors are linked to higher worry. The goal is to better understand preoperative anxiety in these patients, which could help improve their experience.

What this could mean

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

What this could lead to
If this study succeeds, it could help doctors identify which patients having kidney stone surgery are most anxious, leading to better support and care before procedures.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may not apply to all patients, and anxiety levels can be influenced by many unmeasured factors.
