What this trial studies

This prospective randomized study aims to compare the efficacy and safety of endoscopic combined intrarenal surgery and percutaneous nephrolithotomy (PCNL) in treating staghorn stones. The study will evaluate the stone-free rate as a measure of efficacy, using DMSA scans before and after the procedures. Additionally, it will assess the safety of each surgical method by monitoring intra- and post-operative complications. The goal is to determine which approach is more effective and safer for patients with this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 with renal staghorn stones confirmed by imaging.

Not a fit: Patients with renal insufficiency, active urinary tract infections, or other specified exclusions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective and safer treatment option for staghorn calculi.

How similar studies have performed: Previous studies have shown varying success rates for similar surgical approaches, but this specific comparison is novel.
