Supine vs. Prone Mini-Percutaneous Nephrolithotomy in Children

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective randomized trial compares supine and prone mini-percutaneous nephrolithotomy (Mini-PCNL) in pediatric patients under 15 with a single renal stone 10–30 mm. The study evaluates safety, stone-free rates, total operative time, and complication rates between the two positions. Eligible children undergo standardized imaging to confirm stone size and location, and outcomes are analyzed to determine if the supine approach offers practical or clinical advantages. The trial is sponsored by Fayoum University Hospital with a focus on improving pediatric stone management.
