Comparing kidney stone surgery positions
Modified Supine vs Prone Position Percutaneous Nephrolithotripsy (PNL )in Management of Complex Renal Stones, A Randomized Comparative Study
Assiut University · NCT05379894
This study is testing whether a new way of positioning patients during kidney stone surgery can make the procedure safer and more comfortable compared to the traditional position.

What this trial studies
This observational study compares the efficacy and safety of percutaneous nephrolithotomy (PCNL) performed in the prone position versus a modified supine position for patients with complex renal stones. The study aims to evaluate the advantages of the modified supine position, which may offer better comfort and reduced impact on respiratory function compared to the traditional prone position. By analyzing outcomes from both positions, the research seeks to determine the optimal approach for managing complex kidney stones. Participants will be selected based on specific criteria related to the complexity and location of their kidney stones.
Who should consider this trial
Good fit: Ideal candidates include adults with complex renal stones who meet specific anatomical criteria for PCNL.
Not a fit: Patients with simple kidney stones or those in the pediatric age group may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical outcomes and patient comfort during kidney stone procedures.
How similar studies have performed: Previous studies have shown varying success with different surgical positions in kidney stone management, but this specific comparison is less commonly explored.
