About this study

Percutaneous nephrolithotomy (PCNL) is a cornerstone in managing large renal calculi. However, in patients with a history of previous open renal surgery (POS), retroperitoneal scarring, altered anatomy, and vascular complications may influence PCNL outcomes.

The literature remains inconsistent regarding whether POS negatively impacts PCNL success or increases complications. Therefore, this study aims to clarify the comparative safety and efficacy of PCNL in patients with and without prior open renal surgery.
