Effectiveness and safety of retrograde intrarenal surgery (RIRS) vs. percutaneous nephrolithotomy (PCNL) in the treatment of isolated kidney stones.

Objective: To compare the effectiveness and safety of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) in the treatment of isolated kidney stones.

Methods: A retrospective analysis was performed on 99 patients with isolated kidney stones treated in our hospital. Patients were divided into a flexible cystoscope group (FCG, n=48, receiving RIRS) and a nephoscopy group (NG, n=51, receiving PCNL) according to the operation methods.
