To determine the feasibility and safety of percutaneous nephrolithotomy (PCNL) in treating upper urinary calculi under local infiltration anesthesia.A series of 2000 patients with upper urinary calculi underwent PCNL under local infiltration anesthesia. Of the 2000 patients, 536 had upper ureteral calculi, 805 patients had pelvic calculi, and 659 patients had complex renal calculi. Pethidine premedication (75-100 mg) and Phenergan (25 mg) were used half an hour preoperatively. The mean pain scores at 0, 6, 24, and 48 hours postoperatively, the demographic characteristics, and the stones characteristics were evaluated to determine the feasibility. The complications were evaluated to determine the safety, and stone-free rate was evaluated to determine effectivity.The mean American Society of Anesthesiologists score was 1.55 ± 0.54 (range, 1-3). The mean operative time was 48 minutes (range, 20-125). The mean Visual Analogue Scale scores at 0, 6, 24, and 48 hours postoperatively were 3.62, 3.02, 2.27, and 2.09, respectively. The mean hemoglobin drop was 1.06 g/dL (range, 0.2-6.8). Sixty-five patients (3.3%) received transfusions, 10 patients (0.5%) required selective renal angioembolism (Clavien grade II), and 1 patient (0.05%) received chest drainage therapy (Clavien grade II). The total stone-free rate was 85.8%.Local infiltration anesthesia is a well-tolerated alternative anesthesia technique that provides effective intraoperative and postoperative analgesia for PCNL. PCNL performed under local infiltration anesthesia in a selected group of patients is feasible and provides satisfactory clinical outcomes. Comparative studies should be performed to classify efficacy, safety, tract quantity, dilation method, and the best candidates.
