EVALUATE THE RESULTS OF KIDNEY STONE TREATMENT USING MINI-PERCUTANEOUS NEPHROLITHOTOMY IN FLANK POSITION

Tóm tắt

Background: Minimally invasive approaches for kidney stone management, notably minipercutaneous nephrolithotomy (mini-PCNL), are increasingly favored over traditional open surgical techniques. The prone position is predominantly utilized during mini-PCNL procedures; however, it poses challenges in patients with respiratory limitations or anesthetic concerns. Consequently, the flank position, frequently adopted by urologists due to familiarity and anesthetic convenience, has emerged as an alternative approach. Objective: This study aims to evaluate the clinical outcomes of mini-percutaneous nephrolithotomy performed in the flank position for kidney stone treatment at Can Tho University of Medicine and Pharmacy Hospital. Materials and Methods: This investigation was conducted using a descriptive cross-sectional design. All patients diagnosed with kidney calculi measuring ≥ 20 mm undergoing mini-PCNL at Can Tho University of Medicine and Pharmacy Hospital were included. Results: Between November 2022 and March 2024, a total of 60 patients underwent mini-PCNL, comprising 32 males and 28 females, with a mean age of 50.5 years (ranging from 30 to 80 years). The mean stone diameter was recorded as 30.8 mm. All procedures were successfully completed in a 90-degree flank position. Kidney access was achieved through the lower calyx in 55% of cases and via the middle calyx in 45%. The average duration of surgery was 70.4 minutes. No intraoperative complications occurred. Postoperative complications were identified in 4 patients (6.7%). The mean length of hospital stay was 6.5 days. An early postoperative stone-free rate of 78.3% was achieved. Conclusion: Mini-PCNL in the flank position proves to be a safe and effective approach for managing kidney stones, providing a high stone-free rate with minimal complications.
