Abstract

Background: Percutaneous nephrolithotomy (PCNL) is a minimally invasive and effective treatment for complex renal stones, helping reduce complications and preserve renal parenchyma. Patients and Methods: This descriptive case series included 25 patients with complex renal stones treated by mini-PCNL at Ninh Thuan General Hospital from November 2021 to October 2022. All procedures were performed under ultrasound guidance, using Holmium laser lithotripsy, followed by antegrade JJ stent placement and percutaneous nephrostomy drainage at the end of surgery. Results: The mean stone size was 3.11 ± 2.41 cm, and the mean operative time was 58.4 ± 27.8 minutes. The early postoperative stone-free rate was 82.4%, increasing to 88.7% after one month. Postoperative complications occurred in 16% of cases, mainly transient fever and perirenal fluid collection; no severe bleeding was reported. The mean hospital stay was 5.6 ± 2.3 days. Conclusions: Ultrasound-guided mini-PCNL is a safe and effective technique for treating complex renal stones, achieving a high stone-free rate with minimal complications. This procedure can be feasibly implemented at provincial-level hospitals equipped with appropriate instruments and trained urologists.
