    Abstract
  •   Objective   This study aims to evaluate the efficacy and safety of percutaneous nephrolithotripsy assisted by the needle-perc system without artificial hydronephrosis in the treatment of pediatric renal stones.   Methods   A total of 11 pediatric patients with renal stones treated underwent percutaneous nephrolithotripsy using the visualized needle-perc system were enrolled in Shannan People ' s Hospital during August 2021 to October 2022. The cohort included 7 males and 4 females aged 5-16 years, with 4 patients on the right side and 7 patients on the left side. Among them, 5 patients had single renal pelvis stone and 6 patients had multiple calculi. The maximum mean diameter of calculi was (18.46±6.52) mm, with a mean CT value of (835.04±135.74) HU. All of them underwent percutaneous holmium laser lithotripsy under general anesthesia using a visualized needle-perc system, with the target calyx punctured by a 4.5Fr visualized puncture needle under ultrasound guidance. Subsequently, F16 percutaneous renal access was established, and lithotripsy was completed using a 550 μm holmium laser. After the operation, an F12 fistula was maintained in place, following a needle-perc nephrolithotripsy procedure without the need for an indwelling nephrostomy tube. The operation duration, complications, hospital stay, and stone clearance post-surgery were evaluated.   Results   All children were successfully operated, with 3 cases undergoing complete needle-perc nephrolithotripsy and 8 cases using a visualized needle-perc system. The average operation duration was (79.55±10.76) min, postoperative hemoglobin decreased by (10.09±5.25) g/L, and the average postoperative hospitalization period was (5.54±1.07) days. The stone clearance rate was 100% at the 4-week postoperative follow-up. No serious complications such as access loss, postoperative infection, severe bleeding, or injury to the kidney or adjacent organs during and after the surgery.   Conclusion   Needle-perc system assisted percutaneous nephrolithotomy without artificial hydronephrosis is safe and effective in the treatment of pediatric renal stones. It demonstrates a low incidence of surgical complications and can achieve a satisfactory stone removal rate, making it suitable for individualized pediatric renal stone treatment. Furthermore, this technique holds clinical significance in regions with a high incidence of kidney stones among children living on plateau.
