Abstract
We aimed to explore the applicability and safety of micro-percutaneous nephrolithotomy (micro-perc) in the treatment of children with kidney stones in the Galdakao-modified supine Valdivia (GMSV) position under the guidance of whole-course ultrasound. Patients were aged < 18years in the GMSV position who underwent micro-perc for kidney stones under ultrasound guidance between August 2020 and May 2022 at our institution were reviewed retrospectively. A total of 23 patients, 15 males and 8 females, received micro-perc. The average stone size was 1.6cm (range 1.1-2.0cm). Among them, 12 patients had left kidney stones, 10 patients had right kidney stones, and 1 patient had bilateral kidney stones. The mean operative time was 55.3min (range 35-86min). The mean hospital stay was 2.9days (range 2-4days). The mean hemoglobin decrease was 1.7g/L (range 0.9-3.2g/L). A total of 17 patients had complete stone clearance at 48h postoperatively. A total of 22 patients had complete stone clearance at 2weeks postoperatively. Our results demonstrate that micro-perc under ultrasound guidance is a safe and effective method for the treatment of children with kidney stones in the GMSV position. Further research is warranted to confirm these results.
