Abstract

Objectives: The study aim was to evaluate the results of mini-percutaneous nephrolithotomy    under ultrasound guidance for treatment of kidney stones at Lang Son Province General Hospital in the period from 2022 to 2024. Materials and Methods: A case series study with longitudinal follow-up, 76 patients have been operated by mini percutaneous nephrolithotomy under ultrasound guidance at Lang Son province General Hospital from June 2022 to July 2024. Results: The  average  age  was  50.68 ± 11.16  years (29 – 73). Mean stone size was 3 ± 1.01 mm (1.7 – 7.1), in which stone size 15 – 30mm: 35 cases (46.1%), 31 – 40mm: 27 cases (35.5%) and > 40mm: 14 cases (18.4%). Hydronephrosis classification: Grade 0 (no dilation): 4/76 cases (5.3%), grade I: 39/76 cases (51.3%), grade II: 23/76 cases (30.3%), grade III: 9/76 cases (11.8%).
