Abstract

Objectives: The aim of this research is to evaluate the efficacy and safety of mini percutaneous nephrolithotomy in the treatment of kidney stones. Patients and methods: A retrospective combine prospective-descrivetive study of 92 patients suffering from kidney stones treated by mini-PCNL at Medical Center Cam Khe-Phu Tho from 1/2022 to 6/2023. The technique is performed under ultrasound, using a 16 Fr nephroscope of Karl-Storz. Holmium laser is used to disintegrate the stones. Evaluate the stones free rate and complications postoperatively. Results: 92 patient 60 males (65,2%) and 32 females (34,8%) with the mean age of 52±11,76 years (range from 19 to 70 year old). 73,9% have one stones, 26,1% have more two stones. The grade of hydronephrosis on preoperative MSCT: No hydonephrosis and grade I (21,7% and 42,7%), grade II (28,3 %), and grade III (7,6 %). Average length stone size 25,7±5,9 mm, average width stone size 16,3±2,5 mm. Operative time 71,86±15,09minutes (45 - 80). Postoperative stone free rate 79,3%, stone free rate at 1 month postoperative follow-up 90,2 %. 80 patient follow-up 20 ± 6 tháng. There are 2 patient have piece stone fall ureter need retrograde ureteral lithotripsy. 1 patient have stenosis ureter need cut and retrograde ureteral stenting with double J. No case required blood transfusion, renal atrophy, kidney failure, sepsis. Time postoperative hospital stay 7,67±3,21 days (4-10). Conclusions: Mini-PCNL was successfully performed at Cam Khe-Phu Tho Medical Center  with encouraged initial outcomes. High stone free rate, shorter hospital stay, no major complication. Further research should be conducted in order to full-fil access the effectiveness and safety of mini-PCNL in patients with larger kidney stone.
