Abstract

Objectives: To evaluate the results of mini percutaneous nephrolithotomy (mini-PCNL) for the treatment of kidney stones with stabilized urinary tract infection. Methods: A descriptive study was conducted on 40 patients who underwent surgery at Thai Nguyen National Hospital from January 2024 to March 2025. Results: Mean stone size was 42.1 ± 18.6mm. According to the Guy’s Stone score, grade II accounted for 66.7%, while grades III and IV accounted for 16.7% and 9.5%. Escherichia coli was the most common causative pathogen of urinary tract infections. Multidrug-resistant bacteriuria was identified in 32.5% of patients. The median duration of preoperative antibiotic therapy was 6.5 days. The stone-free rate was 69%. Overall complication rate was 17.5%, including postoperative fever (2.4%), systemic inflammatory response syndrome (7.1%), septic shock (2.4%), and bleeding requiring blood transfusion 4.8%. The median postoperative treatment time was 5 days. Conclusion: Mini percutaneous nephrolithotomy is an effective and relatively safe method for treating kidney stones with controlled urinary tract infections, achieving a rate of 69% and a postoperative complication rate of 17.5%. Preoperatively, a stone-free management of urinary tract infections plays a critical role in reducing the risk of postoperative infectious complications.
