Abstract

Objective: To describe the clinical, paraclinical characteristics of patients with infectious complications after mini-PCNL.

Patients and methods: The descriptive study was conducted on 29 patients who developed infectious complications after mini-PCNL at the Department of Urology, Thai Nguyen National Hospital, from January 2024 to December 2025.

Results: The mean patient age was 58,6 years. Diabetes mellitus was present in 17.2% of patients, and 41.3% had positive urine cultures. The mean stone size was 43.8 mm. According to the Guy’s Stone Score, grade II was the most common (65.5%), followed by grade IV (17.2%) and grade III (13.8%). The median number of stones was 2. The median duration of preoperative antibiotic use was 3 days. Among infectious complications, SIRS was the most frequent (58.6%), followed by postoperative fever (31.0%), urinary tract infection (3.4%), and septic shock (6.9%); no deaths was recorded. Infectious complications usually occurred early after surgery with a median onset of 1 day. Fever were the most common clinical manifestation (86.2%) and elevated procalcitonin levels were observed in all tested cases. The median postoperative treatment duration was 7 days.

Conclusion: Infectious complications following mini-PCNL were generally mild, with SIRS being the most common presentations. These complications typically occurred with the first postoperative day and were characterized by fever and elevated procalcitonin levels. Advanced age, diabetes, positive preoperative urine culture, large or complex stones may be potential risk factors for postoperative infectious complications.
