Purpose: To evaluate association between postoperative serum procalcitonin (PCT) levels and infectious complications following mini-percutaneous nephrolithotomy (mini-PCNL), and to identify predictors of elevated PCT.
Methods: We retrospectively analyzed 496 adult patients who underwent mini-PCNL for kidney stones (February 2020-March 2025). Patients were stratified into four groups based on postoperative fever occurrence and PCT levels (≤ 2.

Article Synopsis
- The study aimed to develop a machine-learning model to predict the risk of sepsis following retrograde intrarenal surgery (RIRS) for kidney stones, including data from 1,552 patients across 16 centers.* -
- Inclusion criteria for patients were specified, and certain conditions like concomitant ureteral stones were excluded, with antibiotic treatments used where applicable.* -
- The Random Forest algorithm outperformed other machine-learning models, achieving high precision, recall, and accuracy, and a web-based version of the predictive tool is available for use in clinical settings.*
The Significance of Stone Culture in the Incidence of Sepsis: Results from a Prospective, Multicenter Study on Infections Post Flexible UreteroreNescopy (I-FUN) and Laser Lithotripsy for Renal Stones.

Sepsis is the most serious complication of flexible ureteroscopy (F-URS) and laser lithotripsy. We assessed the influence of positive stone culture (SC) on major infectious complications (sepsis, septic shock). This prospective study enrolled adult patients deemed suitable for F-URS and laser lithotripsy from nine centers (January 2022-August 2023).
