Flank-free modified supine vs. prone position for pediatric nephrolithotripsy: an updated systematic review and meta-analysis.

Introduction: Percutaneous nephrolithotomy (PCNL) is widely performed as the preferred treatment for kidney stones larger than 20 mm in pediatric patients, with current research focusing on comparing outcomes between prone and supine positions to determine optimal procedural positioning. Therefore, the aim of this study is to compare the efficacy of prone versus supine positioning in pediatric PCNL, providing clarity on this critical aspect of the procedure to guide clinical decision-making.

Methods: We conducted a systematic review in PubMed, Embase, Scopus, Cochrane, Web of Science and Google Scholar.

Comparing outcomes of single-use vs reusable ureteroscopes: a systematic review and meta analysis.

Flexible ureterolithotripsy is a frequent urological procedure, usually used to remove stones from the kidney and upper ureter. Reusable uretero-scopes were the standard tool for that procedure, but recent concerns related to sterility and maintenance and repair costs created the opportunity to develop new technologies. In 2016, the first single-use digital flexible ureteroscope was introduced.

Renoduodenal fistula after renal tumor ablation with radiofrequency.

Purpose: To report a renoduodenal fistula after renal tumor ablation with radiofrequency (RFA).

Methods: A 1-inch right anterior renal cell carcinoma was subjected to percutaneous RFA under sedation. We used a 14-gauge probe guided by ultrasonographic images in real time.
