Objective: To report one case of proximal migration of ureteral stent. To perform a bibliographic review about other cases and management to avoid this complication.
Methods/results: 48-year-old woman who presents right obstructive uropathy after gynecologic surgery. After the introduction of the right ureteral stent we observed a proximal stent migration. We put on a right nephrostomy tube and antergrade ureteral stent.
Conclusions: The right stent length and proper location of the distal tip are important factors to avoid this complication.

: The objective of the current research is to assess the benefits that come with antegrade ureteral stenting coupled with imaging techniques in children and also provide a new classification based on the ureter's morphological elements. : Between 2011 and 2024, 107 antegrade stent placement procedures performed in 71 pediatric patients aged 0-12 years who could not undergo retrograde double-J stent placement were retrospectively analyzed. According to the morphologic structure of the ureter, four categories were classified as normal, straight/slightly angled, S-shaped, and spiral-shaped.

This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO/AgNPs) on the properties of biodegradable ternary blends composed of poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), and polycaprolactone (PCL) by examining the morphology, thermal stability, crystallinity index, and cell viability of these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs and SiO exhibited comparable sizes, whereas ZnO was significantly larger, which influences their release profiles and interactions with the blends. The addition of antimicrobials influences the rheology of the blends, acting as compatibilizers by reducing the intermolecular forces between biopolymers.

Objective: This study aims to evaluate the impact of preoperative stenting on surgical outcomes and complications in patients with bilateral ureteric stones, specifically assessing its role in reducing the need for subsequent interventions.
Methods: A retrospective analysis was conducted at a tertiary center over eight years, involving 82 patients with bilateral ureteric stones. Patients were divided into two groups: Group 1 (no preoperative stenting) and Group 2 (preoperative stenting).

Objectives: We aimed to assess the stone free rate of flexible ureteroscopy and laser lithotripsy (FURL) in upper urinary tract stones (UUTS) >20 mm and the risk of complications from ureteral access sheath (UAS) usage.
Methods: This is a prospective randomized clinical trial that included patients with UUTS larger than 20 mm who underwent FURL after randomization into two groups: group A (UAS) and group B (non-UAS). Data were collected for patients' demographics, stone parameters, operative and postoperative complications, and the outcome of FURL regarding stone-free rate (SFR) and perioperative complications, with a 6-month follow-up.

Pelvic kidney is a congenital anomaly characterized by the kidney's failure to ascend to its normal anatomical location during early embryonic development. This anomaly complicates traditional surgical approaches for renal calculi due to the kidney's atypical positioning and associated anatomical challenges. We sought to summarize our experience with robotic-assisted pyelolithotomy (RPPK) for pelvic kidney stones.
