Objective: To investigate the clinical efficacy and safety of fluoroscopic guided percutaneous antegrade ureteral stents placement used for treatment of malignant ureteral obstruction.
Methods: Between April 2016 and March 2018, fluoroscopic guided percutaneous ureteral stents was performed in 25 patients, including 7 patients (28%) with bilateral obstruction. The most common cancer diagnoses were cervical cancer (28%), rectal cancer (24%) and colon cancer (16%) among these patients. Clinical data were retrospectively analyzed with respect to the efficacy, safety and outcome of this treatment method.
Results: Percutaneous antegrade placement of ureteral stents was performed in all cases, including 12 ureters that failed in the initial retrograde ureteral stents placement. The median stent patency time for the antegrade ureteral stents were 10.4 (95% CI: 8.3-12.6) months. The primary complications included mild flank pain and discomfort (44%), hematuria (44%), urinary tract infection (8%), bladder irritation symptoms (4%), and arterial bleeding (4%).
Conclusion: Fluoroscopic guided percutaneous ureteral stents placement is a safe, efficient procedure and has a high success rate in patients with malignant ureteral obstruction.

Rationale: Acute myocardial infarction (AMI) is the leading global cause of death from cardiovascular disease, and the mortality rate increases in the presence of comorbidities such as renal abscess. The treatment of AMI combined with renal abscess is challenging, especially in combination with urinary tract obstruction, as percutaneous coronary intervention (PCI) can lead to progression of the renal abscess and deterioration of renal function. Currently, there is no consensus on the treatment of renal abscess in AMI.

: 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).
