Article Abstract
Introduction And Hypothesis: We present a video demonstrating technical considerations and tips for cystoscopic placement of external, lighted, and internal ureteral stents.
Methods: Cystoscopic ureteral stent placement is useful in cases where difficult pelvic periureter dissection is expected or encountered. In this video, we review cystoscopy basics, our approach to various types of retrograde stent placement, and performing retrograde pyelograms. Traditional external ureteral stent and lighted stent placement for prophylactic purposes are discussed, with attention to understanding stent markings, appropriate resistance, and steps for externalization. Internal, double-J ureteral stent placement with the use of fluoroscopy is initiated with placement of a guidewire. An open-ended ureteral catheter is advanced over the wire in the pelvic portion of the ureter, and a retrograde pyelogram is performed. The wire is reintroduced and the stent advanced to the renal pelvis under fluoroscopy. The proximal curl is confirmed to be in the appropriate position with fluoroscopy. The string attached to the stent is then cut and removed, the guidewire is removed, and the stent is deployed with the distal curl in the bladder.
Conclusions: This video reviews key steps for cystoscopic ureteral stent placement in a prophylactic setting, cases of challenging anatomy, or ureteral injury.

Magnetic resonance angiography in diagnostic long-term follow-up of primary patency of the MOTIV drug-eluting bioresorbable vascular scaffold in the region below the knee: 5 years of experience.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.

Background: Rising antimicrobial resistance (AMR) is an acute public health emergency impeding the clinical efficacy of surgical interventions. Biliary stent placement is one of the routine surgical procedures that rarely lead to infections that are empirically managed by broad-spectrum β-lactams and fluoroquinolones. Critical priority pathogens, such as carbapenem-resistant Escherichia coli challenge treatment outcomes and infection prevention.

Purpose: To report a case series on using a novel semi-branch feature in custom-made stent-grafts in the endovascular treatment of complex aortic aneurysms and summarize the contemporary usage of this technology.
Case Series: Four patients underwent endovascular aortic aneurysm repair (EVAR) with a custom-made semi-branch stent-graft (Semi-Branch Endovascular Aortic Aneurysm Repair [SBEVAR]). Two male patients, 75- and 76-year-old, were treated due to failed EVAR with late-type Ia endoleak, and the other two, 80- and 55-year-old male patients, due to a juxta-renal aortic abdominal aneurysm (JRAAA).
