Article Abstract
Objective: The specific anatomic characteristics of the right internal spermatic vein (ISV) are pivotal factors in embolism failure. However, the inherent angles and configurations of the right ISV remain incompletely explored. This study aimed to address this gap by conducting a thorough investigation into the specific anatomic characteristics of the right ISV using imaging analysis in southwest China.
Methods: This retrospective study analyzed the imaging data of 1000 male patients who underwent multidetector spiral computed tomography (MCT). Anatomic characteristics of the right ISV, including position, type, distance, and angle, were also evaluated.
Results: The most common anatomic type (87.8%) of the right ISV was direct drainage into the inferior vena cava, with 90% of the angles below 25.7°. There were 22 cases (2.2%) with parallel right spermatic veins. In the axial plane, the right ISV (86.4%) was located in the third and fourth quadrants. The diameter at the entrance of the right ISV ranged from 2.7-3.8 mm. When the right ISV drained into the inferior vena cava, 83% of cases were located within 40 mm distance below the ostium of the right renal vein, while during draining into the right renal vein, the average distance from the main vein was 6.3 mm.
Conclusion: This study concluded that MCT can be used to evaluate the anatomical characteristics of the right ISV. The optimal interventional approach was through the jugular vein route to locate the ISV opening and improve the success rate of the embolization.

Purpose: To report reattachment rate (RR) of pars plana vitrectomy-suprachoroidal viscopexy (VIT-SCVEXY) for rhegmatogenous retinal detachment (RRD) repair. Additionally, this study compares the anatomic reattachment rate and functional outcomes of VIT-SCVEXY vs pars plana vitrectomy with traditional scleral buckle (PPV-SB) at postoperative month 3 and final follow-up.

Variability in radiation-related health risk and genetic susceptibility to radiation effects within a population is a key issue for radiation protection. Besides differences in the health and biological effects of the same radiation dose, individual variability may also affect dose distribution and its consequences for the same exposure. As exposure to radon progeny affects a large population and has a well-established dose-effect relationship, investigating individual variability upon radon exposure may be particularly important.

Objective: To demonstrate the effectiveness and safety of intraluminal endoscopic treatment of patients with adenomas of the major duodenal papilla and familial adenomatous polyposis.
Material And Methods: Over the past 4 years, 13 patients with adenomas of the major duodenal papilla and familial adenomatous polyposis underwent surgery in our hospital. Of these, 7 patients had exclusively extrapapillary adenomas without signs of spread to the ducts.
Background And Aims: Trait-based approaches have advanced our understanding of plant strategies, yet they often focus on leaf-level traits, overlooking the functional roles of stem anatomy and twig characteristics. We investigated intraspecific trait variation in Salix flabellaris, an alpine dwarf shrub, along climatic gradients in the Himalayas. Our goal was to identify distinct axes of trait variation related to stem, twig, and leaf traits, assess their environmental drivers, and evaluate population-specific growth responses to recent climate change.

Purpose Of Review: The expanding range of minimally invasive surgical therapies (MISTs) for benign prostatic hyperplasia (BPH) reflects a growing emphasis on individualized, anatomy-driven treatment that prioritizes symptom relief, reduced morbidity, and preservation of sexual function. This review provides a timely synthesis of MISTs, highlighting innovations in technique, key anatomical considerations, and evolving strategies for patient-centered care in the modern clinical setting.
Recent Findings: Recent studies highlight the expanding role of MISTs, such as UroLift, Rezūm, the temporary implanted nitinol device, Optilume BPH, transperineal laser ablation, and prostatic stents.
