摘要

输尿管结石的常规半刚性输尿管镜治疗面临着诸如结石后退、术中视力差和肾内压升高等挑战。本研究评估了一种新型多通道负压吸尿管(输尿管opyelovisclear catheter, VCC)在输尿管镜碎石术中的安全性和有效性。为了比较VCC与传统硬输尿管镜的性能,本研究评估了VCC与传统半硬输尿管镜的手术时间、结石清除率和并发症发生率。前瞻性队列研究纳入42例输尿管结石(直径≤2.0 cm)患者,随机分为VCC组(n = 21)和传统输尿管结石组(n = 21)。VCC组采用一体化负压吸引和主动水循环系统,传统组采用标准半刚性输尿管镜。主要结果是手术时间,次要结果包括结石清除率、推入发生率、手术篮利用率和并发症发生率。VCC组手术时间明显缩短(39.95±10.24分钟比53.00±26.95分钟,p = 0.001),手术篮利用率明显降低(5%比57%,p = 0.001)

UreteroPyeloVisClear catheter: a new frontier in ureteroscopic lithotripsy for ureteral stones.

Conventional semirigid ureteroscopy for ureteral stones faces challenges such as stone retropulsion, poor intraoperative vision, and elevated intrarenal pressure. This study evaluates the safety and efficacy of a novel multi-channel negative pressure suction catheter (UreteroPyeloVisClear Catheter, VCC) in ureteroscopic lithotripsy. To compare the performance of VCC with conventional rigid ureteroscopy, this study evaluated operative time, stone clearance rates, and complication incidence between VCC and traditional semirigid ureteroscopy. A prospective cohort study included 42 patients with ureteral stones (diameter ≤ 2.0 cm), randomized into VCC (n = 21) and traditional (n = 21) groups. The VCC group utilized an integrated negative pressure suction and active water circulation system, while the traditional group used standard semirigid ureteroscopy. The primary outcome was operative time, with secondary outcomes including stone clearance rates, retropulsion incidence, basket utilization, and complication rates. The VCC group demonstrated significantly shorter operative time (39.95 ± 10.24 vs. 53.00 ± 26.95 min, p = 0.001) and reduced basket utilization (5% vs. 57%, p < 0.001). Stone retropulsion rates were lower in the VCC group (5% vs. 14%, p = 0.294), though not statistically significant. Both groups achieved 100% stone-free rates at 1 month. Postoperative pain scores (VCC: 0.90 ± 1.36 vs. traditional: 1.24 ± 1.49) and complication rates (0% vs. 5%) showed no significant differences. The VCC significantly reduces operative time and reliance on auxiliary instruments while maintaining safety and stone-free outcomes. Its innovative design addresses key limitations of traditional ureteroscopy, offering a promising advancement for ureteral stone management.

期刊介绍: Official Journal of the International Urolithiasis Society The journal aims to publish original articles in the fields of clinical and experimental investigation only within the sphere of urolithiasis and its related areas of research. The journal covers all aspects of urolithiasis research including the diagnosis, epidemiology, pathogenesis, genetics, clinical biochemistry, open and non-invasive surgical intervention, nephrological investigation, chemistry and prophylaxis of the disorder. The Editor welcomes contributions on topics of interest to urologists, nephrologists, radiologists, clinical biochemists, epidemiologists, nutritionists, basic scientists and nurses working in that field. Contributions may be submitted as full-length articles or as rapid communications in the form of Letters to the Editor. Articles should be original and should contain important new findings from carefully conducted studies designed to produce statistically significant data. Please note that we no longer publish articles classified as Case Reports. Editorials and review articles may be published by invitation from the Editorial Board. All submissions are peer-reviewed. Through an electronic system for the submission and review of manuscripts, the Editor and Associate Editors aim to make publication accessible as quickly as possible to a large number of readers throughout the world.
