=== - 主要設計目的: - Urocross Retrieval Sheath:以取出非永久性植入物為主,同時可做為泌尿道手術之通路(兼具「植入物取出工具」與「通道」的雙重角色)。這點是它與純粹為碎石設計的 UAS 最大的功能差別。medeonbiodesign.com<ref>{{cite web|title=medeonbiodesign.com|url=https://www.medeonbiodesign.com/announcements/urocross-retrieval-sheath%E5%8F%96%E5%87%BA%E8%A3%9D%E7%BD%AE%E7%8D%B2%E7%BE%8E%E5%9C%8Bfda-510k-%E6%A0%B8%E5%87%86%EF%BC%8C%E7%82%BAurocross-expander-system%E9%A6%96%E6%AC%BE%E7%8D%B2%E5%87%86/|publisher=medeonbiodesign.com|access-date=2025-12-01}}</ref>。 - 傳統 UAS:專注於提供長度/剛性/低摩擦通道以支援碎石、鏡內操作與降低腎內壓(多為單一用途)。PLOS<ref>{{cite web|title=PLOS|url=https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0193600|publisher=journals.plos.org|access-date=2025-12-01}}</ref>。 === * 對碎石操作的影響: - 使用 UAS 可降低腎內壓、加速碎石片和灌流液的排出,常被認為能提高碎石清除率並便於重複進出。但是系列 Meta/研究顯示 UAS 的臨床效益(例如是否降低整體併發症)在不同研究中有差異,且存在輸尿管損傷風險。PLOS<ref>{{cite web|title=PLOS|url=https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0193600|publisher=journals.plos.org|access-date=2025-12-01}}</ref>。 - 近年技術(如具吸引/可彎曲新型 sheath)顯示「加吸引」或「更靈活的 UAS」可進一步改善碎石清除率且減少併發症,但要看具體產品設計與臨床證據。PubMed<ref>{{cite web|title=PubMed|url=https://pubmed.ncbi.nlm.nih.gov/30120500/|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2025-12-01}}</ref>。 * 相容性與臨床流程: - Urocross 明確標榜能與常見的軟式膀胱鏡配合,用以取出植入物,對泌尿科常規流程阻力較小(不像某些新系統需要完全不同配套設備)。若用作碎石通道,需評估長度、內徑(Fr)、是否支援連續抽吸或灌流等參數來與現有 UAS 比較。medeonbiodesign.com<ref>{{cite web|title=medeonbiodesign.com|url=https://www.medeonbiodesign.com/investors-announcements/?lang=zh|publisher=medeonbiodesign.com|access-date=2025-12-01}}</ref>。 * 風險面: - UAS 的一般風險:輸尿管黏膜損傷、穿孔、術中輸尿管壓力變化、操作器械摩擦創傷等。文獻建議在使用時權衡優劣並注意規格/口徑選擇。PLOS<ref>{{cite web|title=PLOS|url=https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0193600|publisher=journals.plos.org|access-date=2025-12-01}}</ref>。 - Urocross 作為檢索/取出工具,關鍵在於「安全有效地鉤取/保護植入物取出過程」,及它在作為碎石通道時是否會比專用 UAS 在通暢性或壓力管理上有差距 — 這需要具體臨床資料(廠商提供或獨立比較研究)來驗證。medeonbiodesign.com<ref>{{cite web|title=medeonbiodesign.com|url=https://www.medeonbiodesign.com/announcements/urocross-retrieval-sheath%E5%8F%96%E5%87%BA%E8%A3%9D%E7%BD%AE%E7%8D%B2%E7%BE%8E%E5%9C%8Bfda-510k-%E6%A0%B8%E5%87%86%EF%BC%8C%E7%82%BAurocross-expander-system%E9%A6%96%E6%AC%BE%E7%8D%B2%E5%87%86/|publisher=medeonbiodesign.com|access-date=2025-12-01}}</ref>。
