まとめ
制御可能な尿管顕微鏡腎疏散 (SURE) は,残留石の量を大幅に減らし,医療費の消費事件と石のイベントを長期的に低下させます. 残留石の量は,腎石治療後の将来の合併症の重要な予測要因です.
科学分野:
- 泌尿器科 泌尿器科とは
- ネフロロジーはネフロロジーを用います.
- 医療技術 医療技術について
背景:
- 腎石 (腎結石) は重大な健康上の負担となり,効果的な治療戦略が必要となります.
- 治療後の残留石の量は,患者の治療結果と医療利用に影響を与える重要な要因です.
- 標準尿管顕微鏡 (URS) は一般的な治療法ですが,残留石は合併症を引き起こす可能性があります.
研究 の 目的:
- 標準的なURSと比較して,制御可能な尿管顕微鏡腎疏散 (SURE) の後の2年間の医療費消費と石事件 (SE) を評価する.
- 残留石の量と,その後のヘルスケア消費イベント (HCEs) との関連性を決定する.
- 腎石治療後のHCEとSEの予測要因を特定するために.
主な方法:
- ロジスティック回帰は,HCE (緊急治療室訪問,入院,外科再治療) とSEの予測要因を特定するために使用されました.
- カプラン・マイヤー生存分析は,SUREとURSのグループ間のイベントの発生率を比較するために使用されました.
- 容量測定分析により,治療後30日および2年後の残留石の量を評価した.
主要な成果:
- 2年後の残留石の量は,HCEとSEの両方を有意に予測した; 100 mm3の増加は,HCEのリスクを50-54%とSEのリスクを70%増加させた.
- SUREグループは,URSグループと比較して,HCE (3対20イベント,p=0.0004) が著しく少なく,イベントフリー生存期間が長かった.
- SUREグループではSEが少なく,統計的に有意ではないが,イベントフリー生存期が長くなることが観察された.
結論:
- 残留石の量は,腎石除去療法の有効性を評価し,下流合併症を予測するための重要な指標です.
- SUREは,標準的なURSと比較して,ヘルスケア消費イベントの発生率とリスクを大幅に削減します.
- 高品質の体積分析は,腎石管理における治療効果の評価に不可欠です.

Types of Building Stone

Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

Quarrying of Stone
601
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

Stone Masonry
510
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...
