まとめ
以前のコントラストアレルギーは,尿路の手続きにおけるヨウ素濃縮コントラストメディア (ICM) に対する重度の有害反応 (SARs) を予測しません. 定期的な手術前アレルギー予防 (PAP) も,これらのまれな反応を防ぐことはできません.
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.
- 放射線学 放射線学
- アネステシオロジー アネステシオロジー
背景:
- ヨウ素濃縮コントラストメディア (ICM) はイメージングを強化しますが,重度のアレルギー反応 (SARs) を引き起こす可能性があります.
- コントラスト媒体や貝類に対する以前のアレルギーは,ICM反応の信頼性の高い予測要因ではありません.
- 前回のアレルギーの予測的価値と,尿路の手続きで使用されるICMのための術前アレルギー予防 (PAP) の有効性は不明です.
研究 の 目的:
- ICM (a-ICM) またはPAPに対する以前のアレルギーが,尿管顕微鏡検査 (URS) または皮膚経性腎石切除術 (PCNL) を受けている患者のSARを予測できるかどうかを評価する.
主な方法:
- URSまたはPCNLを22年間にわたって受けた12,020人の患者を遡及的に調査した.
- a-ICMの患者は,PAPの状態と処置の種類に基づいて分析されました.
- 主なアウトカムには,手術後のICU入院と,SARsのサロゲートとして手術中のエピネフリン使用が含まれていました.
主要な成果:
- すべての処置において,低SAR率0.5%が観察されました.
- a-ICM (0.4%対0.5%,p=1.00) の患者と患者との間にSAR率の有意な差は認められなかった.
- ロジスティック回帰では,SARとa-ICMまたはPAPとの間に有意な相関関係がないことが判明しました. アメリカ麻酔学会 (American Society of Anesthesiologists) のスコアが高く,女性の性別,長期間の入院がSARと相関していた.
結論:
- URSまたはPCNL中にICMに対する重度の有害反応はまれである.
- 以前のコントラストアレルギーは,SARsを予測しません.
- 術前アレルギー予防は,この患者コホートにおいて,SARを日常的に予防することはありません.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
