まとめ
新生児の腎臓の通常の超音波検診は,尿道逆流の検出には効果がない. ヒドロネフローシスやリフルーシスの多くの乳児は,最初のスキャンでわずかな腎臓の膨張しか示されず,早期発見が困難でした.
科学分野:
- 小児腎臓病理学について
- 診断用イメージング
- 泌尿器科 泌尿器科とは
背景:
- 尿路逆流は,腎臓損傷 (逆流性腎不全) を引き起こす可能性があります.
- 新生児の尿路異常に対する早期の非侵襲的スクリーニングは望ましい.
- 超音波は,幼児の腎臓に対する一般的な非侵襲的イメージング技術です.
研究 の 目的:
- 尿道逆流のスクリーニングにおける新生児の超音波の感度を評価する.
- 新生児における先天性腎臓疾患を特定する際に,定期的な腎臓超音波の有効性を決定する.
主な方法:
- 1061人の未選択の新生児が腎臓の超音波検査を受け,その結果はビデオに収録された.
- 拡張した採取システムを持つ乳児は,さらなる調査 (MCUG,IVU,または放射性同位体研究) を受けました.
- 3歳の時,フォローアップ調査と記録検索が行われました.
主要な成果:
- 11人の子どもは,さらなる調査によって腎臓疾患が検出されました.
- 尿路感染症の後に,尿路リフルークスを持つ3人の追加の子供たちが,正常な新生児スキャンで特定されました.
- ヒドロネフロシスまたは尿路逆流の子供の半数以上は,新生児の超音波検査でごくわずかな (<5mm) 拡張しか示さなかった.
結論:
- 通常の新生児腎臓超音波検査は,尿路逆流の検出には役に立たない.
- 通常の新生児の超音波検査で重要な腎臓異常を検出する確率は低い.
- 新生児の微妙な尿路問題を検出するための超音波の感度は限られています.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

01:20Ultrasound I: Abdominal Ultrasonography
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
