まとめ
骨盤放射線治療を受けた小児がんの生存者は,特に高原状の尿流パターンと高まった余分な余分な余分な余分な機能を示しました. この集団では機能不全のスコア付けシステムは有用なスクリーニングツールではなかった.
科学分野:
- 小児腫瘍学
- 泌尿器科
- 放射線腫瘍学
背景:
- 小児がんの生存者における下尿路機能に対するマルチモダル治療の長期的効果は十分に記述されていません.
- 外部放射線治療 (EBRT) は,小児の固体腫瘍に対する一般的な治療法であり,しばしば骨盤領域を対象としています.
- 骨盤のEBRTがLUT機能に与える影響を理解することは,生存者のケアにとって極めて重要です.
研究 の 目的:
- 骨盤外線放射線療法 (EBRT) が小便管下部 (LUT) 機能に及ぼす効果を,小児がん生存者 (CCS) で調査する.
- 患者の報告したアウトカム,非侵襲性尿動力学研究,およびCCSとCCSの間の空白後の残留値 (PVR) を比較する.
主な方法:
- 小児の固体腫瘍に対する1年以上のCCSの前向きなコホート研究.
- 骨盤 EBRT 曝露に基づいてコホートに分かれました.
- 評価には,機能不全の排泄スコーリングシステム (DVSS) の調査,尿流検査,排泄後の残留 (PVR) 膀スキャンが含まれていた.
主要な成果:
- 骨盤放射線コホートは,異常な尿流パターン (81%対56%) と異常なPVR (OR 9. 0, p = 0. 002) を示した.
- 尿流のパターンの分布はグループによって著しく異なっており (p = 0.03),放射線コホートは"高原"の形状の曲線を示す可能性が高い (44%対6%).
- 探索的分析は,骨盤 EBRT 投与量と LUT 機能障害の間の潜在的な関連を示唆した.
結論:
- 外部放射線治療 (EBRT) は,骨盤放射線で治療された小児がん生存者 (CCS) の下部尿路機能に悪影響を及ぼすようです.
- 機能不全の空洞評価システム (DVSS) は,この集団におけるLUT機能不全に対する敏感なスクリーニングツールではないかもしれません.
- EBRTがLUT機能に与える影響を完全に解明し,改善されたスクリーニング方法を開発するには,さらなる研究が必要です.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

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.

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
