まとめ
標準化された膀の形状は,小児の脊椎間板症患者で確立されました. トラベキュレーションと"クリスマスツリー"の形は 膀圧力の上昇と相関していますが 他の機能障害の指標とは必ずしも関係ありません
科学分野:
- 小児泌尿器科
- 神経神経学
- 医療用イメージング
背景:
- 脊椎間板症は 膀の機能不全を引き起こします
- この集団における膀の形状の標準化用語は欠けている.
- 膀の形状は 根本的な機能不全を示す可能性があります
研究 の 目的:
- 小児の膀の形状に関する標準化された用語を,光鏡画像で提案する.
- 膀の形状と充填圧の関連性を評価する.
- 膀の形状が他の膀機能障害の測定値と相関するかどうかを判断する.
主な方法:
- ビデオ尿動力学を受けた小児脊椎病患者の横断的な研究.
- 無監督のクラスター分析と専門医による膀の形状の分類 (丸い,長方形, "クリスマスツリー",滑らかな, トラベキュラ).
- 膀の充填圧と臨床機能障害の比較
主要な成果:
- 417人の小児患者が分析されました.
- トラベキュラと"クリスマスツリー"の膀は,滑らかな膀と比較して,かなり高い充填圧を示しました.
- 膀の形状の差異は,膀回流,漏れ,およびデトルーザー外側軟骨管の不協和症と関連していたが,水解症または機能障害の重症度とは一貫して関連していなかった.
結論:
- 小児の脊椎間板症の標準化された膀形状の命名法が確立された.
- 膀の輪郭と"クリスマスツリー"の形状は,より高い充填圧に関連しています.
- 膀の形状だけでは,すべてのタイプの膀機能不全や重症性を一貫して予測するには不十分です.

Urodynamic Studies: Uroflowmetry
534
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Urinary Bladder
1.5K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

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...
