まとめ
膀出口阻害 (BOO) のない男性では,老化により膀の収縮性が著しく低下する. BOOは,膀機能の年齢関連の変化を混乱させ,下部泌尿器系症状 (LUTS) の治療に影響を与える可能性があります.
科学分野:
- 泌尿器科
- 高齢者医療
- 生理学
背景:
- 高齢の男性における下部泌尿器系症状 (LUTS) に寄与する重要な要因です.
- 膀の収縮性の変化は,年齢に関連するLUTSの重要な側面です.
研究 の 目的:
- 男性患者の膀収縮性に対する老化の影響を調査する.
- 一般的なLUTS薬が,年齢に関連する膀収縮性変化にどのように影響するか評価する.
主な方法:
- 尿動力学の研究は,LUTSを患った40歳以上の男性に実施された.
- 膀出口阻害 (BOO) インデックスは,BOOと非BOOのグループに分けられた.
- 膀収縮性指数とピアソン相関は,年齢に関連する変化を分析した.
主要な成果:
- 年齢と最大フロー率は,BOOと非BOOの両グループで逆関係を示した.
- 膀収縮性は,非BOO群の年齢と有意に相関していた (p=0. 021).
- BOO群では年齢と膀収縮性の有意な相関は認められなかった (p=0. 057).
結論:
- 膀出口阻害 (BOO) は,年齢に関連する膀収縮性の評価を混乱させる可能性があります.
- BOOを除くと,膀の収縮性は年齢とともに明らかに低下します.
- 男性のLUTS治療における膀の収縮性に対する老化の影響は,BOOの存在に依存しています.

Urodynamic Studies: Uroflowmetry
527
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...

Anatomy of the Genitourinary System II: Bladder and Urethra
206
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...

The Micturition Reflex
1.0K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Urinary Bladder
1.4K
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...

Disorders of the Urinary System

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....
