科学领域:
- 泌尿和妇科 泌尿和妇科
- 运动医学 运动医学
- 盆地地板生理学 盆地地板生理学
背景情况:
- 跑步引起的压力尿失禁 (RI-SUI) 是影响女性运动员的一个常见问题.
- 了解RI-SUI和没有RI-SUI的跑步者的骨盆底肌 (PFM) 差异对于有针对性的干预至关重要.
研究的目的:
- 为了比较底肌肉 (PFM) 形态和功能,在女性跑步者和没有跑步诱导的压力尿失禁 (RI-SUI).
- 确定可能导致跑者RI-SUI的生物力学因素.
主要方法:
- 涉及经验丰富的女性跑步者的横截面观测研究.
- 参与者被分为两组:具有RI-SUI (n=19) 和没有RI-SUI (n=20) 的参与者.
- 骨盆底肌 (PFM) 的特性 (主动和被动) 使用阴道内动力测量和跨膜超声波进行了评估;尿道和PFM的形态也得到了评估.
主要成果:
- 与大陆跑者相比,RI-SUI的跑者在最大自愿收缩 (MVC) 期间表现出明显更高的PFM收缩力发展.
- 相反,RI-SUI的参与者在组织延长过程中显示出明显较低的被动PFM力.
- 在PFM激活期间,在RI-SUI组中观察到更高的膀部升高以及更大的尿道壁和升降器间隙区域的趋势.
结论:
- 经历RI-SUI的女性跑步者表现出增强的PFM收缩功能,但减少了被动支持.

Muscles of the Pelvic Floor and Perineum
1.4K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Anatomy of the Genitourinary System II: Bladder and Urethra
126
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...

Urinary Bladder
907
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...

Urodynamic Studies: Uroflowmetry
80
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...

Disorders of the Urinary System
357
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...
