Urinary Bladder01:23

Urinary Bladder

3.4K
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...

Introduction to Urinary System01:13

Introduction to Urinary System

8.9K
The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra.
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

Disorders of the Urinary System01:20

Disorders of the Urinary System

1.2K
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...

Impact Loading01:19

Impact Loading

691
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
In cases of elastic deformation,...

Anatomy of the Genitourinary System II: Bladder and Urethra

1.6K
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 Tract Calculi I: Introduction01:28

Urinary Tract Calculi I: Introduction

522
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Area of Science:

  • Urology
  • Biomedical Engineering
  • Physiology

Background:

  • Understanding the bioelectrical activity of the urinary bladder is crucial for diagnosing and managing bladder dysfunction.
  • Current methods for assessing bladder function may not fully capture dynamic changes under physiological load.

Purpose of the Study:

  • To investigate the specific bioelectrical activity patterns of the urinary bladder walls during a functional load.
  • To identify key bioelectrical markers indicative of bladder wall state.

Main Methods:

  • Biopotentials from the ureter and urinary bladder were recorded in five healthy young adults using a high-sensitivity electroencephalograph (Neuro-Spectrum NeuroSoft-21).
  • Functional load was induced via water loading.
  • Data analysis involved spectral analysis and correlation with background load, utilizing STATISTICA 10 software.

Main Results:

  • A significant correlation (coefficient > 0.8) was observed between background spectra at rest and under load.
  • Three specific frequencies (0.7, 1.5, and 1.7 Hz) within the 0.5 to 2 Hz range showed clear temporal amplitude changes.
  • Water loading increased bladder wall biopotential activity after 10 minutes and altered the harmonic pattern compared to the resting state.

Conclusions:

  • Functional load significantly alters the bioelectrical activity spectrum of the bladder walls.
  • The identified frequencies (0.7, 1.5, and 1.7 Hz) are potential biomarkers for assessing the functional state of the bladder wall.
  • The electroencephalograph method is suitable for registering bladder biopotentials under functional load.
