Urinary Bladder01:23

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...

Anatomy of the Genitourinary System II: Bladder and Urethra

214
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...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

236
The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...

Imaging Studies VI: Voiding Cystourethrography and Cystography

136
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...

Urodynamic Studies: Uroflowmetry01:19

Urodynamic Studies: Uroflowmetry

635
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...

The Micturition Reflex01:26

The Micturition Reflex

1.1K
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...

Area of Science:

  • Neuroscience
  • Urology
  • Medical Imaging

Background:

  • Neurogenic lower urinary tract dysfunction (NLUTD) diagnosis and treatment are limited by incomplete understanding of neural regulation.
  • Identifying biomarkers for bladder sensation is crucial for advancing NLUTD care.

  • To apply a transfer learning approach to infer bladder fullness sensation from functional magnetic resonance imaging (fMRI) data.
  • To investigate the potential of fMRI-based biomarkers for NLUTD.

Main Methods:

  • Utilized a transfer learning model to analyze fMRI data.
  • Focused on inferring bladder fullness sensation from brain activity patterns.

Main Results:

  • The transfer learning model successfully represented fMRI scans in an embedding space.
  • The model's prediction of bladder fullness sensation was not significantly better than random chance.

Conclusions:

  • While the approach showed promise in data representation, it did not yield significant predictive power for bladder sensation.
  • Further research is needed to develop robust fMRI-based biomarkers for NLUTD.
