The Micturition Reflex01:26

The Micturition Reflex

1.6K
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...

Urodynamic Studies: Uroflowmetry

1.4K
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

396
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 Bladder01:23

Urinary Bladder

2.1K
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

533
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...

Psychosexual Stages of Personality: Anal01:26

Psychosexual Stages of Personality: Anal

2.6K
Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...

Summary

Children with overactive bladder (OAB) exhibit more behavioral issues, especially hyperactivity, compared to those with voiding postponement (VP). Urge incontinence is strongly linked to OAB in pediatric patients.

Area of Science:

  • Pediatric Urology
  • Child Psychology

Background:

  • Overactive bladder (OAB) and voiding postponement (VP) present with urinary urgency but differ in pathophysiology.
  • Understanding these differences is crucial for accurate diagnosis and treatment in children.

Purpose of the Study:

  • To compare clinical, psychological, and sociodemographic features of children experiencing urgency due to OAB versus VP (UrVP).

Main Methods:

  • Retrospective cross-sectional study of 101 children (5-14 years) with urinary urgency.
  • Evaluated symptoms using DVSS, constipation with Rome IV criteria, and psychological aspects with SDQ.
  • Classified patients into OAB (>3 voids/day) or UrVP (≤3 voids/day) groups.

Main Results:

  • OAB prevalence was 60.4%. No significant differences in age or constipation prevalence between groups.
  • Children with OAB showed higher behavioral hyperactivity and externalizing symptoms.
  • Multivariate analysis identified behavioral hyperactivity, urge incontinence, and MVV/EBC as independent factors for OAB diagnosis.

Conclusions:

  • Children with OAB demonstrate more behavioral problems, particularly hyperactivity, than those with UrVP.
  • Sociodemographic characteristics were similar between groups.
  • Urge incontinence strongly associated with OAB and lower MVV/EBC in pediatric patients.
