Insights

Overactive bladder (OAB) affects 9.01% of Chinese children aged 5-14, with prevalence decreasing with age. Risk factors include obesity, UTIs, and late elimination communication (EC) start.

Area of Science:

  • Pediatrics
  • Urology
  • Public Health

Background:

  • Overactive bladder (OAB) is a common condition in children, impacting quality of life.
  • Understanding OAB prevalence and risk factors in specific populations is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of overactive bladder (OAB) in Chinese children aged 5 to 14 years.
  • To identify risk factors associated with OAB in this pediatric population.

Main Methods:

  • A cross-sectional study involving 10,133 children aged 5-14 in five Chinese provinces.
  • Anonymous, self-administered questionnaires collected data on demographics, urinary tract infections (UTIs), lower urinary tract symptoms (LUTS), family history, bowel symptoms, and elimination communication (EC) start time.

Main Results:

  • The overall prevalence of OAB was 9.01%, decreasing with age (12.40% at 5 years to 4.55% at 14 years).
  • Late-onset EC, obesity, history of UTI, nocturnal enuresis (NE), family history of LUTS, constipation, and fecal incontinence were associated with higher OAB prevalence.

Conclusions:

  • Obesity, UTI history, NE, family history of LUTS, and bowel symptoms are significant risk factors for childhood OAB.
  • Initiating elimination communication (EC) before 12 months of age may help reduce OAB prevalence in children.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Nursing Assessment of the Genitourinary System I: Health History

The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

The Micturition Reflex01:26

The Micturition Reflex

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

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...

Urinary Bladder01:23

Urinary Bladder

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...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
