Insights

Dysfunctional voiding is common in children with urinary issues like incontinence and urgency. Pelvic floor muscle training effectively treats this condition, improving bladder function and reducing urinary tract infections.

Area of Science:

  • Pediatric Urology
  • Urodynamics
  • Child Health

Background:

  • Dysfunctional voiding is a significant cause of lower urinary tract symptoms (LUTS) in children.
  • It is frequently associated with urinary tract infections (UTIs) and vesicoureteral reflux (VUR).
  • Urgency frequency syndrome and urinary incontinence are common LUTS in pediatric patients.

Purpose of the Study:

  • To analyze videourodynamic investigations in children experiencing urgency frequency syndrome and/or urinary incontinence.
  • To determine the prevalence of dysfunctional voiding in this pediatric population.
  • To assess the effectiveness of treatments for dysfunctional voiding.

Main Methods:

  • Videourodynamic studies were conducted on 40 children aged 1-13 years with urgency frequency syndrome and/or incontinence.
  • Patient data were analyzed alongside clinical characteristics and underlying pathophysiology.
  • Treatment outcomes were evaluated using post-treatment urodynamic studies in a subset of patients.

Main Results:

  • Dysfunctional voiding was diagnosed in a high percentage of children across various conditions, including detrusor overactivity (75.7%), VUR (73.3%), urinary incontinence (63%), episodic UTIs (77%), and diurnal enuresis (100%).
  • Children with dysfunctional voiding exhibited significantly higher voiding pressures compared to those without (p < 0.05).
  • Biofeedback pelvic floor muscle training and antimuscarinic agents effectively reduced detrusor pressure, increased bladder capacity and flow rate, and improved VUR grade in treated children.

Conclusions:

  • Dysfunctional voiding is highly prevalent in children presenting with urgency, frequency, and incontinence.
  • Biofeedback pelvic floor muscle training demonstrates efficacy in treating dysfunctional voiding in pediatric patients.
  • Videourodynamics is a valuable tool for diagnosing and managing these conditions.

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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

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...
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 urine...

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,...
Disorders of the Urinary System01:20

Disorders of the Urinary System

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...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

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.
