Urinary Bladder01:23

Urinary Bladder

3.9K
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

2.8K
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: Uroflowmetry

6.3K
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

3.2K
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...

Anatomy of the Genitourinary System II: Bladder and Urethra

2.3K
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...

Disorders of the Urinary System01:20

Disorders of the Urinary System

1.4K
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...

Summary
This summary is machine-generated.

Animated biofeedback therapy offers significant clinical and electromyographic improvements for dysfunctional voiding in children. Successful treatment outcomes are linked to the absence of constipation and normal perineal relaxation post-therapy.

Area of Science:

  • Pediatric Urology
  • Pelvic Floor Rehabilitation
  • Urodynamics

Background:

  • Dysfunctional voiding (DV) is a common pediatric urological condition.
  • Treatment often involves behavioral therapies and biofeedback.
  • Assessing clinical and electromyographic outcomes is crucial for treatment efficacy.

Purpose of the Study:

  • To evaluate the clinical and electromyographic outcomes of dysfunctional voiding treatment using animated biofeedback.
  • To identify clinical and electromyographic variables associated with successful treatment outcomes.

Main Methods:

  • A cross-sectional study included 27 girls with dysfunctional voiding treated with animated biofeedback between 2010-2015.
  • Efficacy was assessed using uroflowmetry, electromyography (EMG), and validated clinical questionnaires.
  • Inclusion criteria included no myelodysplasia or anatomical malformations, and a minimum of 3 biofeedback sessions.

Main Results:

  • Overall, clinical and uroflowmetry parameters improved in patients receiving biofeedback.
  • Complete symptom resolution occurred in 33.5%, with 37% showing improvement ( >50% symptom reduction).
  • Electromyography showed normal perineal relaxation in 74% of patients. Baseline constipation was associated with lower success rates (p=0.019).

Conclusions:

  • Animated biofeedback provides significant clinical cure or improvement in 69% of patients with dysfunctional voiding.
  • Electromyographic resolution, indicating normal perineal relaxation, was achieved in 74% of patients.
  • Absence of constipation and absence of high post-void residual (PVR) are associated with higher treatment success rates.
