Summary
Catheterized uroflowmetry effectively diagnoses detrusor acontractility in men with urinary retention. This simple test helps determine bladder function, improving management for patients requiring pressure-flow studies (PFS).
Area of Science:
- Urology
- Lower Urinary Tract Physiology
Background:
- Detrusor acontractility is a common cause of urinary retention in older men.
- Accurate diagnosis is crucial for appropriate management.
- Pressure-flow studies (PFS) are the gold standard but can be invasive.
Purpose of the Study:
- To assess the diagnostic efficacy of uroflowmetry performed via an indwelling catheter for detrusor acontractility.
- To determine if catheterized uroflowmetry can serve as a simpler alternative for initial assessment.
Main Methods:
- 50 men (51-85 years) with indwelling catheters and urinary retention were studied.
- Voiding through the catheter was measured after bladder filling.
- Results were compared with standard pressure-flow studies (PFS).
Main Results:
- A statistically significant correlation was found between detrusor acontractility and peak flow rate (Qmax) <10 ml/s during catheterized uroflowmetry (p=0).
- Catheterized uroflowmetry demonstrated high accuracy in identifying detrusor acontractility.
Conclusions:
- Catheterized uroflowmetry is a quick, noninvasive, and inexpensive method for evaluating lower urinary tract function.
- This test is highly useful for differentiating detrusor acontractility from other causes of urinary retention.

9.4K
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...

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...

01:26The Micturition Reflex
4.1K
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...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
