Urodynamic Studies: Uroflowmetry

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 Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Imaging Studies VI: Voiding Cystourethrography and Cystography

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...

Urologic Endoscopic Procedure: Cystoscopic Examination

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Imaging Studies II: Ultrasonography

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Urinary Bladder

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...

Context:

The AMS-800 artificial urinary sphincter was the sole option for refractory stress urinary incontinence for 25 years.
High complication rates with the AMS-800 prompted design modifications, leading to the FlowSecure artificial sphincter.
The FlowSecure device is an adjustable, saline-filled prosthesis without contrast, necessitating alternative imaging techniques.

Purpose:

To introduce the FlowSecure artificial urinary sphincter as a novel treatment for stress urinary incontinence.
To outline the recommended evaluation methods for the FlowSecure device, emphasizing ultrasound's role.
To guide functional assessment for optimizing FlowSecure device pressure settings.

Summary:

The FlowSecure artificial urinary sphincter is an adjustable, saline-filled device for managing stress urinary incontinence.
Unlike the AMS-800, FlowSecure cannot be monitored with plain X-rays due to its saline content.
Ultrasound is the primary imaging modality for assessing FlowSecure device integrity, post-void residue, and urethral occluding pressure.

Impact:

Provides a new therapeutic option for patients with stress urinary incontinence unresponsive to other treatments.
Establishes ultrasound as the essential tool for monitoring and adjusting the FlowSecure artificial sphincter.
Highlights the importance of integrating ultrasound findings with clinical history and flow rate measurements for optimal patient management and continence.
Facilitates personalized treatment by enabling adjustment of system pressure to the minimum required for total continence.
