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...

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...

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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

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. Intravenous Urography (IVU)Intravenous...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

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...

Area of Science:

Pediatric Radiology
Medical Device Innovation

Background:

Voiding cystourethrography (VCUG) is a common diagnostic imaging procedure for evaluating the urinary tract in children.
Fluoroscopy time during VCUG can contribute to radiation exposure, necessitating methods for reduction.

Purpose of the Study:

To assess the feasibility of using a novel urine sensor during VCUG.
To determine the impact of the urine sensor on reducing fluoroscopy time in pediatric patients.

Main Methods:

A urine sensor, comprising an electrode and indicator, was tested in children under 5 years old undergoing VCUG.
The sensor was placed near the urethral opening, triggering fluoroscopy at the onset of voiding.
Fluoroscopy time and peak kV were recorded and compared to a control group.

Main Results:

The urine sensor reliably indicated the start of voiding.
VCUG with the urine sensor resulted in significantly shorter fluoroscopy times (1.99 min) compared to standard VCUG (4.33 min).
This reduction was observed in both overall patient groups and those with normal VCUG findings.

Conclusions:

The urine sensor is a feasible tool for VCUG procedures.
Utilizing this device can lead to a significant decrease in radiation exposure for pediatric patients undergoing VCUG.
