Summary
This summary is machine-generated.Contrast-enhanced urosonography (CE-VUS) is a highly sensitive alternative to radiographic retrograde cystourethrography (RCUG) for detecting vesicoureteral reflux (VUR) in young dogs. This imaging technique shows excellent concordance with the standard method.
Area Of Science
- Veterinary Medicine
- Diagnostic Imaging
- Urology
Background
- Vesicoureteral reflux (VUR) is a common condition in young dogs.
- Radiographic retrograde cystourethrography (RCUG) is the current standard for VUR diagnosis but is invasive.
- There is a need for non-invasive and accurate diagnostic methods for VUR in veterinary medicine.
Purpose Of The Study
- To evaluate contrast-enhanced urosonography (CE-VUS) as a non-invasive alternative to RCUG for detecting VUR in young dogs.
- To compare the diagnostic performance of CE-VUS against RCUG.
Main Methods
- Prospective study involving 62 young dogs (6 weeks to 12 months).
- VUR assessment using both RCUG and CE-VUS on 124 ureterorenal units.
- CE-VUS involved instilling an ultrasound contrast agent into the bladder via catheter following baseline ultrasound.
Main Results
- CE-VUS and RCUG findings were concordant in 94.35% of ureterorenal units.
- CE-VUS demonstrated high sensitivity (94.12%) and specificity (94.39%) for VUR detection compared to RCUG.
- High negative predictive value (99.02%) indicates CE-VUS is reliable for ruling out VUR.
Conclusions
- Contrast-enhanced urosonography (CE-VUS) is a highly sensitive and specific imaging modality for diagnosing vesicoureteral reflux (VUR) in young dogs.
- CE-VUS offers a valuable, less invasive alternative to RCUG for VUR detection in canine patients.
- The high concordance and accuracy support the clinical utility of CE-VUS in veterinary urology.

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...
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...
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...
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...
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...
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...
