Insights

Contrast-enhanced voiding ultrasonography (ceVUS) effectively detects vesicoureteric reflux (VUR) in children. This radiation-free method is safe and reliable for diagnosing VUR and evaluating the urinary tract.

Area of Science:

  • Pediatric Urology
  • Diagnostic Imaging

Background:

  • Vesicoureteric reflux (VUR) is a common complication of pediatric urinary tract infections (UTIs), affecting 30-50% of children.
  • Contrast-enhanced voiding ultrasonography (ceVUS) is a radiation-free imaging technique for VUR detection.

Purpose of the Study:

  • To review the literature and present findings from a pilot study on ceVUS for VUR detection in children.
  • To evaluate the efficacy of second-generation ultrasound contrast agents in ceVUS.

Main Methods:

  • Retrospective review of 31 ceVUS examinations in children aged 2 months to 18 years.
  • Utilized second-generation ultrasound contrast agent (SonoVue).

Main Results:

  • ceVUS detected VUR in 64.5% of children (20/31), involving 51.6% of nephroureteral units.
  • VUR grades ranged from II to IV.
  • Identified "spinning top urethra" in two girls, indicating functional bladder issues.

Conclusions:

  • ceVUS with second-generation contrast agents is a safe, effective, and reliable alternative for diagnosing VUR in children.
  • The method is suitable for evaluating the pediatric distal urinary tract without radiation exposure.

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...

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.

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 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...

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
