Insights

Persistent cloaca (PC), a complex anorectal malformation, can be evaluated using contrast-enhanced ultrasound (CEUS). This study shows CEUS can visualize key structures and measure critical distances for preoperative planning in infants with PC.

Area of Science:

  • Pediatric Surgery
  • Medical Imaging
  • Congenital Anomalies

Background:

  • Persistent cloaca (PC) represents the most complex anorectal malformation.
  • Contrast-enhanced ultrasound (CEUS) is a safe imaging modality for pediatric assessments.
  • CEUS application in cloacal malformation diagnosis is limited.

Observation:

  • This study explored the utility of CEUS for preoperative evaluation in an infant with PC.
  • CEUS successfully visualized the uterine, vaginal, bladder, urethral, and rectal structures.
  • The technique also identified the rectovaginal fistula and measured critical anatomical dimensions.

Findings:

  • CEUS accurately delineated the anatomy of persistent cloaca, including the common channel.
  • Measurements of the common channel length, bladder neck to common channel distance, and distal urethra to perineum distance were obtained.
  • This represents a novel application of CEUS for preoperative assessment in PC.

Implications:

  • CEUS offers a non-invasive method for detailed anatomical assessment in persistent cloaca.
  • This imaging technique may aid in surgical planning and improve outcomes for affected infants.
  • Further research can validate CEUS as a standard tool for evaluating complex anorectal malformations.

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 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...

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 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.
