Voiding cystourethrography in infants and children: a new technique

Area of Science:

• Urology
• Medical Imaging

Background:

• Voiding cystourethrography (VCUG) is a standard diagnostic imaging procedure.
• Traditional VCUG may face challenges in visualizing urethral pathology and voiding dynamics.

Purpose of the Study:

• To describe and illustrate a novel technique for voiding cystourethrography.
• To evaluate the efficacy of a small-caliber catheter in preserving visualization of urethral pathology during VCUG.

Main Methods:

• A modified VCUG technique employing a small caliber (3.5 Fr.) catheter that remains indwelling throughout the examination.
• Contrast medium infusion under pressure using a standard blood administration set.

Main Results:

• The described technique effectively prevents obscuration of urethral pathology.
• Complete visualization of the voiding phase was achieved in all examinations performed with this method.

Conclusions:

• This small-caliber, indwelling catheter technique offers a reliable approach to voiding cystourethrography.
• It ensures optimal visualization of urethral structures and successful assessment of voiding function.
