Beeldvormend Onderzoek VI: Mictie-cysto-urethrografie en Cystografie

A Voiding Cystourethrogram, or VCUG, is an imaging study that evaluates bladder function, the bladder neck, and the urethra. It helps detect vesicoureteral reflux, bladder neck obstruction, and post-void residual urine.

The procedure begins with inserting a lubricated catheter through the urethra into the bladder. A contrast agent is then introduced to highlight the urinary tract.

Fluoroscopic images are captured as the bladder fills, allowing real-time assessment of its structure.

The catheter is then removed, and the patient is asked to urinate. During urination, additional images are taken to evaluate urine flow through the bladder neck and urethra.

After urination, another image is taken to check for residual urine.

Next, cystography is similar to VCUG; it focuses primarily on diagnosing bladder abnormalities using static X-ray images without capturing real-time images during urination.

In cystography, a contrast agent is injected into the bladder through a urinary catheter to highlight structural defects, such as diverticula or trauma.
