voiding cystogram
Radiologic study examining bladder function and detecting urinary reflux by imaging during urination. Essential diagnostic tool in pediatric nephrology for evaluating recurrent UTIs.
Full Definition
A voiding cystogram is a specialized radiological examination that involves filling the bladder with contrast material and taking images before, during, and after urination to assess bladder anatomy, function, and detect vesicoureteral reflux. In pediatric patients, this study is crucial for evaluating children with recurrent urinary tract infections, suspected reflux, or voiding dysfunction. The procedure may use fluoroscopy (VCUG) or nuclear medicine techniques and requires careful preparation and sedation considerations in young children.
Usage
Usage note: Specify imaging modality (fluoroscopic vs nuclear) when relevant for dose considerations.
