[Etiological work-up of complex voiding disorders (CVD) in boys; evaluation of the imaging strategy based on a retrospective study of 58 files].
The strategy of radiological investigations in males with severe voiding disorders has not been clearly established. To define the most effective strategy, a retrospective study of 58 files of boys investigated for severe voiding disorders (excluding neurogenic bladder) was performed. The following investigations were performed in this series: intravenous urography (IVU) completed by voiding cystourethrogram (VCUG) (41%), VCUG alone or associated with urinary ultrasound (30%), IVU alone (20.5%) ultrasound alone (1.5%) and ultrasound completed by VCUG or IVU (7%). When prescribed first, VCUG was always sufficient for accurate diagnosis; in contrast, a second investigation was usually necessary when IVU (66%) or ultrasound (80%) were performed first. The interpretability of the voiding urethrogram was also higher with VCUG (90%) than with IVU (66%); the sensitivity was 94% for VCUG and only 69% for IVU and 8% for ultrasound. This study confirms that VCUG combined with urinary ultrasound is the most reliable way to radiologically investigate male severe voiding disorders.
