O3302: Parental Perception of Contrast Enhanced Voiding Ultrasonography Urodynamics vs Fluoroscopic Urodynamics

Background: Contrast enhanced voiding ultrasonography (CeVUS) has not been reported to be used during urodynamics (UDS). We reported on the feasibility of this and aimed to understand how parents perceived their child’s experience of undergoing CeVUS during UDS compared to fluoroscopic (fluoro) UDS.

Methods: Children who underwent both fluoro UDS and CeVUS UDS were recruited. Parents were asked to complete a questionnaire to evaluate their experience with both studies. Demographics including gender, age at study, and sedation use were collected to account for differences in perception. Statistical analysis was performed.

Results: 47 patients were included: 28 girls, 19 boys. Diagnoses included myelomeningocele (70%), closed spinal dysraphism (13%), low/tethered cord (11%), posterior urethral valve (2%), cloacal anomaly (2%), and cerebral palsy (2%). The mean age at fluoro UDS was significantly lower than age at ceVUS (3.1 vs 8.4 years, p< 0.0001). No patients required sedation for either study.

47 parents (100%) were satisfied/very satisfied with their CeVUS experience; 42 parents (89%) preferred CeVUS, 3 (6%) preferred fluoro UDS, and 2 (4%) were neutral. On average, parents perceived CeVUS to be more comfortable (69%) and produce better results (66%) than fluoro UDS. The majority felt that both studies allowed same contact with their child (56%) and were the same speed (57%). However 28% felt CeVUS was faster and allow more contact with their child (Fig 1). 22 parents (47%) specifically noted no radiation as the reason why they preferred CeVUS over fluoro.

When looking at age’s influence on preference, those who preferred fluoro UDS underwent CeVUS UDS at an older age than those who preferred CeVUS UDS (15.0 vs 8.3 years, p=0.03). In contrast, the age at fluoro UDS was similar for the 2 preference groups (4.8 years [fluoro pref] vs 3.1 years [CeVUS pref], p=0.35). Gender’s influence on preference approached significance (p=0.06); 3 parents who preferred fluoro UDS had boy children.

Conclusion: The majority of parents preferred CeVUS over fluoro UDS. CeVUS was perceived to be more comfortable and provide better results. Many parents highlighted no radiation as a factor in preference of CeVUS over fluoro. Older age at time of CeVUS UDS may have influenced fluoro UDS preference.
