Radiation Exposure During Pediatric Videourodynamics

Purpose: Videourodynamics is useful for evaluating and treating neurological disorders in children. Traditional urodynamic parameters can be obtained while simultaneous visualization of the urinary system can reveal anatomical anomalies. This additional information comes at the cost of radiation exposure to the child. We characterized radiation exposure from videourodynamics.Materials and Methods: We reviewed all recent videourodynamic studies and recorded patient demographics, urological diagnoses, physical attributes, total fluoroscopy time, total radiation exposure in mGy, bladder capacity and the number of filling cycles performed. Multivariate linear regression was used to identify patient factors that independently influenced total radiation exposure.Results: A total of 64 videourodynamic studies were performed in 34 female and 28 male patients with a mean age of 8.6 years (95% CI 7.2–10.0). The most common diagnosis was neurogenic bladder in 40 patients, although 49 had multiple diagnoses. Mean tot...
