Showing 1 Abstract.
In this exhibit, we will describe the synergistic effect of urodynamics and imaging. Bladder dysfunction, a common problem in children, accounts for up to 40 percent of pediatric urology clinic visits. Urodynamics is a key study to determine the etiology of bladder dysfunction yet, many radiologists are unfamiliar with this exam. Urodynamics is a fluoroscopic evaluation of the bladder with contrast during which abdominal and bladder pressures are measured while the bladder fills and empties. It uses a combination of electromyogram to evaluate pelvic floor contractions, cystometrogram to evaluate bladder pressures and capacity, and voiding cystourethrography to evaluate lower urinary tract anatomy. This exhibit will explain the indications for urodynamics, the basics of its interpretation including detrusor function and pressure flow studies, and the types of pathologies which may be diagnosed. Neurogenic bladder, congenital abnormalities, and how to differentiate between subsets of overactive bladder and underactive bladder will be explained. We will show imaging findings which correlate with these urodynamic diagnoses and describe ways to enhance voiding cystourethrograms and sonograms to better evaluate children with lower urinary tract dysfunction.
