Videourodynamics (VUDS)

Abstract

Videourodynamic studies consist of the simultaneous measurement of multichannel urodynamic parameters with imaging (fluoroscopy) of the lower urinary tract. The technique is the most sophisticated investigation of lower urinary tract since it provides a precise evaluation of both anatomy and function. Fluoroscopy allows direct observation of the bladder outline, the position and conformation of the bladder neck in relation to the pubic symphysis, bladder neck closure during rest and stress, and vesicoureteric reflux during filling and voiding. Most of the equipments commercially available are provided with softwares that correlate fluoroscopic images with the corresponding urodynamic parameters such that reports have the images simultaneously with the pressure tracings.
