The voiding cystourethrography (VCUG) is a medical-radiological procedure used in suspected vesicoureteral reflux (VUR) or bladder / ureter abnormalities [1,2]. The procedure consists of a dynamic evaluation under fluoroscopic control with acquisition of X-ray images (Fig.1). The examination is subject to large variations of the total fluoroscopy time and the number of images. This variability is linked to factors attributable both to the patient (clinical history, conformation, level of cooperation) and to the operator's experience, and inevitably affects the dose to the organs. A valuable...

In light of this document, the level of optimization of the procedures performed in our IRCCS was evaluated, comparing the total DAP values ​​of the individual tests with those published in the PiDRL and assessing the dose to the organs and the effective dose related to the CUM. For the evaluation of the effective dose, the PCXMC simulation software (Fig.2), based on the Montecarlo calculation method, was used, which allows to obtain the dose values ​​for each organ and effective dose based on the technical...

The results obtained on the about 40 patients, are in an age range between 0 and 15 years old and are grouped in the following sub-groups: 16 patients of 0 year old, 11 patients of 1 year old, 3 patients of 5 year old , 3 patients of 10 year old, 4 patients of 15 year old. Obviously the number of pediatric patients, for this medical-radiological procedure, is most frequently performed in a range-age of 0-1years. The results show that the DAP values ​​obtained are...
