Mean values for voltage kV and load mAs obtained in the examinations were 72 kV and 6.

In a review of similar studies in developed in other countries, one can better evaluate such difference. However, considering what occurred in the fluoroscopy study, where similar equipment presented very different cistouretrografa, leading to the finding of a serious problem in one of them which led to its deactivation, one may question if some technical non-conformity might be happening, and thus justify the high doses observed in the present study.

One of these units produced a DAP five times higher than the other and 4, cGy. The authors’ findings allow them to suggest that both DAP and ESD are good parameters to evaluate appropriate dose levels for voiding cystourethrography.

Paediatric x-ray examinations in Rio de Janeiro. The authors propose a greater awareness of radiologists, towards utilizing high kilovoltage techniques and reduced fluoroscopy time in the examination. View forum View forum without registering on UserVoice. Voiding cystourethrography is considered the standard method in the evaluation of vesicoureteral reflux and malformations of the urethra and bladder 4. The dose delivered by a determined radiological examination reaches its maximum on the surface of the irradiated area.


The use of ionizing radiation for diagnosis and therapy of pediatric patients has become a common practice with unquestionable benefits.

In an important Brazilian Institution of pediatric radiology, the doses are above those found in similar studies. The prevalence of a relevant pathology identified in children with VUR and normal renal ultrasonography was similar with both guidelines.

Automatic update in The utilization of high-kilovoltage and low-milliampere techniques, as well as fluoroscopy only for positioning the patient and observing the most remarkable alterations, will certainly cistouertrografia in an important dose reduction. Evaluation of radiation dose in voiding cystourethrography in children.

The main indications for this imaging method are: Ward 20 also suggests that, previously to the examination, the radiologist should obtain the clinical history of the patient and confirm if the indication is correct, or if some other method, such as radionuclide cystogram for example, might be a better indication to clarify the doubts of the assisting physician.

This demonstrates the need for a rigorous quality control in radiological equipment cisstouretrografia medical applications, especially in a pediatric hospital. The adoption of radiography with high kilovoltage technique and restricted utilization of fluoroscopy can result in a significant reduction of doses during this procedure, considering that the major contribution to the final dose comes from fluoroscopy.

The patients were divided into four age groups: The observation of total ESD ranging from 17 to We conducted a retrospective analysis of patients with UTI, aged between 2 and 24 months old, seen at our cistouretrkgrafia between January and August and who had a normal renal ultrasonography and VUR. Considering that the fluoroscopy time ranged from 82 to 1, seconds mean, secondsthe authors can suggest a radical reduction of this time.

Most recent studies 19,20 approach the utilization of technically more updated equipment, with the so called pulsed fluoroscopy, which considerably reduces the total dose, by directly influencing the fluoroscopy dose reduction.
