cistouretrografía miccional con TV
In one of the patients included in this age group, fluoroscopy accounted for A comparison of doses and techniques between specialist and non-specialist centres in the diagnostic X-ray imaging of children. Radiation doses to paediatric patients undergoing micturating cystourethrography examinations and potential reduction by radiation protection optimization.
You can request verification for native languages by completing a simple application that takes only a couple of minutes. It is important to observe that the radiologist A performed the highest number and percentage of abnormal studies. The utilization of cishouretrografia and low-milliampere techniques, as well as fluoroscopy only for positioning the patient and observing the most remarkable alterations, will certainly result in an important dose reduction.
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.
Ward 20 also suggests ciistouretrografia, 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.
Inthe American Academy of Pediatrics AAP recommended perform a renal ultrasonography and avoiding cystourethrography to all infants between 2 and 24 months of age after their first urinary tract infection UTI.
The routine for examination starts with an abdominal radiograph in cisyouretrografia projection, with the patient in dorsal decubitus. Paediatric x-ray examinations in Rio de Janeiro. Dose-area product values in frequently performed complex paediatric radiology examinations. One half the children were one year cistourerrografia or less at the time the examinations were performed.
One can determine the radiation dose incident on the exposed areas by using the Diamentor, a device that is coupled to the x-ray tube that allows the monitoring of accumulative radiation emitted by the x-ray tube during the examination, and which will not interfere on the procedure performance.
The radiographs in the full filling stage should comprise the entire presumable urinary tract. This hospital is a reference in neonatology, pediatric surgery and medical genetics; consequently, the number of patients with congenital abnormalities is very high, with frequent cases of urinary abnormalities. It was found that the equipment makes divisions only “in the vertical sense”, meaning that one 30 x 40 film will always have images with 30 or 40 cm in height, if the manual collimation is not made, which increases the exposed area.
However, considering what occurred in the fluoroscopy study, where similar equipment presented very different doses, 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.
This demonstrates the need for a rigorous quality control in radiological equipment for medical applications, especially in a pediatric hospital. Voiding cystourethrography is considered the standard method in the evaluation of vesicoureteral reflux and malformations of the urethra and bladder 4. Post Your ideas for ProZ. Review native language verification applications submitted by your peers. The authors propose a greater awareness of radiologists, towards utilizing high kilovoltage techniques and reduced fluoroscopy time in the examination.
Total DAP ranged from to 1, cGy. On the other hand, Ruiz et al.
cistouretrografía miccional con TV | Spanish to English | Medical: Health Care
However, even being such use justifiable by the benefits to patients, standards and radioprotection techniques cannot be forgotten. Automatic update in Mean total DAP for radiography and fluoroscopy was separately evaluated for each age group, noticing that in the highest age group, the utilization of larger films and fluoroscopy cistouretrorafia contributes for a larger irradiated area, and consequently, to an increase in the dose Table 3.
In the present study, one of the factors that contributed for the magnitude of entrance skin doses was the lack of uniformity of the radiographic imaging techniques employed. Which is the best way of performing a micturating cystourethrogram in children? Radiation dose measurement and risk estimation for paediatric patients undergoing micturating cysto-urethrography.
The prevalence of a relevant pathology identified in children with VUR and normal renal ultrasonography was similar with both guidelines. Evaluation of radiation dose in voiding cystourethrography in children. Term search All of ProZ. For being anatomically related with the genital area where the ovaries that cannot be protected and testicles that can be partially protected from the inherent high examination dose by means of gonad protectorsthis imaging method causes a great exposure of these structures that are so sensitive to radiation.
Return to KudoZ list. Considering that the fluoroscopy time ranged from 82 to 1, seconds mean, secondscistouretrografai authors can suggest a radical reduction of this time.
Pediatric radiation exposure and effective dose reduction during voiding cystourethrography. You have native languages that can be verified You can request verification for native languages by completing a simple application that takes only a couple of minutes. The use of ionizing radiation for diagnosis and therapy of pediatric patients has become a common practice with unquestionable benefits.
The next step is a careful genital antisepsis and introduction of a catheter through the urethra to the interior of the bladder. 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.

English PRO mjccional in category: Patient dose reduction during voiding cystourethrography. On average, 11 radiographies are performed for each study, with extended fluoroscopy time delivering a higher average final dose than those reported in the literature.

This fact can be explained by the abnormal studies, which require additional incidences to adequately document alterations in the urinary tract such as, for example, the presence of bladder diverticula, male urethral abnormalities and other more complex abnormalities.
This means that all patients must receive the maximum attention in order to minimize the possibility of acute and late biological effects resulting from radiation exposure. Procedures performed in cistouretrohrafia patients by four physicians of the institution were evaluated. One even questioned if there might be an expressive difference in the biometric profile among the children, however, the BMI evaluation showed that the majority of them were low-weight children.
Assessment of dosimetric quantities for patients undergoing X-ray examinations in a large public hospital in Brazil – a preliminary study. The limitation of the fluoroscopy area only to the area of interest, even in equipment with automatic collimation as a function of the programmed film division, could be an additional dose reducing factor in these higher patients. Login cistouretrogrsfia register free and only takes a few minutes to participate in this question.
The dose delivered by a determined radiological examination reaches its maximum on the surface of the irradiated area. We conducted a retrospective analysis of patients with UTI, aged between 2 and 24 months old, seen at our department between January and August and who had a normal renal ultrasonography and VUR.
