Description
Summary:Background: The invasiveness and exposure to radiation in voiding cystourethrography led to the introduction of alternative methods of diagnosis of vesicoureteral reflux, including contrast enhanced voiding urosonography. While there is a limited number of studies comparing these methods using new generation ultrasound contrast agents, none of them compared both methods simultaneously. This study is aimed at assessing agreement between contrast enhanced voiding urosonography with second-generation ultrasound contrast agents and voiding cystourethrography. Methods: From April 2013 to May 2014, 83 children (37 female and 46 male), mean age 3.5 years, age range from 1 month to 17.5 years, underwent prospective simultaneous assessment by contrast enhanced voiding urosonography and voiding cystourethrography, with a total of 166 uretero-renal units evaluated. Results: The sensitivity of voiding cystourethrography and contrast enhanced voiding urosonography were comparable, amounting to 88%, however, neither reached 100% for the entire studied population. The negative predictive value of voiding urosonography and voiding cystoureth-rography was 97%, and there was no difference between both methods. Conclusion: Voiding cystourethrography and contrast enhanced voiding urosonography are comparable methods in diagnosis of vesicoureteral reflux, and can be performed alternatively. However, some limitations of contrast enhanced voiding urosonography must be remembered. Key words vesicoureteral reflux, voiding cystourethrography, voiding urosonography, ultrasound contrast agent, SonoVue Wprowadzenie: Negatywne skutki promieniowania jonizujacego wykorzystywanego do badan cystouretrografii mikcyjnej wymuszaja poszukiwanie alternatywnych metod diagnostycznych. Takim badaniem moze byc sonocystografia mikcyjna z uzyciem ultrasonograficznych srodków kontrastujacych. Liczba prac porównujacych klasyczne badanie cystouretrografii mikcyjnej i badanie ultrasonograficzne z uzyciem srodków kontrastujacych drugiej generacji jest jednak niewielka. Dotad nie opublikowano pracy, która porównalaby jednoczasowo obie metody w diagnostyce odplywów pecherzowo-moczowodowych. Prezentowana praca ma na celu ocene zgodnosci miedzy badaniem ultrasonograficznym z uzyciem srodków kontrastujacych drugiej generacji i badaniem cystouretrografii mikcyjnej. Material i metody: W okresie od kwietnia 2013 do maja 2014 roku jednoczasowe badanie ultrasonograficzne z uzyciem srodków kontrastujacych drugiej ge
