Radionuclide voiding cystography

Study of the ureters and bladder in pediatric nuclear medicine is limited to the use of radionuclide cystography for evlauation of suspected vesicoureteric reflux. Radionuclide cystography permits continuous monitoring of bladder filling and emptying. Reflux can be detected and its dynamics recorded at any and all times during the study. Using computerized gamma cameras, estimates of the capacity of bladder and the volume of reflux can be made. Simultaneous recording of intravesical pressure permits assessment of reflux dynamics and analysis of the relationship between intravesical volume, pressure, and reflux
