What is already known about this topic? Lower urinary tract obstruction is associated with high morbidity and mortality. Fetal cystoscopy may allow the correct identification of the etiology of the obstruction and may provide the adequate treatment. What does this study add? Three‐dimensional virtual navigation is a noninvasive approach that provides an immersive virtual reality in the assessment of fetal structures. Three‐dimensional virtual cystoscopy provides a noninvasive evaluation of fetal lower urinary tract obstruction that in the future may help in the selection of candidates for fetal cystoscopy.
