Development and validation of a bladder trabeculation grading system in pediatric neurogenic bladder.

Bladder trabeculation (BT) is commonly noted on cystogram images of patients with neurogenic bladder (NB). BT is associated with a hostile bladder often requiring prompt, more aggressive management. We aimed to define and validate a reliable grading system for BT severity. The proposed grading system will improve clinicians and radiologist's communication and serve as a foundation for future studies in the field of NB.
