Correct radiologic diagnosis of neurogenic bladder is mainly based on morphofunctional information derived from voiding cystourethrography. This examination allows the evaluation of the bladder morphology, the degree of filling, and the validity of muscular contraction. Indications on the bladder neck, striated sphincter function and urethral morphology are also provided. Presence of ureterovesical reflux is detected with its possible precise classification. Abnormal amount of residual urine is identified and often early diagnosis of most common complications of neurogenic bladder as vesical lithiasis, diverticula and infections, can be established.
