Of 358 antegrade voiding urethrograms obtained in 200 males with spinal cord injury, the urethra was satisfactorily shown by 154 (77%), permitting evaluation of alterations related to cord damage, surgery, or iatrogenic trauma. In 105 cases the neurogenic urethra was normal, demonstrated only minor distension, or had a patulous appearance, in contrast to urinary tract changes such as a markedly neurogenic bladder, vesicoureteral reflux, and bladder calculi. In 49 patients, abnormalities included (a) changes related to surgical alleviation of sphincter dyssynergia; (b) iatrogenic changes such as diverticula, strictures, undermining of the external sphincter ('spiral sign'), and intravasation of contrast material; and (c) pressure necrosis of the urethra. Some changes need no special treatment; others, such as pressure necrosis, require early recognition and prompt therapy.
