Cinefluorography of the urinary tract in childhood.

Most of the recent investigations of the lower urinary tract have been concentrated on the ureterovesical junction. Studies of 120 children examined by the method of voiding cinecystography and urethrography revealed that vesicoureteral reflux occurred in 22 cases without evidence of a lesion of the urethra, and in six children secondary to lesions of the urethra. Thirteen of the children studied had isolated lesions of the urethra. Urethral lesions encountered in this series of children included stenosis of the external meatus (14 cases), urethral valve (one case), urethral polyp (one case) and urethral stricture (two cases). The main advantages of cinefluorography and television control in this field lie in the fact that all phases of the voiding act can be observed and, when necessary, recorded on a movie film. Motion picture films provide visual evidence of the value of the method.
