AB To the Editor.— 
    In the QUESTIONS AND ANSWERS section of The Journal (240:1281, 1978), Fletcher C. Derrick, Jr, MD, replies to O. G. Kauder, MD, with regard to a suspected neurogenic bladder. While his recommendations for a cystometrogram seem most appropriate, I think in addition to this a myelogram would be desirable, and this was not mentioned.In the past eight or ten years I have seen six or seven patients with neurogenic bladders from an obscure cause, some of them of a number of years' duration, in which myelography has revealed a central disk protrusion at L-4 or L-5, more commonly the latter. With laminectomy and disk removal giving nerve root decompression, satisfactory bladder function has returned in most cases.The one case that I recollect in which this failed to happen was in a person who also had multiple sclerosis, so that disk protrusion cannot be altogether indicted
