title: [The urethrogram in children with neurogenic bladder dysfunction (author's transl)].
abstract: Various types of neurogenic bladder dysfunction in children show characteristic changes on micturating cystograms. The reflex bladder shows a short area of narrowing of the urethra at the pelvic floor; the autonomous bladder, during voiding by straining or Credé shows an elongated and deformed urethra, which is narrowed at the pelvic floor and which, because of the low position of the bladder, is angled. Both spastic and paretic pelvic floor in association with neurogenically determined abnormalities of bladder emptying may result in functional obstruction of the urethra. This, like any other stenosis, leads to morphological changes, first in the lower, but subsequently in the upper urinary tract. Children with neurogenic bladder dysfunction occasionally have micturating cystograms which resemble the appearances of urethral valves. The occurrence of so-called occult neurogenic bladders is mentioned and the difficulties in diagnosis associated with this condition are stressed.
