Studies of enuresis. IX. Evidence of a mild form of compensated detrusor hyperreflexia in enuretic children.

We studied 41 consecutive enuretic boys and girls by supine cystometry followed by a cystometrogram in the standing position. The micturition stop test was performed on 30 of the 41 patients. The standard cystometrogram proved to be superior to the supine study in detecting stage II (overt) detrusor hyperreflexia. Furthermore, the stop test effectively demonstrated the presence of stage I (compensated) hyperreflexia, a mild degree of detrusor unsubstantiated but assumed to be present in many children with simple enuresis. Stage I detrusor hyperreflexia may now be defined clinically by normal standing and supine cystometrograms, and a positive micturition stop test.
