title: Manometric and electromyographic assessment of urethral resistances in children.
abstract: In an attempt to define urethral resistances in children, 84 cystometries were performed, combined with an anal EMG in 54 cases. The urethral pressure profile was measured in each patient. The following parameters were studied: bladder tone, activity and contractility; micturition EMG; maximal urethral pressure; aspects of the urine stream; and residual urine. It was found that each parameter considered alone is insufficient for assessment of bladder outlet obstruction. Only the complete investigation proved to be highly reliable as a complement to radiological findings, and allowed a dynamic assessment of bladder and sphincter functions.
