[The characteristics of the bladder-sphincter reflex in children].

Based on the examination of 89 children (71 patients with various bladder diseases and 18 healthy subjects), the authors developed a new procedure for recording the vesicosphincteral reflex by the use of urethral profilometry. The procedure involved comparison of background and stimulation examination findings of urethral profilograms. The optimum parameters were defined for detection of vesicosphincteral reflex and the conditions were developed for its performance. The procedure may be useful in the diagnosis of neurogenic bladder, sphincter-detrusor dyssynergia, stress-induced enuresis, etc.
