Place de la cystomanométrie à colonne d’eau dans l’exploration des vessies neurologiques chez l’enfant

Abstract

IntroductionDescribe the technique of water column cystometry in children and investigate the existence of a correlation between the leak point pressure measured by this process and the alteration of the upper urinary tract. Subjects and methodsDuring the period 2009 - 2012, 48 children with neurogenic bladder secondary to myelodysplasia, aged between 2 and 15 years at the first consultation and have not received a specific medical treatment for bladder sphincter dysfunction or surgery on the urinary tract, have been explored by a clinical examination, ultrasound of the urinary tract, retrograde urethral-cystography and a water column cystomanometry without using a device of urodynamic study. ResultsThe average age of the series was 6 years old. The upper urinary tract dilatation was present in 30 cases and vesicoureteral reflux in 22 cases. Of all the 28 cases that had a leak point pressure> 40cm of water dilatation of the upper urinary tract was present in 24 cases and vesicoureteral reflux in 19 cases. DiscussionThe results obtained show that there is a correlation between the elevation of the leak point pressure above 40cm of water and alteration of the upper urinary tract. They are similar to those found in the literature. ConclusionThis study shows that the water column cystometry is an effective alternative that provides a reliable measure of the leak point pressure.
