About this trial
Boys with posterior urethral valves have bladder dysfunction of varying severity. Early treatment of these children with anticholinergics is recommended by some teams, although there have never been any clear studies on the subject. To our knowledge, no comparative study of the evolution of valve bladders with or without treatment has been carried out to date.
Anticholinergic treatment, although it may be beneficial in patients with abnormal bladder function, such as the neurologic bladders ( in Spina Bifida) for example, may have side effects and may not be of benefit for this valve population. The evolution of the valves could be spontaneously favorable.
This study would be the first randomized clinical trial of early therapeutic drug intervention in the posterior urethral valve population.
