Abnormal urodynamic findings in children with nocturnal enuresis.

Reduced nocturnal bladder capacity has been suggested in the pathogenesis of nocturnal enuresis. This study was conducted to define frequency of bladder dysfunction in enuretic children and determine parameters which might predict bladder dysfunction. 60 children were enrolled. Full urodynamic study (UDS) was done in case of abnormal uroflowmetry, abnormal bladder ultrasound, daytime incontinence and age 10 years. Of 60 patients ultrasound 48 underwent complete UDS. In 11, results of UDS were unreliable. The results were normal in 10 (20.8%) and 27 (56.2%) had abnormal UDS .The study revealed that abnormal UDS is common in enuretic children and overactive bladder is the most common findings. No clinical feature were found, which could identify children requiring UDS.
