Objective: To evaluate the role of bladder volume and bladder wall thickness measurement by ultrasound in assessing severity and predicting response to behavioral therapy in children with monosymptomatic nocturnal enuresis.

Methods: 122 children (68 boys and 54 girls) aged 5-9 years underwent ultrasound evaluation of bladder volume and bladder wall thickness, followed by calculation of the bladder volume wall thickness index (BVWI). They were treated using first-line management (behavioral therapy) for 4 months.
