Uroflowmetry in Non-Monosymptomatic Nocturnal Enuresis in Children of Coastal Region of Croatia.

Purpose: The aim of the study was to describe clinical characteristics and bladder assessment in children with Non-Monosymptomatic Nocturnal Enuresis (NMNE) in coastal region of Croatia.

Materials and methods: Records on 85 patients with NMNE were retrospectively reviewed. Bladder assessments were performed in all children. In this research we: (i) compare clinical characteristics and features of bladder assessment: uroflowmetry, post void residuals (PVR) and bladder wall thickness between boys and girls with NMNE and we compare (ii) clinical characteristics and bladder assessment between children with primary and secondary NMNE.

Results: There were 46 girls and 39 boys. The total of 59 children had primary NMNE and 26 children had secondary NMNE. Uroflow pattern was abnormal in 42% of all children with NMNE. Abnormal uroflow pattern in children with NMNE was more often in girls than in boys (P < 0.05) and in children with secondary than in children with primary NMNE (P < 0.05). Ultrasound evidence of bladder wall thickness was more frequent in boys than in girls. Girls were more likely to have dysfunctional voiding and larger residual urinary volume than boys.

Conclusions: Abnormal uroflow pattern in children with NMNE was more often in girls than boys and in children with secondary than in children with primary NMNE.
