Purpose: The complete history and physical examination with a specific focus on the genitourinary and neurologic systems, is generally sufficient to evaluate a patient with nocturnal enuresis. However, the measurement of uroflow and residual urine measurement should not usually be considered at the initial assessment. We prospectively assessed the usefulness of uroflowmetry and residual urine measurement in the children with nocturnal enuresis.
Materials and Methods: A total of 45 children with primary monosymptomatic nocturnal enuresis between January 2008 and July 2009 were randomized into 2 groups; experimental group I (n=32) and control group II (n=13). Uroflowmetry and residual urine measurement were performed in only group I. The flow curves were divided into 4 types; bell, plateau, fractionated and intermittent type. We evaluated treatment response 3 months after treatment. The treatment response defined as more than 50% reduction of the number of baseline wet nights.
Results: The mean age of group I and II were 7.8±1.9 and 7.6±2.3 years, respectively (p＞0.05). In normal uroflow curve (bell shape), mean voided volume and residual urine volume were 142.6±83.5 and 30.1±41.2 ml, respectively. In abnormal uroflow curve, mean voided volume and residual urine volume were 153.9±91.4 and 37.6±35.8 ml, respectively (p＞0.05). Abnormal uroflow curve of fractionated, intermittent and plateau were 4, 4 and 2 children, respectively. The treatment response of group I and II were not significantly different (71.8% vs 69.2%; p＞0.05). But, in group I, treatment response of normal curve and abnormal curve were significantly different (81.8% vs 50%; p=0.04).
Conclusions: The uroflow and residual urine measurement may be useful to predict a treatment response in the children with primary monosymptomatic nocturnal enuresis.
