Evaluation of bladder capacity in pediatric patients with nocturnal enuresis using voiding diary and uroflowmetry: A retrospective study.

OBJECTIVE

This retrospective study was conducted in a tertiary hospital in Turkiye, it was aimed to evaluate the results of kidney and bladder ultrasonography, uroflowmetric study and volume frequency chart in children diagnosed with bedwetting at night.

METHODS

This study focused on patients aged 5-17 years who were treated for nocturnal enuresis in the single-center pediatric urology clinic of a tertiary hospital between 2017-2021. Patients' comorbidities, surgical history, urinary ultrasonography findings, uroflowmetry examination results, and two-day voiding diary were requested.

RESULTS

The number of pediatric patients diagnosed with enuresis nocturna was 956. Abnormal ultrasonography findings were observed in 13.9% of patients. Almost half of the patients had a positive family history, and 13.4% had a history of previous surgical procedures. While the voiding diary indicated that 54.2% of patients had bladder volumes equivalent to the expected bladder capacity, uroflowmetry examination revealed low bladder capacity in 65% of patients.

CONCLUSION

This study underscores the significance of comprehensive evaluations, including detailed ultrasonography and voiding diary measurements, in pediatric patients with monosymptomatic enuresis nocturna. Our study suggests that bladder volume measured through a two-day weekend voiding diary may provide more effective information for estimating optimal bladder capacity compared to measurements obtained through uroflowmetry.
