Objective: To study the clinical profile and to assess the Functional Bladder Capacity by ultrasonography and uroflowmetry in children presenting with Primary Monosymptomatic Nocturnal Enuresis.

Methods: An observational study was carried out in children (aged 5 -15 years) presenting to Pediatrics OPD between November 2018 to February 2020 with PMNE. Detailed history using a Clinical Management Tool, clinical examination, UTI investigation, Ultrasonography of KUB done. Also, Urodynamic Studies done. A 48-hour bladder diary provided to measure intake of fluids and frequency/ volume of urine.

Results: 46 children with mean age of 9.61 years were included. Boys were more affected than girls. Significantly associated factors were younger age, families with low income, family history of bedwetting, 37 patients (80.4%) had low functional bladder capacity. In 21 out of 26 children in whom UDS done showed normal in 21 children and abnormal only in 5 children. A weak correlation noted between maximal voided volume by bladder diary and voided volumes by UDS and FBC by ultrasound respectively.

Conclusion: PMNE is a multi-etiological disorder results from the interaction of genetics, sleep and psychological disturbances. History taking and bladder diary are sufficient for diagnosis but ultrasound and uroflowmetry to be done where facilities are available since abnormal UDS can be seen in PMNE cases too and low FBC noted.
