Purpose:
Frequency Volume Charts (FVC) and uroflowmetry are recommended for the evaluation of a child with nocturnal enuresis (NE).
The objective bladder capacity (BC) can be obtained by Frequency Volume Charts (FVC) and uroflowmetry (UFM). These modalities of assessment are recommended for the evaluation of a child with nocturnal enuresis (NE). The aim of the study was to evaluate the BC according to the treatment outcome in cohorts of children with NE.
Methods:
A total of 69 children (mean age 6.9 ± 1.9 years, 5-13 years) with NE were included in the study between July 2017 and February 2019. All patients filled out the questionnaire and 48-h FVC and UFM with ultrasound post-void residual assessment (PVR) completely. Our questionnaire included items on medical history and urinary symptoms (frequency, urgency, urge incontinence, and dysuria, so on). We analyzed information on lower urinary tract symptoms from the questionnaire. The response rate was analyzed at 3 months after standard urotherapy and medication.
Results
The percentage of children (42 male and 27 female) with complete response, partial response, and non-response at 3 months was 21.7% (15/69), 43.5% (30/69) and 34.8% (24/69), respectively. The mean FBC obtained from home 48-h FVC and UFM were 152.6 ± 74.6 ml and 127.3 ± 60.9 ml, respectively. Both mean FBC showed only 53.1 ± 22.7% and 45.9 ± 20.7% of expected BC ((age in years + 1) x 30), respectively. Moreover, there was no significant difference in FBC among 3 groups, the better response group showed a trend of the larger FBC. All parameters were no significant difference among 3 groups (p>0.05) except age (p=0.049).
Conclusions:
FBC was lower than expected BC in a child with NE. In this study, BC could not predict the treatment outcome of NE. A further larger study is needed to be verified. |
