title: Moderate agreement between bladder capacity assessed by frequency volume charts and uroflowmetry, in adolescent and adult enuresis patients.
abstract: Frequency Volume Charts (FVC) are recommended for the evaluation of enuretic patients. Although this is a good instrument for the assessment of functional bladder capacity, it is known that patient compliance could introduce problems. Therefore, we assessed whether uroflowmetry and post-void residual volume could replace FVC recordings in specific cases, by comparing the bladder capacity as measured by FVC or uroflowmetry.
  
  
  
  We performed post-hoc analyses using data from a retrospective cohort study, in secondary/tertiary care. This included 907 patients between 2003 and 2013, aged ≥11 years, suffering from enuresis (≥1 wet night/fortnight). Data were collected from the medical files. Bland Altman plots were made to compare the two methods.
  
  
  
  Agreement between uroflowmetry and FVC was reasonable only when uroflowmetry was between 200 and 450 ml.
  
  
  
  For individual clinical purposes, uroflowmetry can be used if values are in this range. For future research, we recommend to keep measuring bladder capacity with an FVC. Neurourol. Urodynam. 36:745-747, 2017. © 2016 Wiley Periodicals, Inc.
