Moderate agreement between bladder capacity assessed by frequency volume charts and uroflowmetry, in adolescent and adult enuresis patients

Item does not contain fulltext AIMS: 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. METHODS: 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. RESULTS: Agreement between uroflowmetry and FVC was reasonable only when uroflowmetry was between 200 and 450 ml. CONCLUSIONS: 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.
