Keywords: | children; lower urinary tract dysfunction; nomogram; post-void residual urine; urinary tract infection | Issue Date: | 2013 | Journal Volume: | 32 | Journal Issue: | 7 | Start page/Pages: | 1014-1018 | Source: | Neurourology and Urodynamics | Abstract: | Purpose To establish the first age- and gender-specific nomograms for single and two consecutive tests for post-void residual urine (PVR). Material and Methods Healthy children aged 4-12 years were enrolled for two sets of uroflowmetry and PVR. The first PVR and the lower value of the two consecutive PVRs of each child with a voided volume ?50 ml were included for construction of Single- and Dual-PVR nomograms. Children with possible urinary tract infection or lower urinary tract dysfunctions were excluded. Results and Limitations Totally, 1,128 children (583 boys and 545 girls) with a mean age of 7.7 ± 2.2 years were eligible for analysis. The 95th percentile of Single-PVR for all children was 27.2 ml, or 19.2% of bladder capacity (BC), while that for Dual-PVR were 11.2 ml or 6.0% of BC, respectively. Multivariate studies showed that PVR was positively associated with BC, negatively associated with age, higher in boys than girls, and higher in abnormal uroflow patterns. For children aged ?6 years, a single PVR >30 ml or >21% BC, or repetitive PVR >20 ml or >10% BC can be regarded as elevated. For children aged ?7 years, a single PVR >20 ml or 15% BC, or repetitive PVR >10 ml or 6% BC can be redefined as elevated. Conclusions Age, gender, and BC should be taken into considerations at interpretation of PVR tests in children. Repeating PVR test is recommended when a single PVR is higher than the 95th percentile of age- and gender-specific PVR. Neurourol. Urodynam. 32: 1014-1018, 2013. ? 2013 Wiley Periodicals, Inc.
