MATERIAL AND METHODS Retrospective cross-sectional review of non-invasive urodynamics at the age of 5, 10 and 15 years in boys with PUV. Data recorded: Bladder capacity (BC) classified as large, normal and small as per ICCS criteria1; percentage ratio for BC and expected BC (EBC); post-void residuals (PVR); iohexol GFR. Patients divided into 3 groups according to their age. Statistical tests performed within each group (p statistically significant <0.01): Chi Square to evaluate BC and incomplete emptying. Pearson to compare voided volume (VV) and PVR Pearson to compare BC/EBC% and GFR. RESULTS We identified studies from 133 children between 2008–2017; patients with renal transplant (n = 25) and bladder augmentation (n = 13) were excluded. There is no statistically significant correlation between incomplete bladder emptying and BC in the three age groups (although there appears to be a trend); p=0.10, p=0.08, p=0.05. VV is not related to PVR: p=0.30 (group 1), p=0.66 (group 2), p=0.48 (group 3). Furthermore BC does not predict renal impairment: p=0.28 (group 1); p=0.64 (group 2); p=0.31 (group 3).
