CONCLUSIONS
Bladder function in PUV is abnormal from childhood to puberty with no significant change in the
proportion of patients related to capacity, LUTS, need for treatment and uroflow.

PURPOSE
Bladder capacity (BC) in PUV may be abnormal; we studied whether BC is associated with incom-
plete emptying or impaired renal function.
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).
