Introduction:

Boys affected by PUV may develop bladder dysfunction. We aimed to evaluate bladder status at 10 years of age.

Material and methods:

We retrospectively reviewed non-invasive urodynamics performed at ten years in PUV patients. Data recorded: Bladder capacity (BC) and expected BC (EBC), post- void residual (PVR), uroflow pattern, lower urinary tract symptoms (LUTS) and current bladder. Patients divided in group 1 - large BC (>150%EBC), group 2 - normal BC and group 3 - small BC (<65% EBC) as per ICCS criteria. Incomplete bladder emptying was considered when >10% of BC.

Results:

We identified 84 boys born 1997 - 2006; we excluded those who had bladder augmentation (n=7), renal transplant (n=12) or had unavailable information (n=11). 54 patients were analysed (outcomes shown in table). Three patients practised CIC (two in group 1, one in group 3). Two had recurrent UTIs (one in group 1 with abnormal PVR; one in group 3, normal PVR). Seven patients (13%) demonstrated normal uroflow assessment. See Table. 1

Conclusions:

At 10 years, the majority of boys with PUV (87%) have abnormal bladder function with 54% having incomplete bladder emptying.
