Introduction: To investigate if potty training from infancy can affect bladder dysfunction in
boys with posterior urethral valves (PUV). Subjects and Methods: The voiding pattern and emptying
ability were followed using the 4-hour voiding observation method in 17
Vietnamese boys with PUV aged 3 months to 4 years who had been potty-trained
from infancy. This group was compared with a group of healthy Vietnamese boys. Results: In the boys with PUV,
the bladder volume increased according to age, and interrupted voiding was
rare. However, when comparing boys with PUV with healthy boys, a significant
difference was noted with more frequent voidings and lower voided volumes in
the age group 0 - 1 year (P < 0.001). Despite the minimum amount of residual
urine, average 8 ml or less in the boys with PUV, the age groups 1 - 2 and 2 - 4
years had significantly higher residual volumes compared with those of the healthy
boys (P < 0.001). Conclusion: The
findings from the 4-hour voiding observation showed few signs of
dysfunctional bladder in the Vietnamese boys with PUV, including residual
urine, even if there were signs of dysfunction compared with the healthy Vietnamese
boys. Potty training from infancy could favor early bladder rehabilitation in
boys with PUV.
