Abstract:
Objective
To investigate the effect of age on the incidence of urinary fistula after hypospadias Duckett.
Methods
A total 68 children were included of as the study subjects, who were admitted to the urinary. Surgery Department of Hunan Children's Hospital and received hypospadias Duckett from May 30,2013 to Nov. 30,2016.Observe the length of urethral absence and the incidence of urinary fistula in these children of different ages.
Results
Comparing the length of urethral absence among the children of different ages, there was no statistical difference(P>0.05). The incidence rate of urinary fistula in children under 6 years was 41.67%(10/24), which was significantly higher than that in children between 1 to 3 years(4.55%,1/22) and between 3 to 6 years(4.55%，1/22),the difference being statistical significance(P<0.017).
Conclusion
Age has some influence on urinary fistula after hypospadias Duckett, and the influence is greater with the increase of age. Therefore, the treatment for the fistula should be based on different ages in order to reduce the incidence rate, which will result in better treatment effects and improvement of these children's life quality.
