Abstract

Hypothesis / aims of study
To investigate the correlation and difference between the incidence of urinary tract infection (UTI) and redundant prepuce in urban and rural adolescents, so as to provide reference for the prevention and treatment of UTI in adolescents.
Study design, materials and methods
During the period from September 2018 to October 2019, using the opportunity of freshmen's physical examination at the beginning of school, we selected college students from all over the country to investigate the correlation between redundant prepuce and UTI.This survey used anonymous questionnaires to collect relevant information. A total of 3800 questionnaires were sent out and 3702 valid questionnaires were collected, including 1347 urban teenagers and 2355 rural teenagers. Compared the collected data with the physical examination information, and analyzed the reliability of the questionnaire. The data were divided into urban and rural groups, and the incidence and related factors of redundant prepuce and UTI in each group were compared.The related factors include birth date, birth place, height, weight, whether phimosis and redundant prepuce, situation of wash up prepuce , whether prepuce operation, whether adhesion of prepuce, smegma, UTI, and so on. Finally, SPSS21.0 statistical software was used for correlation analysis.
Results
18.04% of urban teenagers is redundant prepuce, 28.34% of rural teenagers is redundant prepuce, 0.46% of urban teenagers is phimosis, 1.35% of rural teenagers is phimosis. The difference of UTI between urban adolescents with and without redundant prepuce is statistically significant(2=11.906, P<0.05); The difference of UTI between rural adolescents with and without redundant prepuce is statistically significant(2=10.303, P<0.05); The difference of UTI between urban adolescents with and without phimosis is statistically significant(2=8.344,P<0.05); The difference of UTI between rural adolescents with and without phimosis is statistically significant (2=4.782, P<0.05); there was a significant difference between urban and rural adolescents in whether they often wash their prepuce (2=123.085, P<0.05); There was no significant difference between urban and rural adolescents in the presence of smegma(2=1.959, p>0.05).
Interpretation of results
The prevalence rate of redundant prepuce is very high in Chinese adolescents, Urinary tract infection is closely related to redundant prepuce .According to the survey, there is a significant difference in the incidence rate of urinary tract infection between city and rural adolescents, which is obviously related to the area where they are, whether phimosis and redundant prepuce, situation of wash up prepuce , whether prepuce operation, whether adhesion of prepuce, smegma and so on.
Concluding message
Redundant prepuce and phimosis are significantly related to the incidence of UTI. The incidence of phimosis and redundant prepuce in rural adolescents is significantly higher than that in urban adolescents, which suggests that the difference between redundant prepuce and phimosis is one of the reasons. It also suggests that strengthening the propaganda and education of rural adolescents and correcting redundant prepuce and phimosis can reduce the incidence of UTI.
