Background

The percentage of sexual transmitted infection(STI) in adolescents had been underestimated and misdiagnosed as urinary tract infection(UTI), which may lead to unnecessary treatment and public health issue. We aimed to distinguish STIs through symptoms, laboratory and urinary analysis. We emphasize on the correlation of STIs and child maltreatment.

Methods

We performed a retrospective study of adolescents aged from 15-18 years old, who visited a tertiary center from January 1, 2015 through July 30, 2018, with diagnosis of urinary tract infection, acute cystitis, acute pyelonephritis, dysuria, urinary frequency, or renal colic. We compared clinical characters, symptoms, serum laboratory data, urine analysis, percentage of been reported to Social Affair Bureau between STIs and UTIs groups.

Results

Of the 45 adolescents, there was a significant difference in pyuria count(p=0.036), with 44.7% of UTI group reached the highest pyuria level (WBC>100/HPF) and none in STI group had pyuria >100/HPF. 71.4% of STIs had only mild pyuria with 5~49/HPF. No significant difference in clinical symptoms, including fever, dysuria, hematuria, abdominal pain, flank pain, serum white cell count, or CRP level between UTIs and STIs groups. We found 71% of adolescents with STIs had been reported as in need of child protection.

Conclusion

The clinical features and serum laboratory data were overlapping in STIs and UTIs, and both of them cause pyuria, which may lead to over-diagnosis of UTIs. Adolescents with lower degree of pyuria had higher possibility of STIs. The incidence of family dysfunction in STI is extremely high.
