Summary

Preputial flora in uncircumcised boys changes with age, impacting urinary tract infection (UTI) risk. Younger boys harbor enteric bacteria, while older boys show more skin flora, affecting UTI development.

Area of Science:

  • Pediatrics
  • Microbiology
  • Urology

Background:

  • Urinary tract infections (UTIs) are common in children.
  • The preputial sac can harbor microorganisms, potentially leading to UTIs.
  • Understanding preputial flora composition is crucial for pediatric UTI prevention.

Purpose of the Study:

  • To investigate the presence and types of preputial flora in healthy, uncircumcised male children.
  • To analyze how preputial flora differs across distinct age groups (0-6 years vs. 7-12 years).
  • To correlate preputial flora changes with age and potential UTI risk factors.

Main Methods:

  • Simultaneous collection of preputial and urine samples from 92 uncircumcised boys aged 0-12 years.
  • Categorization of participants into two age groups: 6 years or younger (47 subjects) and 7-12 years (45 subjects).

  • Microbiological culture and analysis of preputial and urine samples, with statistical comparison between age groups.

    • Main Results:

    • Preputial cultures were negative in 27% of older boys (7-12 years) compared to 8% in younger boys (0-6 years) (P=0.02).
    • Enteric bacteria were predominant in younger children's preputial flora, whereas skin flora dominated in older children (P=0.002).
    • All urine samples remained sterile, indicating no active UTI at the time of sampling.

    Conclusions:

    • Preputial bacterial flora composition significantly changes with age in uncircumcised boys.
    • These age-related shifts in flora may be influenced by evolving immune status, anatomical changes, and hygiene practices.
    • Understanding these dynamics is key to managing and preventing pediatric UTIs.
