Insights

The foreskin (prepuce) may harbor Proteus mirabilis, a common cause of urinary tract infections (UTIs). Uncircumcised boys showed significantly higher rates of this bacteria compared to circumcised boys, suggesting a link.

Area of Science:

  • Pediatric Urology
  • Microbiology
  • Infectious Diseases

Background:

  • Urinary tract infections (UTIs) are common in children.
  • Proteus mirabilis is a significant pathogen causing UTIs.
  • The role of the prepuce in harboring UTI-causing bacteria is not fully understood.

Purpose of the Study:

  • To investigate the association between the prepuce and Proteus mirabilis colonization.
  • To compare the prevalence of Proteus mirabilis in the periurethral area of circumcised and uncircumcised boys.

Main Methods:

  • Swabs were collected from the periurethral area and urethral meatus.
  • Cultures were performed on 124 uncircumcised and 60 circumcised boys.
  • Bacterial growth, specifically Proteus mirabilis, was identified and quantified.

Main Results:

  • Proteus mirabilis was isolated from 22.6% of uncircumcised boys.
  • Only 1.7% of circumcised boys yielded Proteus mirabilis in cultures.
  • A statistically significant difference in colonization rates was observed between the two groups.

Conclusions:

  • The prepuce may serve as a reservoir for Proteus mirabilis.
  • Circumcision may reduce the risk of Proteus mirabilis colonization in the periurethral area.
  • These findings suggest the prepuce is a potential source for Proteus-related UTIs in boys.
