Pediatric urogenital tract foreign bodies (FBs) pose a management challenge, with increasing cases noted. Differentiating treatment based on FB location and patient age is crucial for minimizing complications.
Area of Science:
- Pediatric Urology
- Urogenital Tract Foreign Bodies
- Pediatric Surgery
Background:
- Urogenital tract foreign bodies (FBs) are rarely reported in children, presenting unique management challenges.
- A 10-year retrospective review was conducted to analyze the experience with pediatric urogenital tract FBs.
Purpose of the Study:
- To review a decade of experience with pediatric urogenital tract foreign bodies at a single institution.
- To analyze demographic characteristics, symptoms, diagnostic methods, and management strategies.
Main Methods:
- Retrospective review of medical records for children suspected of having urogenital tract FBs.
- Comparison of surgical strategies based on FB location and patient age.
- Analysis of FB location distribution across different age groups.
Main Results:
- 188 cases of urogenital tract FBs confirmed out of 239 suspected cases (150 girls, 38 boys).
- Increasing incidence over 10 years, with seasonal peaks in spring/summer; peak ages at 3-5 and 9-13 years.
- Vaginal FBs often managed with day surgery, while bladder FBs required inpatient care; age and sex influenced FB location.
Conclusions:
- Pediatric urogenital tract FBs present significant challenges, requiring tailored surgical approaches.
- Misdiagnosis can occur due to concealed insertion history or co-existing conditions; ultrasonography aids diagnosis.
- Preventive measures like appropriate toy selection and sex education are important; specialized techniques minimize complications, especially for migrated or magnetic FBs.
