Insights
Accessory nipples (AN) in children are not linked to urinary tract anomalies. This study found no evidence of malformations, suggesting no further investigation is needed for isolated cases of accessory nipples.
Area of Science:
- Pediatric Medicine
- Clinical Genetics
- Urology
Background:
- Accessory nipples (AN) are a common congenital finding.
- Previous studies have suggested a possible association between AN and genitourinary anomalies.
- The clinical significance of AN in children requires further clarification.
Purpose of the Study:
- To investigate the association between accessory nipples (AN) and urinary tract anomalies in pediatric patients.
- To identify potential risk factors for urinary tract malformations in children with AN.
Main Methods:
- A cohort of 102 infants and children with AN was studied.
- Data collected included ethnic origin, sex, family history of AN, and AN characteristics (number, site, shape).
- All participants underwent physical examination and abdominal ultrasound to screen for urinary tract malformations.
Main Results:
- No urinary tract malformations were detected in any of the 102 children studied.
- No correlation was found between AN and anomalies of the urinary tract.
- Factors such as ethnic origin, sex, family history, and AN characteristics did not predict urinary tract anomalies.
Conclusions:
- Accessory nipples (AN) in children are not associated with urinary tract malformations.
- Routine investigation for urinary tract anomalies is not warranted in children presenting with solitary AN.
- This finding simplifies clinical management and reduces unnecessary diagnostic procedures.
Abstract:
One hundred two infants and children age 3 days to 16.5 years, found to have accessory nipples (AN), were enrolled in this study. They were categorized by ethnic origin, sex, positive family history of AN, and number, site, and shape of AN, to determine factors for increased risk of anomalies of the urinary tract. Physical and ultrasound examinations of the abdomen did not reveal evidence of urinary tract malformation in any of the children. The results of this survey support the contentions that AN are not associated with urinary tract malformations, and that no further investigation is required in children with solitary AN.
