Overview
Labial exostosis, often referred to in context with fused labia, involves the abnormal fusion or outgrowth of labial tissues, potentially leading to urinary tract symptoms such as suspected urinary infections and abnormal contrast material reflux during imaging. 1Diagnosis
Clinical Presentation: Asymptomatic in some cases, others present with urinary infection suspicion.
Key Diagnostic Tests: Micturating cystourethrography revealing contrast material collection above the labia and vaginal reflux.
Diagnostic Confirmation: Separation of labia resolves cystourethrographic abnormalities noted.
Initial Recognition: Radiologists may first identify labial fusion during catheterization in pediatric patients. 1Management
Surgical Intervention: Separation of fused labia is indicated to resolve symptoms and imaging abnormalities. 1
Post-Procedure Monitoring: Follow-up imaging to confirm resolution of reflux and anatomical correction.Special Populations
Pediatrics: Early recognition and intervention crucial, often identified during routine catheterization. 1Key Recommendations
Perform micturating cystourethrography in suspected cases of labial fusion to identify characteristic reflux patterns (Evidence: Moderate) 1
Consider surgical separation of fused labia to alleviate symptoms and correct anatomical abnormalities (Evidence: Weak) 1
Regular follow-up imaging post-separation to ensure resolution of urinary reflux and anatomical correction (Evidence: Expert opinion) 1References
