To evaluate the clinical efficacy, safety, and three-month durability of negative-pressure therapy (NPT) as a non-surgical salvage intervention for pediatric patients with postoperative recurrent concealed penis.
Approach:
Key Findings:
Significant morphometric gains were achieved across all dimensions (all P < 0.001).
VPL increased by a mean of 0.76 cm (95% CI: 0.68 to 0.84), demonstrating a substantial clinical effect (Cohen's dz = 1.64).
Anatomical gains in FPL, SPL, and diameter were maintained at 3 months with no significant regression (P > 0.05).
Advanced chronological age, higher body mass index, and smaller baseline dimensions were independent predictors of superior anatomical improvement.
The protocol was well tolerated with no serious adverse events.
Interpretation:
NPT is an effective, non-invasive salvage strategy for pediatric recurrent concealed penis, providing stable anatomical expansion through mechanotransduction and serving as an alternative to complex re-operation.
Limitations:
Retrospective design may introduce selection bias.
Lack of a control group limits comparison of outcomes, potentially affecting the validity of the findings.
Conclusion:
NPT offers a viable non-surgical option for managing recurrent concealed penis in children, particularly for those with specific anthropometric characteristics.
