Enxerto em U invertido para hipospádia
A technique developed by Prof. Dr. Ubirajara Barroso Jr. for complex hypospadias reconstruction, using a graft in an inverted U configuration as part of surgical planning.
The approach was designed for situations in which reconstruction requires better graft distribution and adaptation to the surgical bed, particularly in more complex cases or staged reconstruction.

What is enxerto em U invertido
A grafting technique used in the reconstruction of complex hypospadias.
Hypospadias is a condition in which the urethral opening is in a different position from usual and may be associated with anatomical changes of varying degrees.
In more complex cases, reconstruction may require grafts and possibly more than one surgical stage.
The inverted U technique arranges the graft in a specific way to aid adaptation to the reconstructive field and reduce limitations related to graft shape and tissue contraction.
How the technique is used
Planning starts with assessment of local anatomy, tissue quality and the extent of reconstruction required.
The graft is positioned in an inverted U shape, allowing graft tissue to be distributed more broadly over the area to be reconstructed.
Graft configuration
The inverted U design allows the tissue to be adapted to the anatomy and extent of the treated area.
Staged reconstruction
The technique may be used where reconstruction is planned over more than one surgical stage.
Integration with the surgical bed
The graft's position and shape are defined according to local conditions and the chosen reconstructive strategy.
When the technique may be considered
The indication depends on the complexity of hypospadias and each patient's anatomical characteristics.
Factors considered during planning include:
- Location and extent of the urethral change
- Quality of available tissues
- Associated curvature
- Previous surgery
- Scars and recipient bed conditions
- Need for reconstruction in one or more stages
The choice of enxerto em U invertido forms part of a broader reconstructive plan and does not represent an automatic indication for every hypospadias case.
Reconstruction adapted to anatomy
Treatment of complex hypospadias requires individualized assessment.
The decision on graft type, positioning and the number of reconstructive stages depends on anatomy, tissue availability and previous procedures.
Planning aims to create suitable conditions for urethral and genital reconstruction while respecting each case's anatomical limitations.
The technique should be understood as part of an individualized reconstructive strategy, rather than a single procedure that can be applied uniformly.
Risks, limitations and follow-up
As with other reconstructive surgery for hypospadias, complications may involve graft integration, healing, fistula formation, urethral narrowing, tissue contraction and the need for additional procedures.
Progress depends on case complexity, tissue quality and the patient's surgical history.
Results vary individually, and postoperative follow-up is part of the reconstructive process.
