Primary hypospadias repair techniques: A review of the evidence

This review summarizes data regarding commonly used surgical techniques to repair distal and proximal hypospadias. We review evidence concerning indications for various procedures used in primary hypospadias repair, and their complications, urinary function and esthetic results. Available evidence suggests TIP is preferable to Mathieu for distal hypospadias correction. Current data do not identify a clear preference between TIP and onlay flap for proximal repair when there is ventral curvature 31°. A review of objective data helps clarify decision-making for distal hypospadias repair. Additional objective evidence is needed to identify preferred options for proximal hypospadias repair. Measuring glansplasty dimensions (meatal size and distance from meatus to corona) may improve urinary function assessments, and provide additional objective data for decision-making between various surgical techniques.
