Comparison of meatal-based flap (Mathieu) and tubularized incised-plate (TIP) urethroplasties for primary distal hypospadias: A systematic review and meta-analysis

Systematic review comparing Mathieu and TIP urethroplasty techniques for distal hypospadias repair in 1,386 patients. Both techniques showed equivalent outcomes for fistula, dehiscence, and flap necrosis, but Mathieu demonstrated significantly lower meatal stenosis rates, particularly with modified technique and running suture approach.
