Single-stage salvage urethroplasty for failed distal hypospadias: comparison of Mathieu and grafted tubularised incised plate repairs

Aim Distal hypospadias repair is a common operation but some children require a complete salvage operation due to major complications of initial repair. The aim of this paper is to analyze the results of single-stage salvage distal hypospadias operations with salvage Mathieu (SM) and salvage grafted tubularised incised plate (SGTIP) techniques. Patients and methods A retrospective review of 115 children from 2 centers who underwent SM or SGTIP operations for failed distal hypospadias from January 2012 to July 2021 was conducted for demographic data, success of salvage operation and complications. Children with scarred urethral plate but with healthy, mobile ventral skin underwent SM operation, while children with a supple urethral plate of width 6 mm or greater underwent SGTIP operation. Twenty-four (21%) children with pre-operative glans width
