Dartos island skin flap in 1-stage urethroplasty for complex posterior urethral obliteration / 中华泌尿外科杂志

ABSTRACT

Objective To report the experience in managing complex posterior urethral obliteration with dartos island skin flap. Methods 32 patients with complex posterior urethral obliteration were treated with dartos island skin flap substitution urethroplasty.Partial resection of the inferior pubic synphysis was needed to facilitate high proximal placement of the flap. Results The outcome was excellent in 31 (97%).Including subsequent procedures,the over all 3 months～7 years fllowup investigations were carried out in 27 patients.Urinary flow rates of more than 15 ml/s (for adults) and 8 ml (for children) could be achieved in 25 of 27 patients.Two patients with urinary flow decreased required further reconstruction.The hairy pouch formed within scrotal skin flap was noted in two patients. Conclusions Dartos island skin flap urethroplasty is a highly effective 1-stage method of reconstructing complex posterior urethral obliteration.
