Two laterally based scrotal pedicled flap grafts in the treatment of penile skin necrosis due to ring incarceration: a case series

Abstract

Introduction The rise in the incidence of penile ring incarceration has led to additional cases of ischemic necrosis of the penile skin. Two laterally based scrotal pedicled flaps (LSPFs), noted for their rich blood flow and skin source, resemble penile skin and are the preferred donor sites for repairing such necrosis. Aims This study summarizes the outcomes of 2 LSPF grafts for the treatment of penile skin necrosis. Methods Data were collected from 5 patients with penile skin necrosis due to ring incarceration who sought treatment at Ankang Central Hospital between 2012 and 2023. Results All patients exhibited varying degrees of necrosis in the urethral corpus cavernosum and the penis’s anterior tip. Two LSPFs were used for wound repair, with direct suturing of the donor site. None of the 5 patients experienced flap necrosis postsurgery, and they regained normal urination function. The patients reported satisfaction with both the aesthetic and functional results. Conclusion Two LSPF grafts are an effective approach for repairing penile skin defects. They reliably cover necrotic penile skin defects, prevent further wound progression, preserve penile structure, and improve patients’ life quality.
