Modified one-stage dorsal-inlay buccal mucosa graft technique for ventral penile urethral and penile skin erosion: A step-by-step guide

OBJECTIVE: To demonstrate the use of a modified single-stage technique for the repair of a ventral penile urethral erosion with involvement of the penile skin, as penile urethral erosion is a rare but potential complication of chronic indwelling catheterisation with a lack of available recommendations for reconstructive options. PATIENT AND METHODS: A 44-year-old male with paraplegia, neurogenic bladder dysfunction and chronic sacral decubitus, presented with a large mid-penile erosion of the ventral penile shaft and urethra, which was caused by chronic transurethral indwelling catheterisation while being hospitalised in an intensive care unit. The reconstruction involved a single-stage dorsal-inlay buccal mucosa graft urethroplasty (Asopa) in addition to the second stage of a two-stage urethroplasty. The urethroplasty as well as the buccal mucosa graft harvest were performed by a single team. RESULTS: The modified single-stage urethroplasty procedure had a duration of 158 min with a postoperative hospitalisation of 3 days. At 8-months follow-up, the lesion had fully healed and the patient was back on clean intermittent self-catheterisation with solifenacin 10 mg daily. No complications occurred postoperatively. CONCLUSION: The modified single-stage dorsal-inlay technique is a viable method for repairing ventral penile urethral erosion with involvement of penile skin.
