Single-stage buccal mucosal graft urethroplasty for meatal stenoses and fossa navicularis strictures: a monocentric outcome analysis and literature review on alternative treatment options.

Recurrent meatal stenoses and fossa navicularis strictures represent some of the most complex uro-reconstructive challenges. Inlay BMGU proves to be a valid and efficient last-resort single-stage technique. However, higher recurrence risk must be considered and staged urethroplasty should be discussed individually. Prospective randomized controlled trials are needed to prove the superiority of flaps, grafts or staged approaches over each other in this context.
