Management of fossa navicularis strictures

The fossa navicularis constitutes the distal segment of the anterior urethra, located within the glans penis and terminating at the meatus. Embryologically, the epithelium of the fossa navicularis develops by canalization of an ectodermal cord of cells, the glanular plate, which extends from the meatus into the glans. Strictures involving the fossa navicularis have distinct etiologic characteristics, and their management is particularly challenging. Successful reconstruction requires the creation of a functional urethral conduit while maintaining a cosmetically appealing glans penis.
