ABSTRACT Distal urethral strictures involving the meatus and fossa navicularis present unique challenges for reconstructive urologists due to the short segment’s proximity to the glans and high stakes for cosmetic and functional outcomes. Traditional approaches such as ventral meatotomy, skin-flap urethroplasty, and 2-stage techniques are known to compromise cosmesis, increase the risk of urethrocutaneous fistula, and have high recurrence rates, particularly in patients with lichen sclerosis (LS). The evolution of one-sided dorsal onlay urethroplasty with buccal mucosa graft has increased the success rates of single-stage urethroplasties by emphasizing preservation of tissue vascularity, leading to robust graft support. Traditionally, literature described the one-sided dorsal onlay urethroplasty through a perineal incision. This review seeks to describe the refinement of this technique, adapting the one-sided dorsal onlay concept to distal strictures by accessing the urethra through a subcoronal, ventral, or penoscrotal incision. Ventral penile incisions may limit unnecessary dissection, preserve glans architecture, and allow for supine positioning, thereby mitigating risks associated with high dorsal lithotomy. All while retaining the advantages of a well-vascularized dorsal graft bed. Limited reports describe high rates of anatomic and functional success and low complication rates across etiologies, including LS, iatrogenic, and hypospadias repair. Failures tend to be focal and amenable to minor interventions.
