Randomized Comparative Study Between Buccal Mucosal and Acellular Bladder Matrix Grafts in Complex Anterior Urethral Strictures

摘要: Purpose: Urethral strictures have been a reconstructive dilemma for many years due to the limited availability of tissue substitutes and incidence recurrence. Buccal mucosal grafts favored material in instances where penile skin is unavailable its durability excellent graft survival. Recently collagen based matrices derived from bladder used successfully patients with stricture disease hypospadias. We performed randomized comparative study assess outcome acellular matrix compared buccal mucosa complex urethral strictures.Materials Methods: Human demineralized bone matrix, obtained cadaveric donors, was processed prepared use as an off-the-shelf material. Thirty 21 59 old (mean 36.2) were enrolled assessed using standard protocol. The length ranged 2 18 cm 6.9), which 11 had bulbar, 7 pendulous 12 combined bulbopen...
