Modified tubularized incised plate urethroplasty for hypospadias repair: a long-term results of 764 patients.

Objectives: To present our experience with a modification of tubularized incised plate (TIP) urethroplasty for treatment of anterior penile hypospadias.

Methods: A total of 764 children with primary anterior penile hypospadias (462 subcoronal and 302 coronal) underwent hypospadias repair by using modified TIP urethroplasty. The technique involves, in addition to the standard TIP, the use of the dorsal prepuce which was divided in 2 flaps.

Randomized comparative study between buccal mucosal and acellular bladder matrix grafts in complex anterior urethral strictures.

Purpose: Urethral strictures have been a reconstructive dilemma for many years due to the limited availability of tissue substitutes and incidence of recurrence. Buccal mucosal grafts have been a favored material in instances where penile skin is unavailable due to its durability and excellent graft survival. Recently collagen based matrices derived from the bladder have been used successfully in patients with stricture disease and hypospadias.
