OBJECTIVE: Snodgrass urethroplasty remains the preferred technique in primary distal hypospadias but development of meatal stenosis often limits distal extension of the midline incision of the urethral plate (MIUP), which remains a limiting factor in reconstructing an apical neomeatus (NM). We here-in assess the cosmetic and functional outcome with distal extension of the MIUP in grafted tubularised incised-plate urethroplasty (G-TIP) repair. PATIENTS AND METHODS: This prospective study included the surgical experience of 263 cases of primary hypospadias operated upon between 2012 and 2015...

INTRODUCTION: Within the veterinary world, data regarding the surgical management of hypospadias is lacking. Reports within equines have documented resective phallectomy procedures rather than urethral reconstruction. This case report documents the first ever urethroplasty for an equine hypospadias, performed by a consultant paediatric surgeon. The urethroplasty was achieved by applying the same surgical principles mastered from paediatric urology to a horse. The indication for surgery was contact dermatitis of the hind-leg, which impaired the thoroughbred foal's racing potential...

BACKGROUND: In the normal human penis, the glans wings merge in the midline ventrally, but are separated by the 'septum glandis' in conjunction with the frenulum. The frenulum is also included in the formation of the distal (glanular and subcoronal) urethra, which has a special part known as the 'fossa navicularis'. This has inspired a hypospadias repair technique that simulates the development of the glanular and subcoronal urethra, which can be incorporated into the repair of all cases of hypospadias...

OBJECTIVE: In principle, the prepuce can be reconstructed during hypospadias repair, but the procedure has not gained wide acceptance and preputial reconstruction (PR) is surrounded by several controversies. MATERIAL AND METHODS: A review is provided of the technique for PR, how PR combines with the other steps of hypospadias repair, the risks of complications related to the urethroplasty and specific to PR, and the results of PR with particular regard to the relevance for the patient and his family...

Hypospadias surgery is a humbling art form. The evolution of surgical techniques has made distal hypospadias outcomes favorable, but recent publications suggest that our complication rates for proximal hypospadias are much higher than previously reported. To explain these shortcomings, we examine the literature and focus on the lack of standardized documentation, the subsequent inability to objectify the severity of the phenotype, and the underestimation of complications due to lack of long-term follow up. The variability in surgical technique and the fact that the literature abounds with small case series from single institutions also limits our ability to compare outcomes...

INTRODUCTION: Anogenital distance (AGD) is a recognised marker of in utero androgen action. OBJECTIVE: This study aimed to evaluate the relationship between severity of hypospadias and AGD. STUDY DESIGN: Boys undergoing hypospadias repair in a single tertiary centre between May 2012 and February 16 were included in the study. Anogenital distance was measured from the centre of the anus to the base of the penis, and anoscrotal distance (ASD) from the centre of the anus to the junction between the smooth perineal skin and scrotal skin...

Hand-Foot-Genital syndrome is a rare autosomal dominant condition characterized by distal limb anomalies and urogenital malformations. This disorder is associated with loss-of-function mutations in the HOXA13 gene. HOXA13 plays an important role in the development of distal limbs and lower genitourinary tract of the fetus. We report a novel familial 589 kb deletion in the 7p15.2 region identified in a male toddler and his mother. The proband had severe penoscrotal hypospadias, mild skeletal anomalies of the hands and feet, cardiac, renal, and gastrointestinal anomalies...

We recently described a two-step process of urethral plate canalization and urethral fold fusion to form the human penile urethra. Canalization ("opening zipper") opens the solid urethral plate into a groove, and fusion ("closing zipper") closes the urethral groove to form the penile urethra. We hypothesize that failure of canalization and/or fusion during human urethral formation can lead to hypospadias. Herein, we use scanning electron microscopy (SEM) and analysis of transverse serial sections to better characterize development of the human fetal penile urethra as contrasted to the development of the human fetal clitoris...

BACKGROUND: Teaching and learning hypospadias repair is a major component of pediatric urology fellowship training. Educators must transfer skills to fellows, without increasing patient complications. Nevertheless, few studies report results of surgeons during their first years of independent practice. PURPOSE: To review outcomes of distal hypospadias repairs performed during the same 2-year period by consecutive, recently matriculated, surgeons in independent practice, and to compare them to results by their mentor (with >20 years of experience)...

C J Long, D A Canning
OBJECTIVE: Hypospadias surgery is a humbling art form. Although outcomes with distal hypospadias are favorable, recent publications have suggested that the complication rates are much higher than previously anticipated for proximal hypospadias. The present review examined the literature concerning proximal hypospadias, to explore some of the inadequacies and identify some of the reasons behind these shortfalls in the reported data. METHODS: A systematic review of the published literature was conducted using keywords relevant to proximal hypospadias and long-term outcomes...
