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...

INTRODUCTION: To study the impact of caudal block (CB) versus dorsal penile block (DPB) on the rate of urethrocutaneous fistula (UCF) and glans dehiscence (GD) in children who underwent hypospadias repair. METHODS: We conducted a retrospective review of consecutive patients who underwent tubularized incised plate repair between 2004-2015 (n=849). Incomplete medical records, other techniques and re-do cases were excluded(n=331). Preference for CB was based on anesthesiologist's discretion...

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...

BACKGROUND: Several techniques have been used to repair mid-penile hypospadias; however, high failure rates and major complications have been reported. In this study, we describe a novel technique using a well-vascularized flap of the inner and outer preputial skin. METHODS: A total of 110 male children with hypospadias underwent repair by our technique between 2008 and 2015. The inclusion criteria were children with mid-penile or slightly more proximal hypospadias, with or without ventral chordae, and an intact prepuce of the cobra eyes variety...

INTRODUCTION: Hypospadias is a congenital abnormality of the penis, in which there is incomplete development of the distal urethra. There are numerous reports showing na increase of prevalence of hypospadias. Association of craniofacial malformations in patients diagnosed with hypospadias is rare. The aim of this study is to describe the association between hypospadias and craniofacial congenital anomalies. MATERIALS AND METHODS: A retrospective review of the Latin-American collaborative study of congenital malformations (ECLAMC) data was performed between January 1982 and December 2011...

INTRODUCTION: Patients with hypospadias are treated surgically during childhood, which has the intention of enabling a satisfactory sexual life in adulthood. However, it is unclear whether patients with corrected hypospadias can lead a satisfactory sexual life and sustain a marital relationship and produce offspring. AIM: To evaluate factors associated with achievement of sexual intercourse, marriage, and paternity in patients with hypospadias who have reached adulthood...

STUDY QUESTION: Are maternal first trimester levels of serum free-beta hCG associated with the development of hypospadias or undescended testis (UDT) in boys? SUMMARY ANSWER: Overall, first trimester maternal levels of serum free-beta hCG are not associated with hypospadias or UDT. However, elevated levels were found in severe phenotypes (proximal hypospadias and bilateral UDT) suggesting an altered pathway of hormonal release in early pregnancy. WHAT IS KNOWN ALREADY: Human chorionic gonadotrophin peaks in first trimester of pregnancy stimulating fetal testosterone production, which is key to normal male genital development...

Complications in hypospadias surgery are not uncommon however penile skin or flap necrosis is rarely reported. Ischemia of the flap or graft is a major complication in two stage repair of hypospadias. A 2-year old boy with proximal penile hypospadias, operated earlier for chordee correction and urethral plate formation with a preputial flap, presented for stage 2 repair. Ten days after surgery patient developed skin and neourethral necrosis. Early debridement was done followed by coverage with scrotal flaps...

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...

INTRODUCTION: The use of preoperative hormonal stimulation before hypospadias surgery aims to increase penile size and achieve better surgical results; however, the rules are not clear in the literature. We evaluated the effects of topical testosterone and estrogen in the hypospadic penis regarding biometric measures, side effects, and serum hormonal levels. To our knowledge, this is the first study using estradiol prior to hypospadias surgery. PATIENTS AND METHODS: Sixty-nine children with hypospadias were randomly divided into three study groups: a control group (CG) of 17 children given placebo cream; a testosterone group (TG) of 28 children who used 1% testosterone propionate; and an estradiol group (EG) of 24 children using 0...

INTRODUCTION: A variety of techniques are available for proximal hypospadias repair. Onlay, proximal tubularized incised plate (TIP), and Duckett are among the popular choices because they can be performed as a one-step procedure. However, the decision to select a procedure often comes down to the surgeon's preference rather than that supported by evidence-based data. In particular, there is a paucity of literature on the long-term urinary outcomes after proximal hypospadias repair. OBJECTIVE: The aim of this study was to evaluate the evolution of long-term uroflowmetry parameters after proximal hypospadias surgery over a long-term follow-up including the adolescent period...

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)...

REVIEW
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...
