Urethrocutaneous fistula (UCF) is a common complication of hypospadias surgery for severe hypospadias. We report our experience in the management of UCF following hypospadias surgery with a prepuce-degloving method (PDM). Our study included 87 patients who developed UCF after hypospadias repair from May

A case control study of hypospadias was performed from 1979 to 1987 in Alsace, north-eastern France. A total of 176 out of 60 847 male infants had hypospadias giving a prevalence at birth of 2.89 per 1000 male newborns; 15.3% of all infants with hypospadias also had other malformations. Renal and urinary tract malformations were present in 37.0% of the infants with hypospadias and other additio...

The last decade has witnessed an alarming increase in the worldwide incidence of hypospadias. For non-hypospadiologists, the surgical correction of hypospadias will be increasingly demanding. This paper aims to evaluate the effectiveness of a treatment strategy devised by a single-surgeon practice in Malaysia to tackle this anticipated surge of caseload. Over a period exceeding eight years, 254...

Background: In this study, the results of "Urethral Advancement & Glanuloplasty" in repairing anterior hypospadias were considered. Hypospadias is a common urethral anomaly in boys. More than 65 percent of hypospadias cases are anterior (glanular, coronal and distal penil shaft). More than two hundreds original techniques have been applied to correct hypospadias. Each of these techniques has so...

Hypospadias is one of the most common congenital malformations among children. Both gene mutations and environmental factors are thought to be involved in the development of hypospadias. The mastermind-like domain-containing 1 gene (MAMLD1, formerly CXorf6) is a new candidate gene and its mutation has been shown in some cases of hypospadias. Here, by direct sequencing of PCR products, we assess...

BACKGROUND Hypospadias is associated with twinning. The incidence of hypospadias in monochorionic and dichorionic male twins is, however, yet to be determined. METHODS All medical records of monochorionic and dichorionic twins admitted to our neonatal nursery between January 2004 and August 2013 were reviewed for the presence of hypospadias. RESULTS A total of 350 monochorionic and 303 dich...

BACKGROUND Some studies have suggested an association between paternal subfertility and hypospadias among their sons, although the association has not been systematically investigated. We therefore compared male reproductive health among a group of fathers of boys with hypospadias and a group of fathers to normal children. METHODS A total of 64 fathers of boys with hypospadias participated; 3...

Introduction : Hypospadias can be defined as an abnormal urethral orifice under surface of the penis with or without chordee and with or without dorsal hood. At a critical time in sexual differentiation of the male fetus, HCG enters fetal plasma from syncytio trophoblast; acts as an LH surrogate and stimulate replication of testicular Ley dig cells and testosterone synthesis to promote male sex...

BACKGROUND An increase in the prevalence of hypospadias has been reported, but the environmental causes remain virtually unknown. OBJECTIVES Our goal was to assess the association between risk of hypospadias and indicators of placental function and endogenous hormone levels, exposure to exogenous hormones, maternal diet during pregnancy, and other environmental factors. METHODS We conducted...

abstract: Hypospadias is one of the most common congenital malformations. Few studies have explored the association of age at time of surgery and the occurrence of complications after hypospadias repair. We undertook this study to determine whether age at hypospadias repair is a risk factor for development of complications. Hypospadias is one of the most common congenital malformations. Few stu...
