Hypospadias is a relatively common genital condition in which the urethral opening forms on the underside of the penis, as opposed to at the tip of the glans. Patients with hypospadias are typically referred for surgery during infancy or early childhood. Recent evidence, however, indicates that many individuals with hypospadias do not experience the functional or psychosocial difficulties commo...

Little is known on environmental risk factors for cryptorchidism and hypospadias, which are among the most frequent congenital abnormalities. The aim of our study was to identify risk factors for cryptorchidism and hypospadias, with a focus on potential endocrine disruptors in parental diet and occupation. In a case-control study nested within a cohort of 8,698 male births, we compared 78 crypt...

This case-control study investigated the association of transforming growth factor-β (TGF-β) receptor type I and II (TGFBR1 and TGFBR2) gene polymorphisms with the risk of hypospadias in a Chinese population. One hundred and sixty two patients suffering from hypospadias were enrolled as case group and 165 children who underwent circumcision were recruited as control group. Single nucleotide pol...

OBJECTIVE To explore the mechanisms of hypospadias induced by in utero exposure to din-butyl phthalate (DBP). METHODS Timed-pregnant Sprague-Dawley rats were administered 750 mg/kg of DBP by gavage from GD (gestation days) 13 to GD 18, whereas control group received corn oil. Genital tubercles (GTs) and blood samples were collected from male fetuses on GD 19. The serum testosterone concentrat...

Epidemiological and genetic variables in hypospadias were analysed during the years 1978 to 1983 in a case control study of congenital malformations in the Emilia Romagna region of northern Italy. During the observation period, in a sample of 41 078 male newborns, 168 had hypospadias giving a prevalence at birth of 4.1 in 1000 males. Hypospadias was divided into three types: type I or mild (75....

INTRODUCTION Of interest is if factors like maternal diet can influence the risk of hypospadias-affected pregnancy. Increased propionylcarnitine (C3) is regarded as a biomarker of vitamin B12 deficiency. The retrospective study was undertaken to determine whether increased propionylcarnitine and low methionine in newborns are associated with hypospadias. MATERIAL AND METHODS 41 newborns with ...

Tubularized incised plate urethroplasty (TIP) by Dr. Warren Snodgrass and Byar’s two stage urethroplasty were the only two basic methods applied. Only 13 patients (5%) of total required two stage repairs. Subsequent 10 years, I operated 512 cases of hypospadias with the Ten Commandments...

Background: Hypospadias is the most encountered congenital malformation of newborn penis. Refashioning urethra, both physiologically and aesthetically, requires a good surgical exposure to perform scrupulous surgery. To obtain such standards tourniquet application adrenaline injection have been performed in past but there still controversy for best results. Materials Methods: The files 78 patie...

Hypospadias is a congenital malformation that occurs in 0.3-1% of live births, in which the meatus (the urethral opening) is dorsally malpositioned. Uncorrected hypospadias can cause difficulties in urination, abnormal sexual function, and adverse psychological consequences; surgical correction, though generally successful, constitutes an economic burden for families. Several common classes of ...

Previous genome-wide association studies have identified variants in the diacylglycerol kinase kappa (DGKK) gene associated with hypospadias in populations of European descent. However, no variants of DGKK were confirmed to be associated with hypospadias in a recent Han Chinese study population, likely due to the limited number of single-nucleotide polymorphisms (SNPs) included in the analysis....
