BACKGROUND The etiologies of the male urogenital anomalies--cryptorchidism and hypospadias--are poorly understood. Given positive associations between chlordane isomers and testicular germ cell tumors, it is reasonable to assume that chlordanes might also be associated with other testicular dysgenesis syndrome disorders, namely cryptorchidism and hypospadias. OBJECTIVE To examine whether expo...

BACKGROUND Caudal and penile blocks are the most popular regional anesthetic techniques used in infants and children undergoing urological surgery. A recent report has suggested that penile venous pooling resulting from caudal blocks could affect surgical outcomes after hypospadias operations. OBJECTIVE The aim was to report our experience in patients with distal hypospadias undergoing repair...

BACKGROUND Hypospadias is one of the most common urogenital congenital anomalies affecting baby boys. Prevalence estimates in Europe range from 4 to 24 per 10,000 births, depending on definition, with higher rates reported from the United States. Relatively little is known about potential risk factors, but a role for endocrine-disrupting chemicals (EDCs) has been proposed. OBJECTIVE Our goal ...

This case-controlled study was designed to evaluate the association between various baseline parental factors and the risk of hypospadias in China. Patients were selected from tertiary referral hospitals in Anhui, a province in mid-eastern China. A questionnaire was given to the parents of each patient. The final database included 193 cases and 835 controls. The incidence of additional coexiste...

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 2001 to December 2011. Either simple closure or PDM was performed to repair the fistula. In ...

Introduction Hypospadias is a wide spectrum of abnormalities involving the inferior surface of the penis and having in common a urethral opening that lies on the inferior surface of the penis, (hypo = under; spadias = opening or rent). The spectrum of hypospadias anomalies includes an abnormal urethral opening, chordee (ventral curvature of the penis), an incomplete prepuce, rotation of the pen...

Objective: Hypospadias is known to have familial inheritance because of multifactorial etiology. Little is known about the genetic polymorphism involved in hypospadias. A few genetic associations have been reported but mainly in studies of small sample size and were based on case control stud . The aim of this study was to evaluate whether the genetic polymorphism ies usually seen in the affect...

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...
