Urachal remnants: from embryology to clinical practice.

The urachus is a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.

Symptomatic Intraparenchymal Epididymal Cysts: Description of 11 cases.

Epididymal cysts are benign cystic formations of the epididymis that usually appear in adolescence or early adulthood. Their frequency doubles after the age of 14-15. Obstruction in the epididymal efferent ductules with subsequent prostenotic dilatation of them, as well as dysgenesis due to hormonal disorders during fetal or postnatal life, are possible.

Hutch diverticulum: from embryology to clinical practice.

Hutch Diverticulum (HD) is defined as the protrusion of the mucosal and submucosal layer through the muscle bundles of the underlying detrusor muscle. HD is located at the vesicoureteral junction with a backward direction from the homolateral ureteral orifice. As far as its etiology is concerned, HD is caused either by a congenital muscle wall defect at the level where the Waldeyer's fascia occupies the clefts between the vesical part of the homolateral ureter and the detrusor, or is associated with abortive ureteral duplication or defective incorporation of mesonephric duct into the bladder at the site of ureteral hiatus or finally is associated with the development of transient urethral obstruction.

New insights about prognosis of Spermatic Cord Torsion.

Spermatic Cord Torsion (SCT) is a serious surgical emergency. Prospective studies regarding the prognosis of the torsed testis lack in the global literature. Prompt diagnosis and treatment are crucial to increase the risk of saving the torsed testis.

The challenging diagnosis of acute scrotum: remaining difficulties and further insights.

The main target during management of a male pediatric patient with clinical signs of acute scrotum is the timely diagnosis, in order not to jeopardize the viability of the affected testicle. Thorough evaluation of the patient's medical history, symptomatology, clinical and ultrasonographic findings, constitutes the basis of the diagnostic procedure. After comprehensive research of the relevant literature, we highlight the remaining difficulties in the evaluation of the clinical and ultrasonographic findings for the accurate diagnosis of the acute scrotum.

Antimesenteric gastrointestinal tract duplication undergoing non-ulcerative perforation.

Duplications of the gastrointestinal tract are rare malformations, most commonly presenting as cystic structures growing within the smooth muscle wall. Very rarely, they are completely detached from the tract. Several theories have been proposed regarding their embryological development, but no single one has been able to account for all of the described variants.

Enterobius Vermicularis-Associated Pelvic Inflammatory Disease in a Child.

Background: Enterobius vermicularis is the most highly prevalent intestinal worm in childhood and is generally considered of low pathogenicity. Little is known about the inflammatory complications of the female genital tract induced by E. vermicularis in childhood.

The role of laparoscopy in the management of adnexal lesions in children.

Aim: Laparoscopy has replaced laparotomy in a variety of surgical abdominal conditions. In pediatric patients the vast majority of adnexal lesions are benign. The aim of this study was to assess the safety and feasibility of laparoscopy in adnexal pathology in children.

New insights into the pathogenesis of infantile pyloric stenosis.

Infantile hypertrophic pyloric stenosis (IHPS) is the most common surgical cause of vomiting in infants. Despite numerous hypotheses, the aetiopathogenesis of IHPS is not fully understood. Genetic, extrinsic and hormonal factors have been implicated in the pathogenesis of the disease.
