Abstract Primary non-refluxing megaureter (PMU) is a congenital dilation of the ureter which not related to vesicoureteral reflux, duplicated collecting systems, ureterocele, ectopic ureter, or posterior urethral valves and accounts for 5 10% all prenatal hydronephrosis (HN) cases. The etiology dysfunction stenosis distal ureter. Most often PMU remains asymptomatic with spontaneous resolution allowing non-operative management. Nevertheless, in selective cases such as development febrile...

Vesicoureteral reflux (VUR) is the retrograde passage of urine from bladder to upper urinary tract. It most common congenital urological anomaly affecting 1-2% children and 30-40% patients with tract infections. VUR a major risk factor for pyelonephritic scarring chronic renal failure in children. result shortened intravesical ureter an enlarged or malpositioned ureteric orifice. An ectopic embryonal budding development implicated pathogenesis VUR, which complex genetic developmental...

Lymphatic Malformations (LMs) are benign congenital malformations of the lymphatic system that commonly involve abdomen in children (mesentery small intestine and omentum). The management these is not unique. 7 with different ages (range: newborn to 14 years), diagnosis was incidental some cases, while others for abdominal pain.

Background: Meckel’s diverticulum on the mesenteric side has been reported only as case reports in literature and presents a diagnostic challenge, with ultimate recognition often taking place intraoperatively. We describe series of children (MMD) treated at our institution, along results systematic review literature. Methods: Our experience MMD was analyzed performed according to PRISMA criteria. identified studies published from 1941 2023 PubMed, EMBASE, SCOPUS, WOS. Search terms were...

<b>Introduction</b> Carbon dioxide (CO₂) used in laparoscopy evokes local and systemic effects. This study was designed to evaluate the histopathologic morphologic changes due CO₂ air insufflation, at different pressure levels, on visceral parietal peritoneum rats. <b>Materials Methods</b> A total of 56 rats were object study, randomly divided into five groups. Pneumoperitoneum (PN) maintained for 30 minutes, a flow rate 0.5 L/min 10 6 mm Hg with (group S1–S2, <i>n</i>...

Background/Purpose: One-trocar surgery (OTS) includes all video-surgical techniques performed using a single 10-mm port and an operative scope. These can be completely endoscopic or assisted. Since 1997, OTS has become the approach of choice in our institution for variety laparoscopic, retroperitoneoscopic, thoracoscopic operations. We report experience with this technique. Methods: Four hundred fifty-eight patients (age range, 3 months to 17 years) underwent from October 1997 December 2008....

Abstract The Mild Combustion is a relatively novel combustion technique characicrized by both an elevated temperature of reactants and adiabatic flame not higher than 1600K. These features are the results several technological demands coming form different application fields. main advantages derived concern process itself its applications. In former case pollution reduction, increase efficiency fuel flexibility has to be considered whereas latter one principally related heat treatment wall...

Constipation is one of the most frequent disorders digestive tract in children and it can be an important problem paediatric surgical practice. Most time, cause psychological or because a slowing colonic transit, but sign organic gastrointestinal outlet obstruction.

Children in Group A had rectal suction biopsy (RSB) and contrast enema (CE), anorectal manometry (ARM) performed. Patients normal recto-anal inhibitory reflex (RAIR) underwent bowel disimpaction medical...

Transumbilical laparoscopic-assisted appendectomy (TULAA) is increasingly being performed worldwide. The authors report their experience in the treatment of acute uncomplicated appendicitis children with TULAA. From January 2008 to December 2012 all types were divided, according clinical and ultrasonographic findings, into complicated (appendiceal mass/abscess, diffuse peritonitis) uncomplicated. Complicated was treated by open (OA). All patients suspicion offered TULAA surgeons team....

Pediatric cholelithiasis unrelated to hematological disorders is an increasing disease. We analyzed our experience in the surgical treatment of these cases evaluate risk factors, clinical presentation, intervention and follow-up.From January 2010 December 2016, we retrospectively recorded all data (hematological study, familiarity, use lithogenic drugs parenteral nutrition) cholecystectomies for not related diseases. The body mass index (BMI) was calculated (obesity if > 25), medical...
