Duplex collecting system is a common congenital urinary system anomaly and is usually asymptomatic. Vascular variations associated with a duplex system are common but haven't been reported as obstructive. 14-month-old female had a right sided incomplete ureteral duplication complicated by lower pole hydroureteronephrosis due to distal ureteral obstruction by an aberrant vessel crossing the bifid ureters at ureteric junction of these bifid ureters. Prenatal imaging detected right hydronephrosis. Magnetic resonance suggested a diagnosis of duplicated ureters. At surgery, an aberrant artery compressed the lower moiety ureter at the bifid ureteric junction. The stenotic section was resected and ureter segments were anastomosed. The occluding small artery was not resected to preserve vascularization. An anatomical vascular variation can cause proximal ureteral dilatation and segmental hydronephrosis in a bifid system.

The term exstrophy-epispadias complex refers to a group of midline defects ranging from epispadias to cloacal exstrophy. Bladder exstrophy is the most frequent malformation of this spectrum and it can present as a classical or a variant form. We report a case of a hybrid bladder exstrophy variant having some characteristics of both a duplicate bladder exstrophy and a superior vesical fistula. [ABSTRACT FROM AUTHOR]

We suggest extending testing to all patients undergoing gastrointestinal surgery who have had recently demonstrated SARS-CoV-2 infection (even if they tested negative on admission on nasal swab). We detected SARS-CoV-2 in peritoneal fluid from two children with prior nasopharyngeal detection of SARS-CoV-2 who developed complicated appendicitis. Similarly, patients with a recently demonstrated SARS-CoV-2 infection (although tested negative on admission on nasal swab) should be considered SARS-CoV-2 positive, as per the use of PPE and for the setting of the operating room.

The caecum is one of the rarest sites of intestinal duplication cysts. The most common symptomatology includes vomiting, abdominal pain, abdominal distention, palpable mass and rectal bleeding. Most of the duplications are diagnosed within the first two years of life, including prenatal diagnosis. Only few cases of caecal duplication have been reported in the literature up to the present day. We are going to present a case of a five-years old girl with caecum duplication who reached our ward due to abdominal distension with no other symptoms. [ABSTRACT FROM AUTHOR]

Laboratory investigations included renal function tests, hormonal examinations, urinalysis, and complete blood count which were all normal. A 3-day-old female newborn was consulted for paediatric urology because of an interlabial mass (Fig. A lower abdomen ultrasonography was also performed and it showed a normal uterus and both ovaries.

Background: Idiopathic varicocele is one of the causes of potentially correctable male subfertility. The mechanisms causing spermatogenesis impairment have yet to be clarified. The aim of this study is to analyze the effects of renal and adrenal metabolite reflux on testicular exocrine function in a rat experimental model. Materials and Methods: In the study, 45 male Lewis Stock adult rats, each weighing 300 g, were used. The rats were subdivided into three groups of 15 rats. In group A (control group) testicular volume and basal follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were measured at the beginning of the study and after 9 months. In group B, varicocele was induced by means of rings introduced in the left renal vein in order to cause a renospermatic reflux. In group C, similarly to group B, varicocele was induced after removal of left adrenal gland. The effects of varicocele on testicular function were then analyzed 3, 6 and 9 months after surgery. After 9 months, all rats underwent testicular biopsy. Results: Both groups B and C showed a reduction in testicular volume, an increase in FSH and a decrease in testosterone levels. These levels were higher in group B. Testicular histological assessment showed important structural abnormalities in group B rats. Conclusions: These data support the hypothesis that renal and adrenal metabolites enhance varicocele-induced testicular damage. This theory is supported both by hormonal impairment and testicular histological analysis. Copyright © 2004 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
