background and purpose: posterior urethral valve (puv) is one of the most severe urinary tract anomalies presenting as antenatal hydronephrosis that could lead to severe dilatation and functional impairment of one or both kidneys. the aim of this study was to analyze our experience on patients with a diagnosis of puv. materials and methods: in this prospective study neonates with a diagnosis of...

INTRODUCTIONS The widespread use of prenatal ultrasonography results in increased recognition of congenital hydronephrosis, a therapeutic and diagnostic challenge. This study was conducted to investigate the natural course of prenatal hydronephrosis and the accuracy of postnatal APD in determining the outcome. MATERIALS AND METHODS All newborns with prenatal hydronephrosis were followed up by...

Medical ultrasound is a particularly useful imaging method used in the diagnosis of urinary foetal anomalies. One such anomaly posterior urethral valve (PUV), which congenital malformation male urethra occurring early gestation life. PUV common cause obstructive uropathy males and death during pregnancy. We report from medical perspective on rare high-risk case detected routine antenatal Botswa...

the outcome and proper management of fetal hydronephrosis have not been completely defined. the purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. in a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more...

A full-term baby boy underwent an ultrasound scan of the abdomen at 6 weeks of age for the follow-up of an antenatal diagnosis of left-sided hydronephrosis. Although there was no hydronephrosis, the abdominal ultrasound revealed an enlarged liver with multiple hypoechoic lesions measuring up to 25 mm in diameter. He was admitted to the hospital for further evaluation of the hepatic lesions. Exa...

PURPOSE Antenatal hydronephrosis (AH) is found in 0.5%-1% of neonates. The aim of the study was to assess the urinary concentrations of 3 biomarkers, endothelin-1 (ET-1), monocyte chemotactic peptide-1 (MCP-1), and N-acetyl-glucosaminidase (NAG) in severely hydronephrotic neonates. MATERIALS AND METHODS Neonates with a history of prenatal hydronephrosis were enrolled in the prospective study ...

Purpose: Ureteropelvic junction (UPJ) obstruction is by far the most common cause of pediatric hydronephrosis. The widespread use of antenatal ultrasonography and modern imaging techniques has resulted in earlier and more common diagnosis of hydronephrosis. However, compared with this increased earlier detection, little has changed regarding the management of hydronephrosis. Through this review...
