Background The aim of this study was comparison characteristics of family and demographics of children with antenatal hydronephrosis, in 2nd and 3rd trimester of pregnancy, in order to the need for postnatal management. Methods This cross-sectional study described some information from family of children with antenatal hydronephrosis, at the Pediatric Urology Research Center of Children's Hos...

Objective: The aim of this study was to determine if impaired distal ureteral contraction detected by urinary ultrasonography (US) could predict presence vesicoureteral reflux (VUR). Materials and Methods: A Retrospective analysis patients’ files between November 2016 September 2020 performed. total 248 children with demonstrated VUR on voiding cystourethrogram (VCUG) who underwent US within on...

Hydronephrosis is a commonly found disease state characterized by the dilation of renal calices and pelvis, resulting in the loss of kidney function in the severest cases. A generally accepted etiology of hydronephrosis involves the obstruction of urine flow along the urinary tract. In the recent years, we have developed a mouse model of hydronephrosis induced by lactational exposure to dioxin ...

The overall incidence of genitourinary abnormalities during routine prenatal US screening is 2±9 per 1000 births [1±5], with a male to female ratio of 2 : 1 [3]. The spectrum of genitourinary abnormalities detected in utero is extremely varied; most affected fetuses (50±87%) have hydronephrosis [6±8]. The remaining anomalies include multicystic dysplastic kidney, autosomal recessive polycystic ...

background & aim: we aimed to describe a standard survival analysis, so that we can analyze some factors related to the time of occurrence of different types of reflux (unilateral-left, unilateralright, and bilateral) in children with antenatal hydronephrosis (anh) and to provide an approach taking competing risks into account. methods & materials: we used data of 193 children that was collecte...

Urinary tract infection (UTI) is the most commonly diagnosed bacterial infection in infants and children, with a significant consequence on the quality of life and health [1]. Congenital urinary tract abnormalities are the most common cause of UTI in children. The most frequent kidney abnormalities encountered during childhood are: obstructions of urinary tract (urethral valves, ureteropelvic a...

The presence or absence of pelvicalyceal dilatation on postnatal ultrasound continues to appear within diagnostic algorithms to select patients for micturating cystourethrography (MCU) in the investigation of antenatally diagnosed hydronephrosis. Postnatal ultrasound findings were assessed in a population diagnosed as having antenatal hydronephrosis due solely to primary vesicoureteric reflux (...

BACKGROUND With growing ketamine abuse, ketamine-induced uropathy (KIU) has become more prevalent in recent years. This research evaluates the presence, distribution and extent of KIU in the upper and lower urinary tracts by retrospectively reviewing CT urography (CTU) images. METHODS Patients diagnosed with KIU who underwent CT scanning from 1 January 2006 to 31 December 2011 were recruited....
