Introduction: This study investigated whether renal and bladder ultrasonography (RBUS) findings performed in children with the first incidence of febrile urinary tract infection (UTI) can predict UTI recurrence, high-grade vesicoureteral reflux (high-grade VUR), or acquired renal scarring (aRS). Methods: In all, 917 children who were admitted to our hospital from January 2001 to October 2010, o...

Non-traumatic, spontaneous urinary bladder rupture is a rare complication of urethral stricture. Furthermore, its symptoms are often nonspecific, and misdiagnosis is common. The authors experienced a case of urethral stricture with spontaneous bladder rupture and bilateral hydronephrosis, mimicking obstructive uropathy attributed to cancer metastasis. A 55-year-old woman was admitted with abdom...

Patients with vesicoureteral reflux (VUR), the retrograde flow of urine from bladder to kidney, are known experience renal scarring; this results in worsening function. Reflux nephropathy is a cause chronic kidney disease, and VUR has also been observed dialysis patients. major underlying precursor condition urinary tract infection (UTI) sometimes accompanied by hydronephrosis. However, there n...

Antenatal hydronephrosis and vesicoureteral reflux (VUR) are common renal tract birth defects. We recently showed that disruption of the Robo2 gene is associated with VUR in humans and antenatal hydronephrosis in knockout mice. However, the natural history, causal relationship and developmental origins of these clinical conditions remain largely unclear. Although the hydronephrosis phenotype in...

The majority of pregnant women in the U.S. undergo prenatal ultrasonography and approximately 0.5% of these examinations will detect fetal malformations. Up to one-half of these abnormalities include the genitourinary system and the most common urological finding is hydronephrosis. Some conditions associated with prenatal hydronephrosis portend a poor prognosis, while others can follow a fairly...

BACKGROUND: Obstructive uropathy and hydronephrosis are common complications of cervical cancer. In order to provide an alternative route due ureteral obstruction, urinary diversion was performed. Urinary procedures a therapeutic option for obstructive but their effectiveness is remain unclear. There limited data that support as treatment obstruction improve overall survival progression-free su...

PURPOSE The aims of this study were to investigate the prevalence of upper tract involvement in ketamine-associated uropathy, and to determine the predictors of hydronephrosis in patients with a history of ketamine abuse. METHODS This was a cross-sectional study of a prospective cohort of patients with ketamine-associated uropathy. Data including demographics, pattern of ketamine abuse, pelvi...

BACKGROUND Congenital mid-ureteral stricture is a rare malformation of the ureter leading to prenatal and neonatal hydronephrosis. Site characterization of the narrowing is important to optimize the surgical approach to the newborn affected by hydronephrosis. CASE PRESENTATION We report a female EM with a rare form of hydronephrosis, (i.e. mid-ureteral stricture) which was detected early duri...

Background: Antenatal hydronephrosis is known to be associated with vesicoureteral reflux (VUR). However, the incidence of VUR in postnatally diagnosed hydronephrosis is unknown. Hypothesis: The prevalence of VUR is increased in infants diagnosed with hydronephrosis on postnatal ultrasonography. Methods: Infants admitted to our NICU between January 1998 and September 2007 and diagnosed with hyd...

Background Fetal hydronephrosis is a common urinary tract anomaly that may result in renal parenchyma damage. Ultrasound is considered a simple, noninvasive procedure to diagnose and track antenatal hydronephrosis. Our aim was to study the clinical course of fetal hydronephrosis in fetuses.
