Vesicoureteral reflux (VUR), the retrograde flow of urine from the bladder toward the kidney, is congenital and often familial. VUR is common in childhood, but its precise prevalence is uncertain. It is about 10–20% in children with antenatal hydronephrosis, 30% in siblings of patient with VUR and 30–40% in children with a proved urinary tract infection (UTI). Ultrasonography is a u...

Background: This study evaluates the accuracy of renal ultrasonography (US) in the detection of vesicoureteral reflux (VUR) compared to voiding cystourethrography (VCUG). Martials and Methods:We retrospectively reviewed the medical records of 131 children with urinary tract infection. Ultrasound findings were considered to be suggestive of VUR if a “pelvocalyceal dilatation”‚ “retrovesical uret...

BACKGROUND The invasiveness and exposure to radiation in voiding cystourethrography led to the introduction of alternative methods of diagnosis of vesicoureteral reflux, including contrast enhanced voiding urosonography. While there is a limited number of studies comparing these methods using new generation ultrasound contrast agents, none of them compared both methods simultaneously. This stud...

Introduction. The diagnosis of detrusor-external sphincter dyssynergia (DESD) is a clinically relevant finding during urodynamic testing. However, there is no consensus regarding diagnostic specifics of electromyography (EMG) or voiding cystourethrography (VCUG). We evaluated the concordance of the two modalities most commonly used in clinical practice for the diagnosis of DESD. Methods. Patien...

BACKGROUND Imaging of the kidneys and urinary tract has a significant and critical role for diagnosis of genitourinary system diseases. Although technological progress goes toward less invasive approaches, some of the current methods are still invasive and annoying. Voiding cystourethrography (VCUG) is the best and most accurate method for diagnosis and grading of vesicoureteral reflux. VCUG is...

INTRODUCTION. Urinary tract infection is the most common serious bacterial infection in children. The aim of this study was to compare the value of different laboratory and imaging techniques in detecting renal involvement in acute pyelonephritis. MATERIALS AND METHODS. In a cross-sectional study of patients 1 month to 14 years of age diagnosed with urinary tract infection were examined with sy...

Purpose: Urinary tract infection (UTI) is one of the important infectious diseases childhood age. It causes serious late-term complications by leading to development renal scarring in some pediatric patients. In present study, it was aimed determine risk factors damage patients that admitted with clinical acute pyelonephritis. Materials and methods: our medical files were nephrology polyclinic ...

Antenatal hydronephrosis (ANH) is one of the most common abnormal findings detected on prenatal ultrasound (US), and it has been reported in 1-5% of all pregnancies. The likelihood of significant postnatal pathologic abnormality in the urinary tract correlates with the degree of anterior-posterior diameter (APD) according to the gestational age. Detection of urologic anomalies prenatally permit...

INTRODUCTION We assessed the possible consequences of applying the National Institute of Health and Clinical Excellence (NICE) guidelines for imaging studies of children younger than 3 years with urinary tract infection (UTI) to clinical practice, in terms of altered diagnoses and treatment. MATERIAL AND METHODS In a retrospective cohort of 672 patients with UTI, we evaluated indications for ...
