vesicoureteral refluks, children contrast-enhanced urosonography

Sažetak
Vesicoureteral reflux (VUR) is an anatomical and functional abnormality caused by a non- physiological retrograde flow of urine from the bladder into the ureter and the renal canal system. VUR is one of the most common anomalies in children and it is the most common cause of renal scarring in children with a consequence of renal function damage. Diagnosis of VUR is based on 3 methods: voiding cystourethrography (VCU), radionuclide cystography (RNC) and contrast-enhanced voiding urosonography (ceVUS). Today, the sensitivity of ceVUS is very high (ranging from 80% to 100%) with high specificity (ranging from 77% to 97%). It has become a routine and professionally recognized method for the diagnosis of VUR in children. Data were collected retrogradely, from medical records of 183 children (age 1.7 ± 1.1 years) from 09/2016 until 12/2018. The test was conducted on a Philips Affiniti 50G ultrasound machine, with a 2.5 – 5 MHz convex probe. Sulfur hexafluoride (SonoVue 8 μL/mL) was used as the ultrasound contrast agent, with MI<0.1. Gender distribution, age, ceVUS indications, frequency of pathological findings in the urinary tract ultrasound, and the frequency of VUR In children with UTI: gender, age, characteristics of the UTI (relapse, febrility), distribution of pathogens, inflammatory parameters at the time of infection (leukocytes and CRP), and frequency of pathological findings of the urinary tract ultrasound.There is higher likelihood of underlying VUR in recurrent UTI, whereas gender, age, urinary tract ultrasound examination, severity, and other causative agents of UTI have no predictive value for VUR detection. Girls suffer from recurrent UTI significantly more often than boys. CeVUS is one of the best choices in modern nephrology for detection of VUR, with high sensitivity and negligible side effects
