“…Despite the elimination of adverse effects related to ionizing radiation, the limitations of the voiding urosonography were a requirement of catheterization and echocontrast media usage. [6][7][8] In these studies, another evaluation method of VUR was visualization of Doppler signals (retrograde flow into the ureter) from the bladder to ureter during the course of bladder filling by using a color Doppler US. This procedure could be applied only patients aged ≥2 years because it required compliance from the patients.…”

Background: Vesicoureteral reflux is the most common urinary congenital anomaly in children. Given the risk associated with radiation exposure there has been an increasing need for radiation-free method in the diagnosis and follow-up of the vesicoureteral reflux. The aim of our study is to compare conventional urosonography without contrast enhancement and x-ray voiding cystourethrography.Patients and Methods: Children with recurrent urinary tract infection with suspected vesicoureteral reflux were included to the study. Vesicoureteral reflux is demonstrated and graded by x-ray voiding cystourethrography. DMSA is used for the evaluation of renal scar. Conventional sonographic procedure was performed in all patients. Ureterovesical junction insertion angle was evaluated. The diameter and length of the ureterovesical junction were also measured.Results: 268 children enrolled to the study. Vesicoureteral reflux was demonstrated in 62 children by x-ray voiding cystourethrography. Ureterovesical junction insertion angle measurement had a statistically significant relation for right and left vesicoureteral reflux presence (right: r: .646, p: .01 and left: r: .446, p: .01). Diagnosis sensitivity of vesicoureteral reflux with conventional ultrasonography is 95.10% and specificity is 81% (Youden’s index 76.1%) for the cutoff value of the ureterovesical junction insertion angle is 28.6 degrees. Positive predictive value is 87.2%, negative predictive value is 94.73% and diagnostic accuracy is 86.29% with conventional ultrasonography.Conclusions: Measurement of ureterovesical junction insertion angle, length and diameter by conventional urosonography is an easy accessible and cheap technique with high sensitivity and specificity for the diagnosis and followup of the vesicoureteral reflux without exposure to ionizing radiation.

“…Die meisten Eltern, die nach einer Pyelonephritis den bereits bei Entlassung aus der stationären Behandlung geplanten Termin für ein MCU nicht wahrnehmen, tun dies aus Angst vor der Strahlenbelastung [25] Direkte Refluxprüfung ist invasivob sonografisch oder radiologisch! Die Methode der Refluxprüfung hat kaum einen Einfluss auf die Therapieentscheidung nach einer Refluxdiagnose [26]. Sämtliche Verfahren zur Refluxdiagnostik stellen jedoch eine relevante Belastung für das betroffene Kind dar.…”

ZusammenfassungDas radiologische Miktionszystourethrogramm gilt in der Kinderurologie seit Langem als Goldstandard zur Refluxprüfung. In den zurückliegenden Jahrzehnten haben sich daneben zusätzliche kontrastmittelgestützte Verfahren wie die sonografische Refluxprüfung oder die Radionuklidzystografie etabliert. Ihr Hauptindikationsgebiet liegt in der Reflux-Diagnostik nach Pyelonephritis im Säuglings- und Kindesalter. Für die Auswahl der geeigneten Methode spielen klinische Fragestellung, Verfügbarkeit, ökonomische Aspekte, personeller und zeitlicher Aufwand und das Ziel der geringstmöglichen Strahlenbelastung bei maximalem Informationsgehalt eine Rolle. Moderne Strategien streben unabhängig von der Methode der Refluxprüfung eine risikoorientierte, individuelle Indikationsstellung an.
