Correlation of ureteric jet angle (UJA) with vesicoureteral reflux grade and its assessment as a noninvasive diagnostic parameter to detect vesicoureteral reflux

Abstract Background Vesicoureteral reflux (VUR) is an essential urogenital entity affecting infants and younger children. Many patients present late with recurrent urinary tract infections (UTIs), which lead to chronic pyelonephritis, renal scarring, end-stage disease (ESRD). This progression in adds significant morbidity mortality the paediatric age group. Voiding cystourethrography (VCUG) investigation of choice invasive procedure related risk ionizing radiation iodinated contrast administration. Ureteric jet angle (UJA) a Doppler parameter that can be obtained by measuring between horizontal axis floor optimally distended bladder ureteric at ureteral opening into bladder. The study aimed (1) investigate correlation UJA VUR grade (2) assess utility as noninvasive diagnostic indicator diagnose alternative VCUG. Method All complaints were evaluated voiding for assessment grades VUR, followed colour evaluation jets. VCUG interpretations made.UJA was calculated long on examination. angles recorded both sides irrespective presence data analysed using SPSS. coefficient ( r ) p value calculated. efficacy (58° or more) detect assessed calculating sensitivity, specificity, PPV, NPV, positive LR negative LR. AUC evaluate 58° more VUR. Results In total, 34 (68 units) children (8 months–12 years), including 20 males (M) 14 females (F), examined. mean 4.96 ± 2.87 years total population, 4.60 2.02 boys 5.47 2.75 girls. Twenty-one (10 girls 11 boys) showed MCUG. Eight high (grade III–V), seven girl. range VUR-negative 27–60° median 42.03°. VUR-positive 32–71°with 62.13°. High-grade seen 8 59–84° 76.31°.
