Abstract

Thirty-six children with urinary tract infection aged 6 months to 14 years (mean age 4 1/2 years) were studied sequentially using direct radionuclide (RNC) and conventional voiding cystourethrography (VCU). Vesicoureteral reflux (VUR) was detected equally well by both methods. Twenty-seven refluxing ureters were found by RNC, 23 by VCU and 22 by both methods. Radiologic grade of reflux may be determined approximately with the isotope technique from the volume of regurgitating urine and duration of reflux, at a much decreased radiation exposure. Residual urine was also measured by RNC and found to be higher in children with VUR. RNC is a reliable method for detecting and grading VUR and should effectively replace VCU as the follow-up examination of choice.
