Abstract

Positional instillation of contrast (PIC) cystography is effective for detecting occult vesicoureteral reflux (VUR), which can not be revealed by standard voiding cystourethrography (VCUG). We experienced two cases of young female patients; one had repeated urinary tract infection with a negative VUR on standard VCUG, and the other had findings suggestive of reflux hydronephrosis and intolerance of standard VCUG. They underwent PIC cystography, and occult VUR was detected in both cases. Both were successfully treated with simultaneous endoscopic injection therapy with dextranomer/hyaluronic acid. PIC cystography is useful for detecting occult VUR in children with negative VUR findings on standard VCUG or who are unable to tolerate standard VCUG.
