The correct precystoscopic diagnosis of bladder tumor was made in 20 of 23 patients with this disease, among more than 1,000 persons studied by double-dose excretory urography. There was no increase in the incidence of untoward effects. Double-dose excretory urography with delayed bladder films is recommended as the primary urographic procedure in all patients with gross or microscopic hematuria in whom bladder tumor is suspected.
