Bladder Tumor Diagnosis—Improved Excretory Cystograms

摘要

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.
