The hepatic veins were visualized on the early nephrogram film of an excretory urogram in a patient with tetralogy of Fallot. A nuclear angiocardiogram showed pulsatile reflux of blood from the right atrium into the hepatic veins.
The association of renal tuberculosis and leukoplakia of the renal pelvis was quite common in the prechemotherapy era of tuberculosis but has apparently not been seen since effective drugs became available. Despite a prompt response of the tuberculosis to chemotherapy the leukoplakia formation with intermittent passage of keratinised material continued. Surgical removal of the accumulated material was of no lasting benefit.
Retrospective analysis of 196 cases suggests that bronchography has limited value in the evaluation of hemoptysis. Most patients with a single episode of hemoptysis and normal plain chest roentgenographic and bronchoscopic findings do not require bronchographic examination. Advances in cytologic and biopsy procedures (fiberoptic bronchoscopy, bronchial brushing, needle aspiration) have largely replaced the usefulness of bronchography even when the plain chest roentgenogram is abnormal.
