[Renal cystography--a diagnostic and therapeutic procedure (author's transl)].

Pre-operatively, renal cysts can be distinguished with certainty from solid tumours only by their direct radiological demonstration; this is best done by double contrast methods after percutaneous puncture (renal cystography). By introducing a small amount of oily contrast medium, the cyst may be cured at the same time. The method is described and the results in different patients are reported. This combined diagnostic-therapeutic procedure is proposed as an alternative to surgery of renal cysts and is recommended as the method of choice in old patients and those carrying an increased risk.

[Results of post mortem thyroid gland phlebography (author's transl)].

The anatomic course and variation of the thyroid veins used for retrograde thyroid phlebography were studied in 70 post mortem thyroid phlebograms. Comparison with pathological and anatomical findings showed good agreement in benign diseases of the thyroid with lesions of more than 1 cm. Infiltrating malignant changes could not be delineated with certainty and a post mortem proven parathyroid adenoma was also missed. The practical clinical significance of thyroid phlebography is therefore confined to the localisation of parathyroid tumours in primary hyperparathyroidism by selective parathoromone measurements.

[Thyroid phlebography and selective venous sampling for parathormone estimations in primary hyperparathyroidism (author's transl)].

Selective venous sampling for parathormone estimations has become an important method in the diagnosis of primary hyperparathyroidism and, together with thyroid phlebography, is an accurate means for localising hormone active parathyroid tissue. Thirty-three patients were examined by this technique and in 25 of these an exploration was carried out subsequently. Twenty-one had primary hyperparathyroidism. In one case hormone analysis lead to a false positive finding. In 18 of these 21 patients, the hormone-active parathyroid tissue was correctly localised. Phlebography showed evidence of an adenoma in five patients, but is of most use for localising the source of the hormone.
