Usefulness of digital subtraction angiography for diagnosis of renal tumours.

DSA (digital subtraction angiography) is a new, highly effective method for visualization of kidney vascular system. By means of a digital subtraction angiography unit the image of bones and soft tissues is blotted out, and a subtractive picture of contrasted vessels alone emerges. Intra-arterial DSA is a less invasive and more comfortable method when compared to conventional angiography. Only 2-4 ml of contrast medium is administered, thinner catheters being employed at the same time. The examination can also be performed through intravenous administration of contrast medium. The DSA unit Angiotron CMP was installed at the Department of Radiology, Military Medical Academy of Lódz, in 1984. In the present material a diagnostic DSA investigation was performed in 22 patients with renal tumours. In 21 of them the tumour was correctly diagnosed on grounds of pathological vascularization and the result was dubious in only 1 patient with benign tumour.

[Incidence of urinary tract diseases among workers in the Masovian Refining and Petrochemical Plants in Plock 1978-1981]. / Czestosc wystepowania chorób narzadów ukladu moczowego u pracowników Mazowieckich Zakladów Rafineryjnych i Petrochemicznych w Plocku w latach 1978-1981.

The studies were aimed at estimation of the incidence rate of genito-urinary tract diseases among employees of the Mazovian Refining and Petrochemical Plants in Plock. In 1978-1981, 873 employees were examined, including 244 females and 629 males. Most of them, namely 572 (65%), were employed in those plants for more than 5 years. In 190 persons (21.8%) either history of urologic diseases (41 persons) or current diseases (149 persons) were found. The incidence rate of genito-urinary tract diseases was similar to that observed in general population. The studies are continued.
