ABSTRACT
The efficacy of lymphography and computed tomography (CT) in staging nonseminomatous testicular cancer was analyzed in 41 patients. Retroperitoneal lymphadenectomy in 30 patients with early tumor stage revealed 56% sensitivity, 90% specificity, and 80% overall accuracy for lymphography; CT was less accurate (44% sensitivity, 81% specificity, 70% overall accuracy). The presence of advanced disease in 11 patients was depicted equally by lymphography and CT, but CT better demonstrated the anatomic extent of the metastases. CT is valuable for discriminating between advanced and early tumor stages; the similar inaccuracy of lymphography in early disease militates against its routine and complementary use; retroperitoneal lymphadenectomy then remains the only accurate staging modality.

The radiological morphology of indirect rupture of the diaphragm is described; this may be followed by transdiaphragmatic prolapse of viscera, possibly complicated by strangulation or incarceration. The differential diagnosis is discussed with reference to fifteen cases seen by the author(s).

Based on a retrospective study of 14 patients with pancreatic pseudocysts, the ultrasonic evaluation of the pancreas is discussed and correlated to the conventional radiologic, endoscopic and angiographic examinations. The pancreatic sonography, as a non-invasive examination, is the method of choice for pancreatic screening and is recommended whenever a pancreatic pseudocyst is suspected.

The hemodynamic changes during intravenous urography were studied in 120 non-selected patients (60 patients with bolus injection, 60 with infusion: 30 of each group with methylglucamine ioxitalamate, while the other 30 with sodium methylglucamine diatrizoate). There was a uniform statistically significant increase in heart rate (p less than 10(-9) as well as in cardiac output (p less than 10(-9)) (measured by means of a non-invasive impedance method). The observed changes were more marked following bolus injection than infusion. With the application of methylglucamine ioxitalamate the increase in heart rate, but not in cardiac output, was significantly less (p less than 0,01) than with that of sodium methylglucamine diatrizoate.
