ABSTRACT
A patient is described in whom a crossed kidney was found. There was doubt whether this was due to displacement or ectopia of the kidney. A review of literature on this subject gave no answer to our problem. Considering the embryologic development of crossed ectopic kidney and the mechanism of kidney displacement across the midline we found a simple method by which the diagnosis can be made.

A new method is described with which ureteral strictures are visualized by antegrade ureteroscopy. Under direct vision a catheter is manipulated through the stricture, which is then dilated. This method is especially useful in patients with a ureteroenterocutaneostomy. A patient is described in whom this technique was successful after other endoscopic techniques had failed.

The density of microspheres injected before occlusion of a coronary artery, in the infarcted region [I], was compared with that of healthy, normal myocardium [N], from the same dog. The [I]/[N] ratio was measured at different days after infarction up to 2 weeks. The ratio was below unity before the ninth day and above that thereafter. The changes in microspheres density can be explained on the basis of microsphere loss from necrotic tissue and changes in infarct mass.
