[Chronic ulnocarpal calcareous bursitis].

There are reported three cases of nodular calcifications of the ulnocarpal region with very similar clinical and radiological aspects. The isolated nodules or the double, contigue one, are located near the pisiform bone, proximal to it, in the obliqual palmo-dorsal projection with semisupine hand. These nodules are projected on the ulnar styloid with the dorso-palmar projection.

[The surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG) in the study of azoospermias (author's transl)].

The Authors refer about their investigation of the azoospermias with surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG). Thirty-three patients were examined with DVG from a total of 50 observations. The Authors conclude that such investigation, associated to the study of others parameters in the male sterility, reveals itself very useful to provide information about azoospermias.

[Pyelocaliceal diverticula. Diagnostic problems: wash-out technique investigation and dynamic study (author's transl)].

The authors evaluated the pyelocaliceal diverticula by means of high dosis contrast urography with nephrotomography and following wash-out and dynamic examination. Most of cases showed stasis in the diverticulum. In no case dynamic activity of diverticulum walls was founded.
