RESUMO
A critical study of various techniques for end-to-end vaso-vasostomies without or with internal splints on 41 dogs is presented. The results of vaso-vasostomy without any internal splint were significantly better than those with splints, both for primary as well as secondary repair after 6 weeks. The presence of an internal splint was associated with a high incidence of severe infection in the vas, epididymis and testis. An end-to-end mucosa-to-mucosa anastomosis using either 6/0 silk or Prolene under magnification is recommended as a simple and successful methods of recanalisation of the vas in clinical practice.

An electron optical investigation of the morphology of the colloidal matrix of renal and vesical urinary calculi revealed the presence of several morphologic forms hitherto unknown. Earlier light microscopic studies indicated that the matrix exists either as fibrils or as an amorphous matrix. The electron micrographic scanning of specimens of calculi revealed the following matrix morphologies: (i) flaky, (ii) serrated, (iii) perforated (globular), (iv) hollow tubular, (v) fibrillar, (vi) cylindrical, and (vii) pear-drop shaped. Crystalline matter was not associated with flaky and serrated matrix particles. However, some matrix particles of perforated (globular), fibrillar, and cylindrical morphologies were found to be calcified.

A clinical, radiographic and endoscopic study of 34 children suffering from vesical calculus disease and manifesting ureteric reflux has been presented. The oedema and inflammatory changes from the vesical calculus and infection were responsible for the reflux in the majority of these children. The reflux was eradicated by simple removal of the stone. The importance of detailed urological investigation of all the children presenting with lower urinary tract calculi has been emphasised.
