[Kidney and urinary tract injuries. Experience with 113 cases].

Background: Trauma of the kidney and urinary tract is not rare in emergency surgery and the related treatment needs today high competence and interdisciplinary approach. Aim of the study was to analyze the personal experience in order to find differences in the treatment during the last years especially for trauma of the kidney.

Methods: The authors report 113 cases of kidney or urinary tract trauma out of 16,569 patients admitted in emergency between 1981 and 1995.

Experimental models in microsurgery.

The development of experimental microsurgery can be considered the natural evolution of a diffuse need to increase precision in many fields of surgery. Microsurgery accelerated the possibility of deepening many unclear aspects of pathophysiology, using miniaturized and reproducible experimental models. We report briefly on the fundamental principles of microsurgery and the most frequently performed and useful models of experimental microsurgery, especially to employ as training models for surgeons, but also as bases for developing new and always-welcome models.

[Advantages of reabsorbable intradermal sutures in general surgery. Experience on 201 sutures].

Surgical wound suture is often considered of minor importance compared to the whole surgical operation. The aesthetical result of a wound suture is still hardly considered in general surgical practice compared to other "traditional" wound sutures. The Authors carried a prospective study an 201 intradermal absorbable sutures in clean general surgery.

Misplacement of a jugular line in a facial vein.

We report an exceptional misplacement of a central venous catheter, from the right jugular vein where it was introduced, into the right thyro-lingual-facial trunk. A brief description of the clinical course and a literature review on catheter misplacement is presented. This case illustrates the importance of routine use of a chest X-ray, and when necessary contrast medium, to verify the correct location of the catheter tip.
