Informed consent in high-risk renal transplant recipients.

Before performing a clinical, diagnostic, and/or therapeutic action, the doctor is required to provide the patient with a bulk of information defined as informed consent. This expression was used for the first time in 1957 during a court case in California and the two words--informed and consent--are used together to underline the fact that the patient cannot give his or her true consent without first receiving correct information concerning the medical act in question. With regard to the medicolegal aspects governing organ transplants, despite the bulk of detailed work performed by health service workers involved in this surgical field with the aim of preparing adequate informed consent models, this has not yet been accompanied by the necessary legislative development. The informed consent model to be presented to the kidney transplant candidate should include a detailed description of the recipient's comorbidity and should aim at reducing the number of medicolegal actions, which have become more and more frequent in the last few years due to the ever increasing number of patients considered as suitable for transplantation. Informed consent, therefore, should not be a mere bureaucratic formality to be obtained casually, but should be carefully stipulated together with the patient by the transplant surgeon. It is, in fact, an indispensable condition for transforming a potentially illegal action, that is, the violation of an individual's psychophysical integrity, into a legal one.

[The clinico-instrumental assessment of the vascular status of the uremic patient for the making of a vascular access for hemodialysis]. / Valutazione clinico-strumentale del patrimonio vascolare del paziente uremico per la confezione di accesso vascolare per emodialisi.

For almost twenty years the Institute of General Surgery and Organ Transplant at Palermo Polyclinic has dealt with vascular problems arising during the preparation, monitoring and search for vascular access in uremic patients. For a number of years advantage has been taken of the vascular status in uremic patients; in fact, the possibility of creating a long-lasting and efficient vascular access also depends on the optimal use of the patient's vascular resources. The authors briefly describe the clinical and instrumental diagnostic strategy for the approach to a vascular access in uremic patients which must be correct and must respect the vascular resources of a "chronic" patient by definition, for whom hemodialysis is often the only prospect of therapy.
