OBJECTIVE To determine the blood recirculation ratio in the vascular access of patients on hemodialysis, and to calculate the Kt/Vs obtained with the different techniques of arteriovenous fistula punctures. MATERIALS AND METHODS A total of 174 patients were divided according to the technique used for arteriovenous fistula puncture: group 1, needles in(More)
BACKGROUND In this study we evaluated bone abnormalities of patients with chronic renal failure (CRF) by cortical quantitative bone ultrasound (QUS) measurements at different bone sites because these abnormalities may be of variable etiology and may start before symptoms or radiological changes are manifested.
