Abstract:
The analysis of the body composition is of great importance in the follow-up of the dialysed patients, in order to evaluate the evolution of their nutritional state while taking account of their state of hydration. The problems are summarized by modifications of the various compartments in particular of the muscular mass, associated variations of the state of hydration, calling into question the constant ratios usually used, represented by a hydration of the lean body mass with 0,732, and a body hydration with 58%. The association of two independent techniques, or more, allowing measurements and the estimates of the various compartments (the hydration; fatty mass; mineral contents; the lean body mass) is the only way of obtaining results easy to interpret and reliable.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
