The overall number of very elderly patients (>79 years of age) requiring renal replacement therapy is rising in the Western societies, with a choice for managing advanced chronic renal disease among hemodialysis, peritoneal dialysis, kidney transplant, conservative, or palliative care. The selection of the most adequate alternatives should be tailored to meet individual needs, considering variables such as patient's choice, clinical status, and social context, analyzed from a geriatric perspective, aiming not only to prolong patient's life expectancy, but also to improve the patient's quality of life. Frailty and sarcopenia are highly prevalent comorbidities found in very elderly population, particularly in the end-stage chronic renal disease population. Both comorbidities have a strong negative impact on health general status, and specific treatment should be provided in conjunction with the selected management for renal replacement, except when a palliative care has been implemented. Moreover, the detected degree of frailty in a renal patient can have an important influence on the decision about which modality of renal replacement treatment will be selected. All these alternatives and considerations are discussed in the present review article.
