Patients with impaired renal function require thorough evaluation at the time of diagnosis and careful supervision thereafter. If renal failure ensues, both dialysis and renal transplantation can be used to provide integrated and total care. The family physician has an important role to play in medical supervision of patients undertaking dialysis at home. Discussion and careful examination during routine visits can forestall complications and contribute to the patient's confidence and independence. There are few problems that cannot be sorted out by an interested family physician with support from the parent renal unit.
