The kidneys are responsible for discharging excess water and metabolic products in body. In Chronic Renal Failure, the kidneys are impaired seriously, which can cause the glomerular filtration rate (GFR) to decline, but the renal tubular function still remains normal. As a result, extra and sodium can not excreted and build up in body. Also the patients are often accompanied by the increased permeability of the systemic capillaries. The water will penetrate into tissues spaces resulting in swelling. As the tissues in face and leg are looser, the swelling usually occurs in those parts. This kind of swelling is common in Chronic Renal Failure caused by Nephritis.
In addition, as the glomeruli are damaged, they can not prevent the protein leakage into urine. Hence, the protein in blood decline greatly resulting in decreasing of plasma oncotic pressure. As a result, fluid in blood will penetrate into subcutaneous tissue.

If uncontrolled, the swelling will spread and even cause ascites, hydrothorax etc. They not only can cause burden to kidneys, but also can cause breath difficulty and affect hearts.
For the patients with serious swelling, they should restrict the water and sodium consumption and use diuretic as well as limit protein intake.

As the underlying cause of swelling is the kidney damage, they should restore the kidney structure firstly to improve the renal function.
