Chronic Renal Failure is a disease affecting the kidneys, in which there is a gradual decline in kidney function and urine output over time. Mild kidney disease can lead to increased blood pressure and frequent urination at night. Moderate disease can lead to mild anemia and increased risk of heart attacks, strokes and other diseases. However, severe decline in kidney function leads to excessive retention of waste products in the body (a condition called "uremia"), for which heamodialysis or peritoneal dialysis is necessary. Kidney failure is a serious disease, and all affected patients should be under the supervision and treatment of an experienced and qualified Urologist.
