renal(redirected from renal capsular cyst)
Also found in: Dictionary, Thesaurus, Encyclopedia.
Acute renal failure may be classified as: prerenal, associated with poor systemic perfusion and decreased renal blood flow; intrarenal, associated with renal ischemia or toxins; or postrenal, resulting from the obstruction of urine flow out of the kidneys.
oliguria is the hallmark of tubular necrosis, but it is not always present. Other symptoms besides a marked decrease in urinary output are related to fluid and electrolyte imbalances, anemia, hypertension, and uremia. In addition to supportive measures to restore and maintain a tolerable internal environment during acute renal failure, it may be necessary to remove toxic wastes by hemodialysis or peritoneal dialysis.
Causes of renal failure are many and can be roughly divided into three groups: (1) those that directly affect the kidney by infection, inflammation, and upper urinary tract obstruction; (2) those in which there is an obstruction of the lower urinary tract; and (3) systemic diseases and toxicities, such as hypercalcemia, hypertension, disseminated lupus erythematosus, atheroma, and diabetes mellitus.
Symptomatic relief of the many manifestations of end-stage renal disease is a challenge to every member of the health care team. Virtually every system within the body is adversely affected in some way. Pathophysiologic changes involve the gastrointestinal tract, the skin, the cardiovascular system, the lungs, bone, and blood, and the metabolism of glucose and protein.
Hemodialysis or peritoneal dialysis may be employed to rid the body of wastes that the kidney can no longer handle. For some patients transplantation of a human kidney is a viable alternative to continuous dialysis. Others who cannot withstand surgery and long-term immunosuppression are not good candidates for a kidney transplant.
