The treatment of chronic renal failure primarily requires identifying the cause and treating it accordingly. Chronic renal failure refers to the state in which various diseases damage the kidneys, leading to the destruction of kidney tissue and resulting in the kidneys' inability to adequately excrete metabolic waste, causing an accumulation of such wastes in the body. There are no medications that can directly affect the kidneys, regenerate kidney tissue, and restore kidney function. Currently, medicine cannot achieve this, and there are no specific drugs for the treatment. Therefore, the treatment of chronic renal failure focuses on treating the primary disease to slow the progression of renal failure. For example, chronic renal failure caused by diabetes necessitates the use of insulin to control blood sugar, while patients with hypertension need to use antihypertensive drugs.

Is stage five chronic kidney failure serious?

Strictly speaking, there is no condition called "chronic renal failure stage five," but there is a term "chronic kidney disease stage five." Chronic kidney disease is divided into five stages based on the glomerular filtration rate (GFR). Stage five chronic kidney disease indicates that the patient's GFR is less than 15 milliliters per minute, which is about 15% of normal kidney function and is essentially equivalent to uremia. Therefore, chronic renal failure or chronic kidney disease stage five is very dangerous and can cause many complications. Moreover, this type of kidney failure is irreversible and incurable, and the patient may need to undergo dialysis or a kidney transplant.

Can patients with chronic renal failure have sexual intercourse?

Patients with chronic renal failure can have sexual intercourse, but there are prerequisites. Since sexual activity is physically demanding and requires adequate cardiopulmonary function, patients can engage in sexual activity if they do not experience chest tightness or shortness of breath and their blood pressure is well controlled. If there are no obvious symptoms of fatigue, difficulty breathing, or chest tightness during sexual activity, there should be no significant problems. However, since the patients have chronic renal failure, it is advisable to avoid conception unless prepared for pregnancy. Pregnancy can further burden the kidneys in female patients and potentially exacerbate chronic renal failure. Male patients with chronic renal failure may be taking medications that could affect sperm quality. Therefore, contraception should be practiced unless preparations have been made.

Why does chronic renal failure cause vomiting?

Patients with chronic renal failure who experience vomiting generally indicates that their condition has become very severe. Typically, from stage four of chronic kidney disease onwards, a large amount of metabolic waste accumulates in the body, and patients may have severe metabolic acidosis, among other issues. These conditions can cause edema of the gastrointestinal mucosa, and these metabolic wastes can also irritate the gastrointestinal tract, leading to symptoms like nausea, vomiting, and loss of appetite. Of course, besides these reasons, other gastrointestinal diseases such as chronic gastritis, gastric ulcers, and even gastric cancer should also be ruled out.

What should I do about edema from chronic renal failure?

Chronic renal failure often leads to edema, which is a common symptom associated with the decreased ability of the kidneys to excrete water, resulting in significant water retention in the body. There are two treatment options for this disease. First, medication can be used, typically diuretics such as loop diuretics. After administration, the patient's urine output increases, which can help reduce edema. Second, for patients who do not respond well to medication, and in cases where edema leads to heart failure or pulmonary edema, dialysis treatment may be considered. Through dialysis ultrafiltration and dehydration, edema can also be alleviated.

Principles of Treatment for Chronic Renal Failure

The principles of treatment for chronic renal failure include early-stage non-dialysis conservative treatment as well as end-stage renal replacement therapy. Non-dialysis conservative treatment includes delaying the progression of kidney damage, which requires treating the primary disease, implementing nutritional support, and controlling factors that accelerate kidney disease progression, such as controlling high blood pressure, proteinuria, and hyperlipidemia. Additionally, it is necessary to eliminate metabolic waste from the body, and maintain the body's water, electrolyte, and acid-base balance. Renal replacement therapy includes hemodialysis, peritoneal dialysis, and kidney transplant therapy.
