Introduction
1. Patients in the compensatory phase may be asymptomatic; however, some may experience fatigue, low back pain, nocturia, or other nonspecific discomforts.
2. In the intermediate stage of chronic renal failure, symptoms such as fatigue and nocturia become more pronounced.
3. In the late-stage uremic phase, acute left heart failure may manifest as dyspnea, orthopnea, and coughing up pink frothy sputum.
Clinical manifestations of chronic renal failure vary across its different stages. Chronic renal failure is divided into five stages: Stages 1–3 represent the compensatory phase, while Stages 4–5 constitute the decompensatory phase.
During the compensatory phase, patients may be entirely asymptomatic. Some individuals experience fatigue, low back pain, nocturia, or other nonspecific discomforts; others may develop anorexia, Kussmaul respiration (deep, labored breathing indicative of metabolic acidosis), or mild anemia. As the disease progresses into the intermediate stage of chronic renal failure, symptoms such as fatigue, nausea, and nocturia become increasingly pronounced.
In the late-stage uremic phase, patients may exhibit signs of acute left heart failure—including dyspnea, orthopnea, and pink frothy sputum—or manifestations of hyperkalemia—such as abdominal distension and bradycardia—or gastrointestinal bleeding (e.g., hematemesis), central nervous system dysfunction, and other life-threatening complications.
