肾病患者在日常管理中需密切关注多项关键指标，以评估肾功能、控制病情进展并预防并发症。首先，血肌酐（Scr）和估算肾小球滤过率（eGFR）是衡量肾功能的核心指标。eGFR越低，说明肾功能越差；通常eGFR低于60 mL/min/1.73m²持续3个月以上可诊断为慢性肾病。其次，尿蛋白（尤其是尿微量白蛋白或24小时尿蛋白定量）反映肾小球损伤程度，蛋白尿越重，肾脏损害可能越严重。此外，血钾、血钠、血钙、血磷等电解质水平也需定期监测，因为肾功能下降会影响电解质平衡，高钾血症甚至可能危及生命。血压控制同样至关重要，高血压会加速肾功能恶化，建议肾病患者将血压控制在130/80 mmHg以下。最后，血红蛋白和铁代谢指标（如铁蛋白、转铁蛋白饱和度）有助于判断是否出现肾性贫血，这是慢性肾病的常见并发症。综合监测这些指标，有助于医生制定个体化治疗方案，延缓疾病进展，提高生活质量。
Patients with kidney disease should closely monitor several key indicators to assess renal function, control disease progression, and prevent complications. First, serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) are core measures of kidney function. A lower eGFR indicates poorer kidney function; chronic kidney disease is typically diagnosed when eGFR remains below 60 mL/min/1.73m² for more than three months. Second, urine protein—especially microalbuminuria or 24-hour urinary protein excretion—reflects the extent of glomerular damage; higher proteinuria often signifies more severe kidney injury. Additionally, electrolyte levels such as potassium, sodium, calcium, and phosphorus must be regularly checked, as impaired kidney function disrupts electrolyte balance, and hyperkalemia can even be life-threatening. Blood pressure control is equally critical, as hypertension accelerates kidney function decline; patients are generally advised to maintain blood pressure below 130/80 mmHg. Finally, hemoglobin and iron metabolism markers (e.g., ferritin, transferrin saturation) help detect renal anemia, a common complication of chronic kidney disease. Regular monitoring of these parameters enables personalized treatment plans, slows disease progression, and improves quality of life.
