139例单侧肾切除患者进行了长期随访1～57年,平均为13.0±1.1年,男82例,女57例,由于肾输尿管肿瘤而行1侧肾切除52例,由于肾结核43例,其他疾病44例,随访中侧量患者的血压,测定肾功能:抽血测肌酐,电解质和β_2微球蛋白清除率,NAG和蛋白的排泄量,结果显示血清肌酐浓度及其清除率,β_2微球蛋白清除率,血压都保持稳定,甚至57年后仍然稳定,这说明遗留肾的功能得以很好地保存。肾功能水平与肾切除后的年限和肾切除的原因无关,但与肾切除时的年龄有关,肌酐清除率与肾切除时年龄成反比,原因很清楚,青年人肾代偿性生长快,而老年人则缓慢。尿NAG排泄在肾切除超过20年的病人中高于未
139 patients with unilateral nephrectomy for a long-term follow-up of 1 to 57 years, an average of 13.0 ± 1.1 years, 82 males and 57 females, due to renal ureteral tumors and 1 case of renal resection in 52 cases, due to renal tuberculosis in 43 cases, 44 cases of other diseases were followed up for measuring the blood pressure of patients with renal side effects: blood creatinine, electrolyte and β 2 microglobulin clearance, NAG and protein excretion were measured. The results showed serum creatinine concentration and clearance, β_2 micro Globulin clearance, blood pressure remained stable, and even 57 years after the stable, indicating that the function of the left renal can be well preserved. The level of renal function has nothing to do with the age of nephrectomy and the cause of nephrectomy, but it is related to the age at nephrectomy. The rate of creatinine clearance is inversely proportional to the age at nephrectomy. The reason is clear. Young people have fast compensatory growth, Older people are slow. Urinary NAG excretion was higher in patients with nephrectomy than 20 years
