肾绞痛是泌尿系结石常见的并发症之一,本文采用放免分析法对70例肾绞痛患者监测血、尿β_2-微球蛋白(β_2-m),同时测定血肌酐(Cr)水平,以探讨β_2-m在肾绞痛中的临床意义,现报告如下。 资料和方法 一、正常对照组:正常成人50例,年龄18～56岁,平均38岁。无泌尿系结石及肾绞痛发作史。 二、肾绞痛组:70例,年龄17～55岁,平均35岁,均有典型肾绞痛发作史,经B超、静脉肾盂造影、CT等检查,确诊单侧上尿路结石48例,双侧5例,阴性17 Renal colic is one of the common complication of urolithiasis. In this paper, 70 patients with renal colic were monitored for serum and urinary β_2-microglobulin (β_2-m) and serum creatinine (Cr) level by radioimmunoassay. To explore the clinical significance of β_2-m in renal colic, are as follows. Materials and Methods First, the normal control group: 50 cases of normal adults, aged 18 to 56 years, mean 38 years. No history of urolithiasis and renal colic. Second, renal colic group: 70 cases, aged 17 to 55 years, mean 35 years old, have a history of typical renal colic attack, the B-ultrasound, intravenous pyelography, CT and other tests, diagnosed 48 cases of unilateral upper urinary tract stones , Bilateral in 5 cases, negative 17
