Tumour weight was compared with maximal vanillylmandelic acid and catecholamine excretion in 24-hour urine in 21 patients with phaeochromocytoma. The tumour weight correlated both with vanillylmandelic acid (r = 0.805, P less than 0.001) as well as urinary catecholamine levels (r = 0.725, P less than 0.001). Normal vanillylmandelic acid excretion was found in seven patients; urinary catecholamine levels were abnormal in all patients. The Katecult test was additionally performed in ten patients, with nine positive results.
对21例嗜铬细胞瘤患者的肿瘤重量与24小时尿中香草扁桃酸和儿茶酚胺的最大排泄量进行了比较。肿瘤重量与香草扁桃酸（r = 0.805，P<0.001）以及尿儿茶酚胺水平（r = 0.725，P<0.001）均相关。7例患者香草扁桃酸排泄正常；所有患者尿儿茶酚胺水平均异常。另外对10例患者进行了凯特库尔特试验，9例结果为阳性。
