Clinical Analysis of 45 Cases of Pheochromocytoma

A retrospective analysis of clinical data of 45 cases of pheochromcytoma was presented. The diagnosis was confirmed by biochemical measurement or pathobiological examination. The tumours were located in adrenal medullae in 31 cases, in extre-adrenal sympathetic chain in 10cases and in urinary bladder in 4. Tumours were benign in 41 cases and malignant in 4 cases, 8 cases were normotensive, while the others were predominantly hypertensive. Patients with bladder pheochromocytoma all showed haematuria. The elevation of urinary catecholamine was consistent with that of VMA in generia. A positive correlation was found between blood picture and urinary biochemical findings. The detection rate of CT scanning （92%） was higher than that of echography （82%） or retroperioneal pneumography （75%）. 41 patients had been operated on, with a short-term curative (effect of 87.5% and a long-term follow-up care rate of 80%.
