Objective To investigate the diagnosis and treatment of pheochromocytomas in urinary bladder and review relative literatures.Methods The clinical data of 6 cases of bladder pheochroinocytoma were retrospectively analyzed.Bladder submucosal mass was detected by B-ultrasound in 6 cases, computerized tomography(CT)in 4,and cystoscopy in 3.All patients were treated with surgical operation. Results Two patients showed obvious fluctuation of blood pressure during operation.All patients were pathologically diagnosed as pheochroinocytoma postoperatively.Five patients were followed up {from 3 months to 7 years),and their blood pressure returned to normal.No patient had relapse and malignancy. Conclusion Typical hypertension during urination and hematuria constitute the chief symptoms of bladder pheochroinocytoma.B-ultrasound,CT,and cystoscopy are the main methods for the localization of the lesions.Partial cystectomy or excision of the tumor is the preferred management and postoperative long-term follow-up is necessary.
