Nine patients with urachal tumors have been reevaluated. There were 5 men and 4 women, whose ages ranged from 6 to 72 years. Surgery was performed in 4 cases, radiotherapy was used in 2 cases, and the remaining 3 cases were judged to be beyond therapeutic help. Three years after treatment, also all cases subjected to therapy were dead. The diagnostic delay, the inadequacy of treatment, and therefore the absolutely unfavorable prognosis of these tumors are discussed.
