[Epithelial tumors of the urinary bladder in the first twenty years of life (author's transl)].

Eighty two cases of epithelial tumors of the bladder in the first two decades of life have been reviewed from the literature. A case of a transitional cell carcinoma, grade I--II, in a 16-year-old boy is presented. Transurethral electroresection was done and there was no recurrence, two years postoperatively. In 70% of all cases a hematuria was found. The epithelial bladder tumors in children have a better prognosis, a lower tendency to recur and a lower grade malignancy than tumors in adults. Treatment of choice is transurethral or suprapubic tumor excision without drug chemotherapy or radiation therapy.
