title: [Clinical morphological characteristics of epithelial bladder tumors].
abstract: Under study were the clinico-morphological features of epithelial tumors of the urinary bladder in 1452 patients subjected to surgery. There were differentiated three main clinico-anatomical forms of the tumor and its variants: exophitic (87.4%), endophitic (5.5%) and mixed--exophitic-endophitic ones (7.1%). The frequency and terms of recurrence were dependent on the clinico-anatomical form and stage of the tumor and its morphology. The frequency of recurrence of high-differentiated forms of the tumor made 26.9 +/- 3.0%, in low-differentiated and metaplastic forms--45--46%, in anaplastic cancer--62.8% +/- 15.4%.
