RETROVESICAL TUIMOR (UNDIFFERENTIATED TRANSITIONAL CELL CARCINOMA): REPORT OF A CASE

Abstract

A 29-year-old man was hospitalized with the complaints of lower abdominal mass, miction pain and disturbance of bowel movement. A child-head sized, elastic hard, uneven surfaced and non tender mass was palpated in the lower abdominal region on physical examination. The prostate and seminal vesicles were normal on the rectal examination. Roentgenogram, cystoscopy and romanoscopy suggested retrovesical tumor. The tumor was removed, but right ureterovesiconeostomy and rectal pull-through operation were needed. Pathological diagnosis was undifferentiated transiticnal cell carcinoma. We presented a clinical and pathological survey of 90 cases of retrovesical tumor (sarcoma: 44 cases, other malignant tumor: 11 cases, benign tumor: 35 cases).
