Fractionated cystography to assess infiltration of the bladder wall by intravesical tumors

Twenty cases of carcinoma of the cervix uteri stage III and IV and ten cases of carcinoma of the rectosigmoid colon stage III were investigated by fractionated cystography to detect any infiltration of the destensible part of the urinary bladder wall. Cystography was normal in all cases except one. The finding was confirmed operatively in each of the ten cases of rectosigmoid carcinoma. This method might be a useful technic for the preoperative assessment of advanced cases of cancer in organs adjacent to the urinary bladder.
