[The effect of radiotherapy on the state of the intestinal flora in urologic cancer patients].

In radiotherapy of patients with prostate carcinoma the microflora of the intestine and its dynamics were studied. The mostly older patients with chronic affections of the digestive tract showed a considerable injury in composition of intestinal microflora. The radioeffects on regions of minor pelvis are accompanied by acute radioreactions and a chronic radiogenic intestinal syndrome that deteriorates the existing disorders of quantitative and qualitative composition of intestinal microflora considerably what, on its part, contributes to maintenance of the pathological process in intestine. In addition to therapeutic remedies to suppress radioreactions on intestine therefore it is appropriate to apply preparations that affect the composition of intestinal microflora in a normalizing manner.
