Análisis del volumen rectal en pacientes con cáncer de próstata temprano durante la radioterapia conformada

we realized a study observational, descriptive and quantitative with numeric description of date, we carry out this work to determine the change of rectal volume in 90 patients with diagnostic of prostate cancer during radiant treatment. we utilize conformal radiation therapy technique in tree dimension. the complementary method used to valor the changes in the volume of the rectal was axial computer tomography of the pelvis during the radiation treatment. in 86 % of patients we evidence the rectal blister with fecal and gaseous material the rest 14 % blister was empty. the average of diameters were 23.4 mm to the blister empty and 38.8 mm to the rectal dilated blister, the changes in the rectal volume alter the volume target of the radiation treatment (prostate). recommend do the radiation therapy between the 15 and 18 hours in relation with physiology and practice to all patients a rectal manometer study.
