Chronic purulent coxit complicated by necrosis of the head of the femur and the formation of a fistula: 1 - control x-rays (up to fistulografii); 2 - fistulogram.

Fistulography is the method of roentgenologic examination fistular moves by filling their contrasting substance with the subsequent x-rays (Fig.). The main task of fistulography a detailed examination of the nature and direction of fistulous moves and their branches, as well as the presence or absence communications between fistulous courses and areas of destruction (in particular in the bones) and foreign bodies, sequesters, abscesses and other cavities located in the nearby with fistulous move the bodies. Contrast x-ray abscess cavity is called abscessography.
As contrast agents in fistulografii usually use oil solutions of organic compounds of iodine (yodolipola, lipiodol) or its water-soluble compounds (diodon, detract, cardiotest, urographine and so on). With a wide fistulous passages, of which the contrast agent may be easily removed after fistulografii, are oil and water suspensions chemically pure barium sulfate.
Before fistulography produce overview of the control and x-ray study area, in two mutually perpendicular planes. Then the outer edges of fistulous holes grease 5 - 10% alcoholic iodine solution and by using a syringe to suck the contents of the fistula, then enter the contrast agent, the pre-warmed to body temperature. If the procedure is painful, it should be under local anesthesia. Having achieved tight as possible filling of fenestration moves (without the use of rude pressure), clamp fistulous hole gauze ball, remove the syringe cannula and quickly cover the hole with a gauze ball sticky plaster or kleola. Then produce x-rays in the necessary projections, identify the location of fistulous moves, then open the outer opening of the fistula and free fistula from the contrast medium by sucking, and if that were not enough, by washing izotoniceski solution of sodium chloride, 2% a solution of soda or sterilized water.
