Thelong axis of each is directed down-wards and outwards. Its antero-external or visceral surface isdirected outwards and forwards,its postero-internal or parietalsurface looking backwards andinwards. Its outer border repre- ■>% x^senting the angle of junction ofits two surfaces is narrow andconvex; its inner border, look-ing obliquely inwards, forwards,and a little downwards, is convexabove and below, but slightlyconcave in its middle third, andfissured by the hilum.

Fig. 181.—Diagram to illustrate the areas to beexamined in radiography of the urinary tract.Tliree exposures are necessary when using thecompressor. A, kidney, B, ureter, C, pelvis. Notethat each area should overlap the one above it if thewhole tract is to be examined. The same procedurehas to be followed for the other side. By using alarger extension tube the whole tract maybe examinedwith three exposures, but in that case the tube mustbe centred over the middle line instead of to eitherside. The dotted circles represent the area covered bythe extension tube in positions A, B, and C. Inregion marked A the compressor is tilted upwards,in B the direction is at right angles to the plate, andin C the compressor is tilted downwards towardsthe feet of the patient. 240 RADIOGRAPHY plane than the upper.
