Withgreat dilution of a small amount of injected solution either MECHANICAL DILATATIOxV 121 a diffuse round outline or but a few dim, scattered shadowsare visible to suggest the distended sac. At times but asingle dilated calyx may be outlined, due to the fact thatthe injected fluid has remained undiluted in a partiallydrained calyx. In Fig. 90 the outUne of a large hydro-nephrotic sac is visible with the detached areas of greatlydistended calyces. The ureter is seen to bend acutely upon.
