The authors retrospectively reviewed the plain films of 453 surgically proven cases of acute appendicitis, and compared the frequency of several radiographic findings of complicated(n=234) cases to that of uncomplicated(n=219) ones. We found that frequency of radiographic findings in complicated cases is much more common than that in uncomplicated cases: diffusely increased small bowel gas(85.3% vs 24.8%), air fluid level I right lower quadrant(RLQ)(47.0% vs 9.4%), soft tissue mass shadow in RLQ(15.5% vs 0.4%), and appendicolith(5.5% vs none), respectively. Although these plain film findings are not diagnostic perse, they may be helpful in discriminating the complicated cases from the uncomplicated ones.

Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal fenction but can occur with normal renal function, The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease : unilateral ureteral stone(n=3) staghorn calculi(n=2) acute renal failure from sepsis (n=1) renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1) Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter, In 6 patients. injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon. the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of ontrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also

For the evaluation of role of internal pudendal arteriogram in arteriogenic impotence, 70 selective arteriograms of 35 suspected postraumatic impotence patients were analyzed and compared to results of penile bracial index(PBI), duples ultrasonograms of cavernosal artery and cavernosal artery systolic occlusion pressure(CASOP). The results of selective internal pudendal arteriography(SIPA) were classified as 44 cases with normal vascular findings and 26 with abnormal findings. Between two groups, ther was no significant difference in peak velocity and diameter of cavernosal artery in duples ultrasonograms, in pressure difference between systolic pressure of brachial artery and CASOP, and in PBI. These results are also true even in cases with nonvisualization of cavernosal artery casued by complete occlusion of internal pudendal artery. In conclusion, selective pudendal arteriogram is the only one reliable study for the evaluation of arteriogenic impotence, although further study is needed to define the role of other noninvasive approaches.
