Nonenhanced CT has a higher sensitivity for the detection of ureteral calculi compared with US.

By using a low-milliampere technique and the quick-check method, CT fluoroscopic time and radiation exposure can be minimized.

For the treatment of iatrogenic femoral pseudoaneurysms, thrombin injection under sonographic guidance is a quick and effective method of therapy. Failures and complications are infrequent. At our institution, sonographically guided thrombin injection has replaced compression repair.

For the treatment of iatrogenic femoral arterial pseudoaneurysms, thrombin injection with US guidance appears to be superior to compression repair.
