title: Computed tomography appearance of the Lapra-Ty and Weck hem-o-lok clips in patients who recently underwent laparoscopic urologic surgery.
abstract: The nonmetal suture securing Lapra-Ty clip (LTC) and vessel ligating Weck hem-o-lock clip (WKHL) are useful tools for the laparoscopic surgeon. We report the postoperative computed tomography (CT) scan appearance of these clips. The CT imaging of patients who underwent urologic surgery demonstrate the WKHL and LTC to be radiopaque. Urologists and radiologists should be aware of the radiographic appearance of the LTC and WKHL given the ease with which they could be confused with urinary lithiasis when applied near the urinary system.
