Purpose: To determine the effect of reduced radiation (tube charge, measured as milliamperes per second) protocols on the sensitivity and specificity of multidetector computed tomography (CT) in the detection of renal calculi.
Materials And Methods: This Health Insurance Portability and Accountability Act-compliant human cadaveric study was approved by the Department of Anatomic Pathology with strict adherence to the university policy for handling donor specimens. Three to five renal stones (range, 2.
Purpose: We determined the effect of reconstructed section width on sensitivity and specificity for detecting renal calculi using multidetector row computerized tomography.
Materials And Methods: Three to 5 renal stones 2 to 4 mm in size were randomly placed into 14 human cadaveric kidneys and scanned by 16-row detector computerized tomography at 1.25 mm collimation and identical scanning parameters.
Purpose: Previous attempts to correlate preoperative patient characteristics with operative complexity and operative time prior to laparoscopic donor nephrectomy have found few consistent relationships. The purpose of this study is to determine the effect of abdominal and perirenal fat measured with preoperative computerized tomography (CT) upon subsequent operative time and complexity during hand-assisted laparoscopic donor nephrectomy.
Materials And Methods: A retrospective chart, database, and CT angiogram review was conducted on 103 consecutive patients who underwent a hand-assisted laparoscopic donor nephrectomy.
Purpose: The merits of laparoscopic sealing devices have been poorly characterized. The purpose of this study was to compare two bipolar sealing devices [LigaSure V (LS) and Gyrus PK (GP)], an ultrasonic device [Harmonic Scalpel ACE (HS)] and a novel device using nanotechnology [EnSeal PTC (ES)].
Materials And Methods: The ability of all four 5 mm devices to seal 5 mm bovine arteries was tested under controlled temperature and humidity in accordance with manufacturer specifications.
Article Synopsis
- - The study compared a new balloon expandable ureteral access sheath to a conventional one in pigs, focusing on insertion force, flow rate, and urothelial damage.
- - Results showed the novel sheath required significantly less force to insert and had a higher saline flow rate, while also causing less damage to the ureteral lining.
- - The research concludes that the new sheath is a promising alternative for ureteral access, and a clinical trial is underway to further investigate its benefits.
Background And Purpose: Prior research has demonstrated that counterintuitive laparoscopic surgical skills are enhanced by experience with video games. A similar relation with robotic surgical skills has not been tested. The purpose of this study was to determine whether prior video-game experience enhances the acquisition of robotic surgical skills.
