Inter- and Intraobserver Agreement in Measuring Urolithiasis Density on Nonenhanced Computed Tomography.

Treatment choice for urolithiasis is partially based on measuring stone density in HU on nonenhanced computed tomography (NECT). Interobserver variability in these measurements could have treatment consequences. This study aims to assess the observer agreement of measuring HU and whether the use of a protocol leads to a better agreement.

Semiautomatic sizing software in emergency endovascular aneurysm repair for ruptured abdominal aortic aneurysms.

Purpose: In emergency endovascular repair (EVAR) of ruptured aneurysms of the aorta (rAAA), anatomical suitability must be determined. Semiautomatic three-dimensional assessment of the aortoiliac arteries has the potential to standardise measurements. This study assesses the fitness for purpose of such a semiautomatic approach for rAAA and determined interobserver agreement on suitability.

Endovascular repair versus open repair of ruptured abdominal aortic aneurysms: a multicenter randomized controlled trial.

Objective: Randomized comparison of endovascular repair (EVAR) with open repair (OR) in patients with a ruptured abdominal aortic aneurysm (RAAA).

Background: Despite advances in operative technique and perioperative management RAAA remains fraught with a high rate of death and complications. Outcome may improve with a minimally invasive surgical technique: EVAR.
