Eight hours of hypotensive versus normotensive resuscitation in a porcine model of controlled hemorrhagic shock.

Objectives: The aim of this study was to compare hypotensive and normotensive resuscitation in a porcine model of hemorrhagic shock.

Methods: This was a prospective, comparative, randomized survival study of controlled hemorrhagic shock using 28 male Yorkshire-Landrace pigs (15 to 25 kg). In 24 splenectomized pigs, the authors induced hemorrhagic shock to a systolic blood pressure (sBP) of 48 to 58 mm Hg (approximately 35% bleed).

Management of rectal injuries sustained during laparoscopic radical prostatectomy.

Objectives: To report on a treatment algorithm for the management of rectal injures. Rectal injuries during laparoscopic radical prostatectomy (LRP) are rare. In the first 200 cases of LRP performed at our institution, 2 (1%) rectal injuries occurred.

IL-6 does not predict current urolithiasis in stone formers.

Introduction: Interleukin-6 (IL-6), an inflammatory marker, has previously been found to be elevated in the urine of patients with urolithiasis. Oxalate and other stone precursors have been shown to increase IL-6 production in proximal tubular epithelial cells in vitro. We examined whether urinary IL-6 could be used as a screening test to determine current urolithiasis in individuals who are known to form urinary stones.

Usefulness of urinalysis in following patients with distal ureterolithiasis.

Purpose: The determine the usefulness of urinalysis in monitoring patients with distal ureterolithiasis.

Materials And Methods: Patients with microhematuria who were found to have a distal ureteral stone and who were candidates for conservative management were enrolled in the study. Patients were typically seen in clinic at 1 to 2 weeks after initial diagnosis and reassessed.
