Electrolytes, BUN, creatinine: who's at risk?

Electrolytes, BUN, and creatinine are some of the most frequently ordered laboratory tests. The use of these tests in emergency practice has not been studied critically, and few investigations of their use in other disciplines have been performed. A review of the available literature and an analysis of medical problem solving, costs, and complications is presented.

Ultrasonography and computed tomography in severe urinary tract infection.

A prospective study evaluated the utility of renal computed tomography (CT) and ultrasonography in 35 patients hospitalized for treatment of urinary tract infection. Renal computed tomograms were abnormal in 18 of 28 patients with acute pyelonephritis and three of four patients with urosepsis, showing findings consistent with pyelonephritis in 17 patients and intrarenal abscess or focal bacterial nephritis in four patients. Renal sonograms were abnormal in only eight patients, showing findings compatible with pyelonephritis in four and intrarenal abscess or focal bacterial nephritis in the other four.
