Effect of cardiopulmonary bypass on urethral blood flow as measured by laser Doppler flowmetry.

Abstract

PURPOSE Previous reports have implicated urethral ischemia as a potential predisposing factor for the increased incidence of urethral strictures after cardiac bypass surgery. These reports were based on indirect measurements of urethral blood flow. We directly measured and compared urethral perfusion before and during cardiopulmonary bypass. MATERIALS AND… (More)
