Abstract

The efficacy of Crede's maneuver to promote voiding was evaluated prospectively in 207 patients with a variety of lower urinary tract disorders. The normal response to Crede's maneuver was a contraction of the external urethral sphincter (the Crede effect), an increase in urethral pressure and maintained closure of the vesical neck. Relaxation of the external urethral sphincter and synchronous opening of the bladder neck during Crede's maneuver were seen in only 4 patients (2%). We conclude that Crede's maneuver is an inefficient method of bladder emptying in the majority of patients and even when voiding is accomplished with Crede's maneuver it usually is grossly inefficient and associated with significant urethral obstruction.
