Key clinical point: Although voiding trials may detect similar rates of dysfunction regardless of whether voiding occurs spontaneously or after the bladder is retrograde filled with saline, retrograde-fill trials take less time.

Major finding: The rate of failed voiding trials did not significantly differ between groups. The rate was 12.7% in the retrograde-fill group versus 7.7% in the spontaneous trial group. Those who underwent retrograde fill reported significantly greater satisfaction with their method of voiding evaluation, however, compared with patients whose voiding trials occurred spontaneously.

Study details: A randomized, prospective study of 109 patients.
