SPONTANEOUS VOIDING IS SURPRISINGLY RECOVERABLE VIA OUTLET PROCEDURE IN MEN WITH UNDERACTIVE BLADDER AND DOCUMENTED DETRUSOR UNDERACTIVITY ON URODYNAMICS

AIMS: To identify clinical and urodynamic factors leading to spontaneous voiding in men with detrusor underactivity (DU) and suspected bladder outlet obstruction who underwent an outlet de-obstruction procedure. METHODS: We identified 614 men who underwent an outlet procedure at our institution from 2005 to 2014. Men were stratified by bladder contractility index (BCI). The primary outcome was spontaneous voiding after surgery. Data were analyzed in Statistical analysis system software. RESULTS: Of the 131 men who underwent preoperative urodynamics, 122 (mean age 68 years) had tracings available for review. DU (BCI   40 (OR = 5.595; 95% CI = 1.685-18.575). CONCLUSION: Outlet de-obstruction improves spontaneous voiding in men with DU and may benefit men who do not meet the urodynamic threshold for obstruction.
