title: Urodynamic study of 15 patients with postmicturition dribble.
abstract: Fifteen patients presenting with postmicturition dribbling as their only symptom were studied in the urodynamic laboratory. Seven of these patients had no urodynamic abnormality but left a significant bulbar residue after micturition. Five patients had normal detrusor function but failed to milk back contrast from the prostatic urethra during voluntary interruption of the steam. Two of these also had a small amount of bulbar residue. The remaining three  had unstable detrusor function. One had classic bladder neck obstruction. One had a bulbar residue and the other failed to milk back properly. Despite the various mechanisms for postmicturition dribble, the management is the same in all cases. The patient is instructed to press the bulbar urethra manually in the perineum after micturition and evacuate the residue, and symptomatic relief is almost always obtained. Urodynamic studies in these patients are not justified unless this maneuver fails to alleviate the symptoms.
