METHODS In our analysis 16 male patients with no history of urinary incontinence or obstructive voiding dysfunction were included. We analyzed visible interaction between bladder, urethra and the pelvic floor during Valsalva maneuver as well as before and during voiding via real time MRI. Mean age was 69.8 years (range 52-79 years). Mean prostate volume was 33,1 ccm (range 18-69 ccm). One Patient was not able to void during real-time MRI. Two patients had little residual urine. The axis bladder neck to pubococcygeal (PC) line and the angle between os pubis (OP) and the axis bladder neck was measured before and at the end of voiding. Additionally the angle between os pubis (OP) and the axis bladder neck was measured while performing Valsalva maneuver. RESULTS Before voiding, the axis bladder neck to PC line was 0 to +17 mm (median +11mm). At the end of voiding, the axis bladder neck to PC line was +9 to +27 mm (median +21mm). The angle between os pubis and the axis bladder neck before micturition was 23 degreess to 48 degrees (median 34 degrees) and at the end of micturition 39degrees to 114 degrees (median 55,5 degrees). In contrast, during Valsalva maneuver, no change of the angle between os pubis and the axis bladder neck could be found. CONCLUSIONS All patients enrolled in our study, showed relaxation of the pelvic floor, followed by descending of the bladder neck. Micturition could not be initiated until the angle between os pubis and the axis bladder neck started tilting. The results of our study presume that a change of the angle between os pubis and the axis bladder neck seems to contribute to the initiation of active micturition.
