A study by Stafford et al. (2017) looked at the relationship between the activation patterns of specific pelvic floor muscles and incontinence in men following prostatectomy (surgical removal of the prostate gland).
It was found that "poor function of the bulbocavernosus* and puborectalis* muscles could be compensated by good striated urethral sphincter* function, but the bulbocavernosus and puborectalis muscles had less potential to compensate for poor striated urethral sphincter function." (* these names are of specific muscles within the male pelvic floor)
This study does not show that intervention targeted at improving striated urethral sphincter muscle function would necessarily change activation patterns and therefore continence. It purely shows that different activation patterns exist between continent and incontinent men.
The only way to assess the particular components of the male pelvic floor is the use of transperineal ultrasound. This is the use of ultrasound placing the transducer head over a man's perineum (the area between his genitals and anus) to get a view of the pelvic floor muscles up towards the bladder. Transperineal ultrasound allows for the multiple muscles within the pelvic floor to be visualised simultaneously in real-time (Stafford et al. 2012).

There have even been studies which have shown that different verbal cues can influence the activation patterns within the pelvic floor (Stafford et al. 2015).
So for incontinent men following prostatectomy, transperineal ultrasound allows for assessment of the individual muscle actions within the pelvic floor and potentially for assisting with training these muscles (watch this space for more scientific evidence in the future).
