Comparison of dynamic features of pelvic floor muscle contraction between men with and without incontinence after prostatectomy and men with no history of prostate cancer.

Men who were continent postprostatectomy achieved greater shortening of the SUS, PR, and BC muscles than incontinent men during voluntary contractions and demonstrated better PR and BC function than control participants during coughing. The capacity to shorten the SUS ≥4.1 mm and the PR ≥2.4 mm best distinguished between PPI and PPC and might be a useful clinical target for conservative treatment programs.
