Pelvic floor muscle exercise with biofeedback helps regain urinary continence after robot-assisted radical prostatectomy.

BACKGROUND

To determine the benefit of pelvic floor muscle exercise with visual biofeedback on promoting patient recovery from incontinence, we investigated variables associated with the early restoration of continence for patients who underwent robot-assisted radical prostatectomy.

METHODS

Of the 83 patients enrolled, 41 consecutive patients completed pelvic floor muscle exercise (the exercise group), and the other 42 consecutive patients just before the pelvic floor muscle exercise program commenced (the control group). The primary outcome was whether pelvic floor muscle exercise engagement was associated with zero pad continence restoration within 3 months of surgery.

RESULTS

Continence restoration percentages (defined as zero pads used per day) at 1, 3, and 6 months after surgery were 49.4%, 77.1%, and 94.0%, respectively. The exercise group achieved significantly higher recovery rates at 1 month (p=0.037), 3 months (p<0.001), and 6 months (p=0.023). Cox regression analysis demonstrated that a lower Gleason score (<8; hazard ratio, 2.167), lower prostate specific antigen (<20 ng/dL; hazard ratio, 2.909), and engagement in pelvic floor muscle exercise (hazard ratio, 3.731) were independent predictors of early recovery from postprostatectomy incontinence. Stratification by age showed that those younger than 65 years did not benefit significantly from exercise (log-rank test, p=0.08), but that their elderly counterparts, aged 65-70 years (p=0.007) and >70 years old (p=0.002) benefited significantly.

CONCLUSION

This study suggests that postoperative engagement in pelvic floor muscle exercise with biofeedback speeds up the recovery of continence in elderly patients (≥65 years old) that undergo robot-assisted radical prostatectomy.
