Introduction: The effect of biofeedback for pelvic floor muscle training (PFMT) on the recovery of post-prostatectomy urinary incontinence (PPI) is still controversial. We performed a randomized controlled trial to investigate the effectiveness of a novel personalized extracorporeal biofeedback device (Anykegelâ„¢, Figure 1) for PFMT on PPI after robot-assisted laparoscopic radical prostatectomy (RARP).
Methods: A total of 84 patients who underwent RARP were randomized either to the intervention group (42) (receiving biofeedback-PFMT using a novel device [Anykegelâ„¢] in addition to verbal and written instruction) or the control group (42) (Figure 2). Patients were evaluated 1, 2, and 3 months after surgery. Incontinence severity was measured by the 24-h pad test. The International Prostate Symptom Score (IPSS) and the International Index of Erectile Function (IIEF-5) questionnaire were also assessed.
Results: Regarding the average urine loss in the 24-h pad test, the intervention group showed significantly smaller volume of urine loss at the 1 month follow-up than the control group (71.0g vs. 120.8g, respectively, p = 0.028, Table 1). However, from the 2 month follow-up visit, no significant differences were observed between the two groups. In addition, in the 1 month follow-up data of the IPSS-total score, the intervention group demonstrated significantly favorable changes from baseline with improved scores compared to the control group (0.25 Â± 9.15 vs. -3.81 Â± 8.98, respectively, p = 0.046).
Conclusions: The personalized extracorporeal biofeedback device (Anykegelâ„¢) for PFMT offers a significant positive effect on the recovery of PPI after RARP, especially in the early postoperative period.
