Role of Radiofrequency (Votiva, InMode) in Pelvic Floor Restoration

Postpartum pelvic floor disorders are estimated to impact 24% of women in the United States. This study describes the use of a radiofrequency device (Votiva, InMode) for postpartum pelvic floor restoration using an electrostimulator to objectively measure treatment effect.

A retrospective evaluation was conducted between April 2017 and May 2018 of consecutive patients undergoing vaginal radiofrequency treatment. Inclusion criteria were patients at least 6 weeks postvaginal delivery with symptoms of pelvic floor dysfunction. Resting pelvic floor muscle tone and maximal pelvic floor contraction were measured.

Fifty women were included in the study with an average age of 32 (29-40) years old, average of 2.6 pregnancies, and 1.8 vaginal deliveries. Two patients were lost to follow-up and excluded. Three complete radiofrequency treatments were performed in 31/50 patients, whereas 19 patients received 1-2 treatments. There were no adverse events from the radiofrequency treatment. No changes were found in resting pelvic muscle tone after Votiva treatment [Wilks' lambda = 0.98, F (1, 45) = 0.86, P = 0.36]. The quantity of treatments seemed to impact mean values of maximal pelvic floor contraction [F (1, 45) = 105.14, P < 0.001]. On the patient questionnaire, patients felt subjective improvement correlated to number of treatments.

Radiofrequency is safe for the treatment of pelvic floor dysfunction. This study showed no changes in resting pelvic muscle tone but an improvement in maximal pelvic floor contraction. A prospective randomized study is being conducted to further evaluate the efficacy of this technology.
