Hypothesis / aims of study
Introduction. Lack of pelvic floor muscles (PFM) relaxation in women is the reason for dysfunctional voiding (DM) symptoms: difficult “start”, interrupted or weak stream, incomplete empting. Biofeedback (BFB) in the relaxation mode is often used as the first line treatment demonstrating good results. In cases when BFB has no or low effect botulinum toxin type A (BTA) injections into PFM can be used as the next line treatment.
Aim of study. To evaluate the clinical efficiency of BFB after BTA therapy in women with DV which had no effect at the first line BFB treatment.
Study design, materials and methods
The results of treatment of 140 women age 22 – 65 were analyzed. The diagnoses of DM was confirmed by urodynamics. BFB in the relaxation mode was conducted as the first line therapy. The treatment was effective in 102 women (64%), and not effective in 58 (36%). At the second line patients with no effect of BFB (N=58) were injected with BTA into PFM (100 Uts). 6-12 months later when BTA effect decreased and “obstructive” symptoms came back another BFB series was conducted.
Interpretation of results
The summarized effectiveness was 48,3%
