Change in urethral pressure during voluntary pelvic floor muscle contraction and vaginal electrical stimulation

Abstract

The purpose of the study was to compare the effect of voluntary pelvic floor muscle (FFM) contraction and vaginal electrical stimulation on urethral pressure. Twelve women with genuine stress incontinence, mean age 49.4 years (range 33-66) participated in the study. The urethral and bladder pressures were recorded simultaneously through a double-lumen 8 Ch catheter. The patients first performed three voluntary PFM contractions. Then two electrical stimulators, Conmax and Medicon MS 105, 50 Hz, were used in random order. A visual analog scale was used to measure pain and discomfort. Pain was reported to mean 6.8, SEM 0.64 (range 0.7-9.9) and mean 6.1, SEM 0.81 (range 0-9.1) with Conmax and Medicon MS 105, respectively. The mean paired difference in favor of voluntary contraction with Conmax was -8.0, SD 6.7, P = 0.0067, and with Medicon MS 105 it was -12.2, SD 5.9, P = 0.0022. The results demonstrated that voluntary PFM contraction increased urethral pressure significantly more than did vaginal electrical stimulation.

Evidence for benefit of transversus abdominis training alone or in combination with pelvic floor muscle training to treat female urinary incontinence: A systematic review

“…The muscle fibers pass medially and posteriorly to insert variously into the midline organs, the puborectalis (pubovisceral muscle) behind the rectum into its partner, with iliococcygeus inserting into the ano-coccygeal raph e. The PFM form a ''U'' shaped sling around the urethra, vagina and anus and a contraction of the muscles has a direct influence on the urethra because they compress the urethra, thereby increasing the urethral pressure. [9][10][11][12] In addition, the striated sphincter muscles of the urethra and the PFM act together with a PFM contraction. 13 The PFM also play an important role in maintaining adequate pelvic support, ensuring the optimum position of the bladder, uterus and rectum.…”
