Acute Effect of One Single Application of Intravaginal Electrostimulation on Urodynamic Parameters in Patients with the Overactive Bladder Syndrome

Introduction. We performed this study to quantify the acute effect of one single application of intravaginal electrostimulation in patients with symptoms of the overactive bladder syndrome (OAB), using urodynamic parameters. Materials and methods. Prospectively forty female patients were consecutively selected by entry in two groups: urodynamics only and urodynamics combined with intravaginal electrostimulation. We applied intravaginal electrostimulation with a frequency of 8 Hz, pulse duration of 1000 microseconds and no pulse to rest. Urodynamic evaluations were performed according to ICS standards. Results. By comparing urodynamic measurements in both groups, it appeared that the first sensation of bladder filling, cystometric capacity, micturition volume, urethral pressure, and peak flow showed statistical significant improvement ( P .05 ) during intravaginal electrostimulation. Conclusion. In the present study, we were able to demonstrate an acute effect of one application of intravaginal electrostimulation on bladder function urodynamic parameters in patients with the overactive bladder syndrome. Whether our findings represent the clinical effect of intravaginal electrostimulation in patients with complaints of OAB symptoms needs to be clarified.
