Clinical and urodynamic evaluation of women with detrusor instability before and after functional pelvic floor electrostimulation.

ABSTRACT

Detrusor instability is the second most frequent cause of female urinary incontinence. There are many therapeutic options, including non-invasive and surgical procedures. In this study, we evaluated the effects of pelvic floor vaginal electrostimulation using equipment designed in our institution, over three consecutive months, for treatment of 29 women with detrusor instability. After treatment 22 patients (76%) considered themselves cured or symptomatically improved; seven patients (24%) had no change in symptoms after therapy. There was objective cure and improvement in ten (34.5%) and in eight (27.5%) patients, respectively, and the urodynamic parameters did not change in 11 patients (38%). Electrical stimulation resulted in a gradual decrease in the number of urinary leakage episodes and increase in maximum cystometric capacity in first desire to void and in urinary volume.
