Abstract

PURPOSE: The effect and safety of new intravaginal pelvic floor electrical stimulation, with a distal microchip (PIC16C74), for precision and comfort, in the treatment of female stress, urge and mixed incontinence, were evaluated.
MATERIALS AND METHODS
Thirty-eight incontinent women were divided into three groups: stress incontinence (13), urge incontinence (12) and mixed incontinence (13). Evaluations, both before and after treatment, including history taking, a physical examination, a stress provocation test, a 1-hour pad test, voiding diaries, female lower urinary tract symptom and quality of life questionnaires, were conducted. All patients were treated by pelvic floor electrical stimulation, twice a week, for 6 weeks. The success rate, complications, satisfaction and quality of life were evaluated 1 month later.
RESULTS
The overall success rate was 60.5%. 53.8 (7/13), 66.7 (8/12) and 61.5% (8/13) success rates were found in patients with stress, urge, and mixed type incontinence, respectively. Success rates of 58.8 (10/17) and 55.6% (5/9) were also found in grades I and II, respectively. There were no significant differences in the success rates between the types and grades of incontinence. 73.7% (28/38) of the patients were satisfied with the treatment, and their quality of life improved from 2.4 to 7.2, on the visual analog scales.
CONCLUSIONS
It was concluded that the new intravaginal electrical stimulation, with the microchip (PIC16C74), is an effective and safe treatment for female urinary incontinence, although a longer follow-up period will be required to determine the long term effects.
