Inclusion Criteria:

• >=18 years old
• Signed informed consent form
• Women with urinary stress incontinence defined as follow
• Involuntary loss of urine during increased abdominal pressure. In case of mix urinary incontinence (i.e., stress urinary incontinence associated to urge urinary incontinence) the discomfort related to stress incontinence as evaluated on a 0 (no discomfort) to 100 (maximum discomfort) visual analogic scale is higher for stress incontinence than for urge incontinence symptoms.
• closure pressure between 10 and 60 cm H2O
• the discomfort related to stress incontinence as evaluated on a 0 (no discomfort) to 100 (maximum discomfort) visual analogical scale is higher than 40/100
• Patients never treated with transvaginal electrical stimulation
• Vaginal muscle strength less than 3/5 on the muscular testing
• Positive Pad test (>2 g of leakage measure by pad test with standardised bladder volume)

Exclusion Criteria:

• Patient refusing to sign the consent form
• patient unable to understand or follow the protocol
• inadequate cognitive ability
• patient participating in another research protocol within the 3 previous months
• pregnancy
• women with no contraception
• pacemaker

• urinary incontinence other than stress incontinence
• neurological disease
• permanent metrorrhagia
• ongoing urinary tract infections
• vaginal prolapse > 2
• untreated atrophic vaginitis
• history of surgical treatment for urinary stress incontinence or genital prolapse
