Stress urinary incontinence (SUI) frequently compromises the female quality of life and risk factors include Caucasian ethnicity, parity, obesity, smoking, caffeine abuse, and medications.1-3 Common types of urinary incontinence are: SUI (involuntary loss due to pressure exerted on the pelvic floor, exercise, coughing or sneezing); urge incontinence (loss associated with intense urge to urinate); and mixed (concomitance of two types).2 Estimated prevalence of incontinence is 35.1% in women of 19-90 years, 76,2% of which are SUI.3 Normal stimulation of estrogen receptors at the lower urinary tract increases the pressure on the urethral mucosa and urine continence; but old women with lower estrogen levels have shorter urethra, decreased bladder capacity and closing pressure, besides more detrusor contractions.
