Current treatments for patients with stress urinary incontinence.

Stress urinary incontinence (SUI) has been defined as the complaint of involuntary leakage of urine on effort, exertion, sneezing or coughing (Abrams et al, 2002). It becomes known as urodynamically proven stress incontinence (USI) when filling cystometry (a test of bladder function) shows a rise in intra-abdominal pressure, without a detrusor muscle (bladder muscle) contraction, causing urine loss via the urethra.
