Urinary incontinence is defined as involuntary leakage of urine. It happens when pressure in the bladder is higher than that of the muscle (the sphincter) around the urethra.

It is a taboo subject, but also a public health issue, because of the frequency and the socio-economic cost of this handicap. This problem affects hundreds of thousands of patients in industrialized countries, and its impact is constantly increasing, especially due to the aging of the population.

Though women are mainly concerned, urinary incontinence also affects men. The main risk factors are age, pregnancy for women and antecedents of prostate surgery for men.

Urologists have different treatments for patients suffering from severe urinary incontinence. Unfortunately, in most cases, these solutions are only partially effective and the rate of surgical reinterventions due to complications caused by these treatments is still high.
