Urinary incontinence is defined as the involuntary loss of urine, which is both a social and hygienic problem that can be objectively demonstrated. It occurs when the internal sphincter and urethral closure pressure are unable to withstand increases in intra-abdominal pressure due to reductions in the differences between intraurethral and intravesical pressures.
