Genuine urinary incontinence generally occurs due to incomplete closure of the urethral sphincter, or due to insufficient urethral closure pressure. As a result, patients will show continuous leakage of urine from the urethra or involuntary urine discharge from the urethra when there is an increase in intra-abdominal pressure, such as during sneezing, coughing, or performing strenuous physical activities. Genuine urinary incontinence includes both continuous and stress urinary incontinence. Pseudo urinary incontinence is generally due to urethral stricture, commonly seen with conditions such as prostatic hyperplasia or urethral stones. The urethral stricture prevents urine from being expelled from the bladder. When the bladder becomes overly full, urine overflows through the urethra, a condition also known as overflow incontinence.
