There are many causes of urinary incontinence. For example, the most common type, stress urinary incontinence, is related to the relaxation of the pelvic floor muscles and the bladder's detrusor muscle. Conditions like pelvic organ prolapse, as well as factors like being a mature mother or excessive obesity, can lead to stress urinary incontinence. Urgency urinary incontinence is often caused by severe bladder inflammation or associated with certain chronic diseases, such as diabetes or bladder neck sclerosis. Overflow incontinence, most commonly seen in elderly males, typically results from prostate enlargement that blocks the urethra, leading to urinary retention and consequently overflow incontinence. Therefore, to understand the specific causes of urinary incontinence, it is crucial first to differentiate the types of incontinence and combine this with the patient’s specific situation and related examinations for a clear diagnosis.
