Which pelvic floor organ can lead to urinary incontinence when it prolapses?

The uterus can lead to urinary incontinence when it prolapses because the position and support of the pelvic organs are crucial for maintaining normal urinary function. When the uterus descends from its normal anatomical position, this can put pressure on the bladder and disrupt the normal mechanisms of urinary control. This pressure can lead to various forms of urinary incontinence, particularly stress incontinence, where there is involuntary leakage of urine during physical activities that increase abdominal pressure, such as coughing or sneezing.

The relationship between the uterus and the bladder is important to consider. The uterus sits above the bladder, and when the uterus is prolapsed, it can compress the bladder, affecting its ability to store urine properly. This relationship can also influence the pelvic floor muscles and connective tissues, compounding issues related to urinary incontinence.

While other organs such as the bladder, rectum, and ovaries are relevant in the context of pelvic health, their direct involvement in urinary incontinence due to prolapse is not as significant as that of the uterus.
