Uterine prolapse is diagnosed in stages, with each stage describing how far the uterus has descended. In many cases, other pelvic organs – such as the bladder or bowel – are also prolapsed into the vagina.

The four stages of uterine prolapse are:

• Stage I: the uterus is in the upper half of the vagina
• Stage II: the uterus is near or at the opening of the vagina
• Stage III: the uterus protrudes out of the vagina
• Stage IV: the uterus is completely out of the vagina
