| Stages are based on the maximal extent of prolapse relative to the hymen: |
| Stage 0: |
No prolapse; anterior and posterior points are all – 3 cm. |
| Stage I: |
The criteria for stage 0 are not met, and the most distal prolapse is more than 1 cm above the level of the hymen |
| Stage II: |
The most distal prolapse is between 1 cm above and 1 cm below the hymen |
| Stage III: |
The most distal prolapse is more than 1cm below the hymen but no further than 2 cm less than TVL |
| Stage IV: |
Represents complete vault eversion |
 |
| Six vaginal sites used in staging prolapse: |
| Points Aa and Ba anteriorly |
| Points Ap and Bp posteriorly |
| Point C for the cervix or vaginal apex |
| Point D for the posterior fornix (not measured after hysterectomy) |
| GH – genital hiatus |
| PB – perineal body |
| TVL – total vaginal length |
