**4.1 Pelvic floor prolapse**

Gynecology differentiates between descensus of the anterior (cystocele), central (uterine prolapse or vaginal stump descensus) and posterior (rectocele, enterocele) compartment, often affecting several compartments at the same time. In addition, a classification according to the level of the defect according to DeLancey takes place:


The classification of prolapse is based on the height of the hymenal hem (ICS/IUGAclassification). For example, a rectocele is classified according to the descent of the posterior vaginal wall. If this remains above the hymenal hem during pushing, a stage 1 is present (>1 cm proximal of the hymenal hem). If it descends to the hymenal hem, stage 2 (± 1 cm proximal or distal the hymenal hem), and below that, stage 3(>1 cm distal of the hymenal hem). Stage 4 describes a total prolapse of the uterus and/or the vagina. The same applies to cystocele or descensus uteri [8].
