Design outcomes

Primary

MeasureTime frame
1. Surgical success (= anatomic cure, subjective improvement and no re-treatment necessary) in the treatment of apical prolapse compared to unilateral SSLF at 12 months; 2. Improvement of quality of life related to pelvic floor function at 12 months after surgery (PFDI-20). Secondary objectives

Secondary

MeasureTime frame
1. Morbidity (Pain, ADL, hospital stay, surgical parameters, postoperative recovery, blood loss); 2. Quality of life score (PFDI-20): improvement stratified by compartment; 3. Sexual satisfaction (PISQ-12) improvement from baseline 4. To asses superiority of BSC mesh in surgical success (anatomic cure, subjective improvement and no re-treatment necessary) in the treatment of apical prolapse compared to unilateral SSLF at 12 months when non-inferiority has been proven; 5. Procedure related serious adverse events.
