Introduction: Vaginal vault prolapsus is a challenging problem for the patients and physicians. There may be differences between young and elderly patients in terms of efficiency and safety of surgical procedures. Aim: The aim of our study was to compare the efficiency of the Posterior Intravaginal Sling (PIVS) procedure in older versus younger patient groups. Materials and Methods: A total of 40 patients who underwent the PIVS procedure were chosen. Twenty of these patients were younger than 60 years of age (Group I) while the other 20 patients were 60 years of age or older (Group II). Preoperative Pelvic Organ Prolapsed Quantification (POP-Q) reference points were compared with postoperative data at the first year following surgery. Student’s t-test was used to analyse continuous variables and the χ2 test was used to analyse categorical data. The Mann–Whitney test was used for data that were not normally distributed. Results: Anatomical cure rates were 90 percent in both groups (p=1.00). There were significantly greater improvements in POP-Q points in group I than group II. Conclusion: It could be concluded that PIVS as minimally invasive procedure for vaginal vault prolapsed and is effective in all age groups.
