Role of Preoperative and Postoperative Pelvic Floor Distress Inventory-20 in Evaluation of Posthysterectomy Vault Prolapse.

BACKGROUND

Posthysterectomy vault prolapse is a common problem after vaginal or abdominal hysterectomy. The objective was to assess the role of Pelvic Floor Distress Inventory 20 (PFDI-20) in evaluation of vault prolapse.

MATERIALS AND

METHODS

Prospective study in 20 women with posthysterectomy vault prolapse of Stage 2 and above. The outcome measure was to calculate PFDI-20 score in all cases before surgical intervention and to recalculate it again in 6 months after different surgical procedures for vault prolapse and to statistically compare the PFDI-20 score in different types of surgery over 4 years period at a tertiary referral hospital for surgical treatment. Prolapse was classified using Pelvic Organ Prolapse Quantification and intraoperative findings. All women were operated for vault prolapse as per hospital protocol and stage of prolapse by either vaginal sacrospinous fixation or abdominal sacrocolpopexy.

RESULTS

Mean age, parity, and body mass index were 54.8 years, 3.5, and 22.71 kg/m2 respectively. Preceding surgery was vaginal hysterectomy in 75% women and abdominal hysterectomy in 25% women. Complaints were bulge or mass feeling at perineum (100%), pressure in lower abdomen and perineum (55%), and constipation (60%). The type of prolapse was vault prolapse (100%), cystocele (100%), rectocele (100%), and enterocele (45%). The range of PFDI-20 was 88-152 with mean being 123.50 ± 22.71 before surgery while its range decreased significantly to 80-126 with mean being 106.40 ± 16.45 after surgery (P < 0.01). Mean postoperative PFDI-20 score was 107.40 in vaginal sacrospinous fixation group and was 105.30 in abdominal sacrocolpopexy group and was not statistically different (P = 0.18).

CONCLUSION

PFDI-20 score can be used to see the adverse impact of vault prolapse on pelvic floor and to assess the beneficial effect of different types of surgeries on the score.
