STUDY OBJECTIVE: To compare obstetric histories of women who had surgical correction of urinary incontinence or pelvic organ prolapse with a similar group who did not.
DESIGN: Case control study (Canadian Task Force classification II-2).
SETTING: Urban, community-based, private practice teaching hospital.
PATIENTS: Four hundred eighty women (age 51.4 +/- 13.0 yrs) who underwent corrective surgery for urinary incontinence, pelvic organ prolapse, or both, and whose obstetric history was obtainable through chart review. The control group was composed of 150 women (age 50.7 +/- 9.6 yrs) having routine screening mammography who completed a questionnaire regarding obstetric, gynecologic, and urologic history.
MEASUREMENTS AND MAIN RESULTS: Patients and controls did not differ significantly in terms of age, race, height, weight, body mass index, or smoking history. Women who underwent surgery were of greater parity (2.5 +/- 1.2 vs 2.0 +/- 1.2, p<0.001), less often nulliparous (3% vs 18%, p<0.001), less likely to have had a cesarean delivery (4% vs 15%, p<0.001), and more likely to have had a vaginal delivery (94% vs 77%, p<0.001) than those with no surgery. The odds ratio of patients who had a vaginal delivery compared with controls was 4.7 (2.3-8.3), and that for cesarean delivery was 0.22 (0.11-0.43). Analysis of specific delivery information found that, compared with controls, patients were older by 4 years at time of their first delivery (28.9 +/- 4.9 vs 24.9 +/- 4.9 yrs, p<0.001) and more commonly received epidural analgesia intrapartum (87% vs 40%, p = 0.004). Comparisons within the patient group, categorized by indication for surgery, revealed that women who had surgery for either prolapse alone or for both prolapse and incontinence were most likely to have had vaginal deliveries (85% incontinence alone vs 94% prolapse alone vs 97% both, p<0.001).
CONCLUSION: Increased parity, vaginal childbirth, maternal age at time of delivery, and use of epidural analgesia are associated with need for operative correction of pelvic organ prolapse or adult urinary incontinence. Conversely, cesarean delivery is associated with less need for surgical correction of incontinence or pelvic organ prolapse.
