Possible cause of failure after McCall culdoplasty

Objective: To evaluate prospectively the rate of postoperative failure of McCall culdoplasty and the presence of a history of vaginal delivery of macrosomic infants as risk factors in patients with stage III or symptomatic stage II apical prolapse without any other pelvic floor defects. Materials and methods: Patients with pelvic organ prolapse who underwent vaginal hysterectomy and McCall culdoplasty procedures were staged according to the POP-Q system before and after the operation (n = 70). POP-Q stages, age, gravidity, parity, body mass index (BMI), and the presence of diabetes mellitus in patients with or without history of vaginal delivery of macrosomic infants were analyzed. A birth weight of ≥4,000 g was accepted as macrosomia. Operative failure was defined as a postoperative POP-Q stage ≥ stage III of the apical segment. Follow-up period was 26.5 ± 6.37 months. Results: Twenty-seven women had a history of macrosomic delivery and the remaining 43 did not. Postoperative failure was observed in 15 patients (44.4%) in the macrosomia group and in 3 patients (6.9%) in the control group. Postoperative failure was seen more frequently in the macrosomia group (Pearson's chi-square test, P = 0.000). No significant difference was found between the groups regarding age, gravidity, parity, BMI and the presence of diabetes mellitus. Conclusion: Failure of McCall culdoplasty occurs more frequently in patients with history of vaginal delivery of macrosomic infants, possibly due to direct pelvic floor damage. This technique should not be used in patients with a possible history of direct pelvic floor damage.
