Gynecological follow-up
Data on the duration of menstruation and the TRM before and after surgery are summarized in Table S3. A total of 231 patients and 191 patients were examined at 3- and 6-months after surgery. For group B patients, the mean durations of menstruation at 3- and 6-months follow-up were significantly shorter than those before surgery (8.1 ± 2.5 days and 8.3 ± 2.4 days, respectively, p < 0.05). For group A patients, the mean durations of menstruation at 3- and 6-months follow-up were significantly shorter than those before surgery (p < 0.05). The TRM at the median-month follow-up was significantly strengthen in both groups (p < 0.05)
Data on the durations of menstruation at 3- and 6-months follow-up are summarized in Table S4. At 3- and 6-months follow-up, the mean durations of menstruation were 8.1 ± 2.3 days and 8.1 ± 1.6 days, respectively, and no significant difference was observed between the two groups (p > 0.05). Subsequently, we considered 7 days as the mean duration of menstruation and divided the patients into two subgroups. We found that 55.3% (126/228) of patients in group B had an optimal duration of menstruation (i.e., 7 days) at 3- and 6-months follow-up compared to 38.0% (19/50) of patients in group A (p< 0.05). At 3- and 6-months follow-up, 183 group-A patients and 138 group B patients underwent MRI. No significant difference was observed in the CSD length, width, and depth, and the TRM of the CSD was thinner after vaginal repair (p > 0.05). Class-A healing was defined as a duration of menstruation of no more than 7 days and a TRM of no less than 5.8 mm after vaginal repair17. Class-A healing was more prevalent in group-B patients compared to group-A patients (44.7% vs 30.0%; p< 0.05).
