Success is similar for TV mesh and native tissue repair
Kahn B, Varner RE, Murphy M, et al. Transvaginal mesh compared with native tissue repair for pelvic organ prolapse. Obstet Gynecol. 2022;139:975-985. doi:10.1097/AOG.0000000000004794.
The distribution of vaginal mesh kits for the repair of POP was halted by the US Food and Drug Administration (FDA) in 2019. However, concerns have been raised about the measures used by the FDA to justify pulling these devices from the market. A cohort study compared 36-month outcomes between women who underwent prolapse repair with newer generation transvaginal mesh versus native tissue repair.
In a nonrandomized prospective multicenter cohort study, Kahn and colleagues compared outcomes in women with POP who underwent native tissue repair or transvaginal mesh repair with the Uphold LITE vaginal support system. The study’s objective was to compare the safety and efficacy of native tissue and transvaginal mesh prolapse repairs at 36 months postoperatively.
Treatment success was measured based on composite and individual measures of anatomic and subjective success, need for retreatment, and the occurrence of adverse events. Quality of life (QoL) measures also were obtained using validated questionnaires. Intention-to-treat and per-protocol analyses were performed.
Composite success rate was higher for mesh repair
A total of 710 patients were screened for eligibility (225 received transvaginal mesh and 485 received native tissue repair). Transvaginal mesh placement was found to be significantly superior to native tissue repair for composite success (84% vs 73%, P = .009) when prolapse within the hymen (that is, Ba and/or C < 0 on the Pelvic Organ Prolapse Quantification System) was used to define anatomic success.
Adverse events were similar between transvaginal mesh and native tissue repair groups, with most adverse events occurring within the first 6 months. The mesh exposure rate was 4.9%. Of the 13 incidents of mesh exposure, 4 patients required surgical intervention and 1 incident was considered a serious adverse event. QoL measures demonstrated improvement without any statistically significant differences between the treatment cohorts. ●
This study established the superiority and safety of newer generation transvaginal mesh used for the treatment of pelvic organ prolapse. Women who received newer generation transvaginal mesh can be reassured that the prolapse recurrence rates are low and that adverse events related to their mesh are rare—even when compared with those of native tissue repair. Patients also may be reassured that most adverse events would have occurred within 6 months of the initial prolapse repair surgery
