The Follow-up of Mesh/Native Tissue Complications Study(Part I)

A Multi-center Study: The Follow-up of Complications for Women Having Pelvic Reconstruction Surgery With Mesh/Native Tissue(Part I)

This study aims to investigate the incidence and distribution of complications after different pelvic reconstruction surgeries using mesh/native tissue in multi-centers using the IUGA/ICS complication classification system(the Category-Time-Site(CTS) coding).

Patients who undergo different pelvic floor reconstructive surgeries for the cure of pelvic organ prolapse(POP)and/or stress urinary incontinence(SUI) between June 2018 and June 2023 from 27 tertiary hospitals are prospectively collected.Our study aims to follow-up and report the incidences of postoperative complications according to the International Urogynecological Association-International Continence Society(IUGA-ICS) Complication Classification Coding(Category-Time-Site coding system).The aimed pelvic floor reconstructive surgeries involve anterior,apical, posterior or total pelvic reconstruction with trans-vaginal mesh,open/laparoscopic sacrocolpopexy(Y-tape/self-cut synthesized mesh),repair using native tissue(sacrospinous ligament fixation, high uterosacral ligament suspension,ischial spinous fascia fixation, the Lefort operation and so on)and as well as anti-urinary incontinence surgeries(tension-free vaginal tape).

Our follow-up process start after patients have completed the operation,thus our study do not affect patients' choice of surgical method.

Inclusion Criteria:

- 1. Patients who undergo pelvic floor reconstructive surgeries for pelvic organ prolapse and/or stress urinary incontinence. The aimed pelvic floor reconstructive surgeries involve anterior, apical, posterior or total pelvic reconstruction with trans-vaginal mesh, open/laparoscopic sacrocolpopexy (Y-shape tape/self-cut synthesized mesh), repair using native tissue(sacrospinous ligament fixation, high uterosacral ligament suspension, ischial spinous fascia fixation, the Lefort operation and so on) and as well as anti-urinary incontinence surgeries(tension-free vaginal tape). The indications are respectively as follows:

1. Total pelvic reconstruction with trans-vaginal mesh Indications: 1) Patients experienced recurrence of prolapse in the same compartment that has a history of pelvic floor repair surgery; 2) The choice for elder patients who will accept primary surgery for advanced POP (staging III or IV).
2. Open/Laparoscopic sacrocolpopexy (Y-shape tape/self-cut synthesized mesh) Indications: 1) Presenting with at least 3 prolapse of the uterus, with or without concomitant cystocele and rectocele; 2) Symptomatic stage 2 or greater prolapse of the vaginal vault or apical recurrence.
3. Repair using native tissue(sacrospinous ligament fixation, high uterosacral ligament suspension, ischial spinous fascia fixation, Lefort) Indications:1)Presenting symptomatic stage 2 or greater prolapse of the uterus, with or without concomitant cystocele and rectocele. The procedure(sacrospinous ligament fixation, high uterosacral ligament suspension, ischial spinous fascia fixation) usually is performed after hysterectomy or when the uterus is preserved. 2)If postmenopausal women present with advanced uterus or vaginal apex prolapse, and have no desire of sexual life, the Lefort operation would be performed.
4. Anti-urinary incontinence surgeries: tension-free vaginal tape. Indications: Stress urinary incontinence(SUI) patients who have 1）hyperactivity of urethra, or 2）internal urethral sphincter disorder; Or 3）mainly presenting SUI symptoms in patients with mixed urinary incontinence.

2. The failure or recurrence of prolapse the same compartment that has been underwent repair using native tissue.

Exclusion Criteria:

• (1) the recurrence occurred on the same pelvic compartment with a prior history of prolapse repair surgery using mesh, an implant or a graft; (2) a prior history of anti-incontinence surgery using tape; however, patients who are inferred to accept procedures for POP this time are not included; (3) acute/chronic pelvic inflammation, genital tract infections；(4) any severe medical diseases that precluded the operations.
