OBJECTIVE
Mesh implants are widely used in surgery for female pelvic organ prolapse. Mesh shrinkage is thought to be common and caused by immunological processes. In this longitudinal study, we examined mesh dimensions at 2 time points after implantation.
STUDY DESIGN
We analyzed translabial 4-dimensional ultrasound (US) volume datasets of women seen 3-52 months after anterior compartment mesh. Datasets of first and last postoperative appointments were analyzed, with the operator blinded against all other data.
RESULTS
Forty women were assessed at least twice, comprising 59.6 woman-years. Thirty-seven of 40 (93%) were satisfied at their last appointment. Eighteen of 40 considered themselves cured, and 18 of 40 felt improved. Objective recurrence (cystocele stage 2 or greater) was seen in 16 of 40. Midsagittal mesh length increased significantly (35.8 vs 32.7; P = .006), and coronal mesh diameters increased nonsignificantly (37.4 vs 36.6 mm; P = .44).
CONCLUSION
Over an observation period of almost 60 woman-years, we found no evidence of mesh contraction.
目的
网片在女性盆腔器官脱垂的外科手术中被广泛应用。人们认为网片收缩很常见，其原因是免疫过程。在这项纵向研究中，我们在植入后两个时间点检查了网片的尺寸。
研究设计
我们分析了经阴道 4 维超声（US）容积数据集，这些女性在接受前房网片后 3-52 个月接受了检查。分析了首次和最后一次手术后的数据集，操作员对所有其他数据均不知情。
结果
40 名女性至少接受了两次评估，共 59.6 名女性年。40 名女性中有 37 名（93%）在最后一次就诊时表示满意。18 名女性认为自己痊愈了，18 名女性认为自己有所改善。40 名女性中有 16 名出现了客观的复发（膀胱膨出 2 度或更严重）。中矢状面网片长度显著增加（35.8 比 32.7；P =.006），冠状面网片直径增加不显著（37.4 比 36.6 毫米；P =.44）。
结论
在近 60 名女性年的观察期内，我们没有发现网片收缩的证据。
