To determine whether blinded and unblinded Pelvic Organ Prolapse Quantification (POP-Q) examinations differ in a randomized trial.
Blinded POP-Q examinations performed at 3 months and 1 year were compared with unblinded examinations performed by the surgeon in a randomized trial of vaginal mesh for pelvic organ prolapse.
Sixty-five patients were included in the study. Correlations between the blinded and unblinded POP-Q points and stages varied from low to moderate (rho = 0.29-0.78). At 3 months, the blinded overall prolapse recurrence rate was 45.3% compared with 39.1% based on unblinded staging (P = .34). At 1 year, the blinded overall recurrence rate was significantly higher than the unblinded recurrence rate: 68.3% vs 53.3% (P = .004). The 1-year blinded anterior wall recurrence rate was also higher than the recurrence based on unblinded staging: 56.7% vs 43.3% (P = .021).
Use of unblinded POP-Q staging resulted in underestimation of 1-year overall recurrence after prolapse repair.
在一项随机试验中，确定盲法和非盲法盆腔器官脱垂定量（POP-Q）检查是否存在差异。
在一项阴道网片治疗盆腔器官脱垂的随机试验中，对盲法 POP-Q 检查（在 3 个月和 1 年进行）与由外科医生进行的非盲法检查进行了比较。
本研究纳入了 65 例患者。盲法和非盲法 POP-Q 点和分期之间的相关性从低到中度不等（rho = 0.29-0.78）。3 个月时，盲法整体脱垂复发率为 45.3%，而非盲法分期为 39.1%（P =.34）。1 年时，盲法整体复发率明显高于非盲法复发率：68.3%比 53.3%（P =.004）。1 年时盲法前壁复发率也高于非盲法分期的复发率：56.7%比 43.3%（P =.021）。
在脱垂修复后 1 年的总体复发中，使用非盲法 POP-Q 分期会导致低估。
