To determine reference values for postvoid residual (PVR) volume for patients referred to a tertiary urogynecology center.
After Institutional Review Board approval, we performed a retrospective chart review of all new patients presenting to our referral center. We assessed associations between PVR and patient demographics, pelvic floor symptoms, and physical examination by Wilcoxon rank sum or Kruskal-Wallis tests as appropriate. A multivariable logistic regression model was used to calculate odds ratios for patient characteristics associated with PVR in the top age range-specific decile.
Three hundred sixty-one patients were included in the analysis. The median PVR was 20 mL (interquartile range, 1st, 3rd quartiles, 10, 50). Older age was associated with higher PVR (P < 0.001). The median PVR in participants younger than 40 years was 10 mL, ages 40 to 49 years was 18 mL, 50 to 69 years was 20 mL, 70 to 79 years was 38 mL and in women older than 79 years was 50 mL. A multivariable analysis showed that prolapse stage (odds ratio [OR], 3.46 with prolapse stage 2-4 vs stage 0-1; P = 0.001), history of stroke (OR, 7.62; [95% CI 2.17-26.77, P = 0.002]), narcotic use (OR, 2.45; [95% CI 1.01-5.92; P = 0.047]), and urinary frequency (OR, 2.61; [95% CI, 1.14-5.98; P = 0.024]) were risk factors for increased PVR (as defined at >90%ile for age), independent of the age-related elevation.
The majority of patients presenting for urogynecologic evaluation had a low PVR with a median of 20 mL. Postvoid residual was higher for older age groups but nearly all volumes were less than 100 mL. The utility of a PVR measurement is highest for patients with pelvic organ prolapse, urinary frequency, narcotic use, or history of stroke.
确定转诊至三级泌尿妇科中心的患者的膀胱残余尿量（PVR）参考值。
在获得机构审查委员会批准后，我们对所有新转诊至我们中心的患者进行了回顾性图表审查。我们通过 Wilcoxon 秩和检验或 Kruskal-Wallis 检验评估了 PVR 与患者人口统计学、盆底症状和体格检查之间的关联。使用多变量逻辑回归模型计算了与 PVR 最高年龄特定十分位数相关的患者特征的优势比。
共纳入 361 名患者进行分析。PVR 的中位数为 20 mL（四分位距，1 分位、3 分位，10、50）。年龄较大与较高的 PVR 相关（P<0.001）。年龄小于 40 岁的参与者的 PVR 中位数为 10 mL，年龄在 40 至 49 岁之间为 18 mL，50 至 69 岁为 20 mL，70 至 79 岁为 38 mL，年龄大于 79 岁为 50 mL。多变量分析显示，脱垂分期（优势比[OR]，2-4 期与 0-1 期相比为 3.46；P=0.001）、中风史（OR，7.62；[95%CI，2.17-26.77，P=0.002]）、使用麻醉药物（OR，2.45；[95%CI，1.01-5.92；P=0.047]）和尿频率（OR，2.61；[95%CI，1.14-5.98；P=0.024]）是 PVR 升高的危险因素（定义为>90%年龄特异性 PVR），独立于年龄相关的升高。
大多数就诊于泌尿妇科的患者的 PVR 较低，中位数为 20 mL。年龄较大的患者 PVR 更高，但几乎所有的 PVR 均小于 100 mL。对于有盆腔器官脱垂、尿频率、使用麻醉药物或中风史的患者，PVR 测量的作用最大。
