Lower urinary tract symptoms (LUTS), in particular urinary incontinence (UI), commonly develops during pregnancy or following delivery. This study was conducted to investigate the prevalence of the LUTS before and during pregnancy, and to demonstrate the relationships between various obstetric parameters and UI.
For this observational study, 1,501 consecutive primiparae who delivered at ≥ 36 gestational weeks were recruited in a tertiary hospital. A urogynecological questionnaire was used to assess the prevalence of LUTS before and during pregnancy. The relationships between various obstetric parameters and UI were analyzed.
Prevalence of LUTS increased over the course of pregnancy. The most commonly reported LUTS symptoms, regardless of pregnancy trimester, were nocturia (51.1%) and frequency (40.3%), UI (37.5%), urgency (31.1%), incomplete bladder emptying (26.3%), straining (15.3%), and voiding difficulty (14.5%). Stress UI (SUI) (26.7%) was more common during pregnancy than mixed UI (6.1%) or urge UI (4.7%). Women with a prepregnancy BMI >30 were at increased risk of developing de novo SUI during pregnancy. Urge incontinence during pregnancy was associated with smoking.
The prevalence of LUTS generally increased with gestational age. UI during pregnancy was associated with prepregnancy BMI and smoking.
下尿路症状（LUTS），特别是尿失禁（UI），在妊娠期间或分娩后常发生。本研究旨在调查妊娠前和妊娠期间 LUTS 的患病率，并探讨各种产科参数与 UI 之间的关系。
本观察性研究纳入了在一家三级医院分娩且孕周≥36 周的 1501 例初产妇。使用尿失禁问卷调查评估妊娠前和妊娠期间 LUTS 的患病率。分析了各种产科参数与 UI 之间的关系。
LUTS 的患病率随着妊娠的进行而增加。无论妊娠三期中，最常见的 LUTS 症状是夜尿（51.1%）和尿频（40.3%）、UI（37.5%）、尿急（31.1%）、膀胱不完全排空（26.3%）、费力（15.3%）和排尿困难（14.5%）。与混合性 UI（6.1%）或急迫性 UI（4.7%）相比，妊娠期间压力性 UI（SUI）（26.7%）更为常见。孕前 BMI＞30 的女性在妊娠期间发生新发 SUI 的风险增加。妊娠期间急迫性尿失禁与吸烟有关。
LUTS 的患病率通常随妊娠周数增加而增加。妊娠期间的 UI 与孕前 BMI 和吸烟有关。
