目的:为了确定年龄,高度,体重和体重指数与尿壶间隙测量相关,以及这些因素是否混淆了LUG与POP症状和体征之间的关系。
方法:对2020年1月至2021年12月在三级泌尿妇科病房就诊的女性进行回顾性研究。保存的超声体积数据的后处理用于测量左尿道-尿道间隙。对所有其他数据视而不见。测试了该测量与器官下降和食管面积的关联,和高度,研究了体重和体重指数是否存在任何潜在的混杂效应.
结果:纳入期间的624名女性主要表现为压力性尿失禁(448,72%),尿失禁(469,75%)和/或脱垂(338,54%)。评估时的平均年龄为58岁(范围,20-94)年,平均身高为163(范围,142-182)cm,平均体重80(41-153)公斤,平均BMI为30(17-65)kg/m2。可以在613名女性中获得LUG测量结果,导致12*613=7356测量。个别女性的平均LUG右侧为2.35厘米,左侧为2.32厘米(n.s.),总体平均2.34厘米(SD0.63)。平均LUG与脱垂的症状和体征有关,在POPQ和成像上,但与身高无关(P=0.36),体重(P=0.2)或BMI(P=0.09)。
结论:左尿道间隙测量似乎与身高无关,我们人口的体重或BMI,消除了LUG个性化的需要。然而,这并不排除这种生物识别措施的种族间差异。本文受版权保护。保留所有权利。
OBJECTIVE: To determine whether height, weight and body mass index (BMI) are associated with the levator-urethra gap (LUG) measurement, and whether these factors confound the relationship between LUG and symptoms and signs of pelvic organ prolapse (POP).
METHODS: This was a retrospective study of women seen at a tertiary urogynecology unit between January 2020 and December 2021. Postprocessing of saved ultrasound volume data was used to measure the LUG, blinded against all other data. This measurement was tested for its association with organ descent and hiatal area, and height, weight and BMI were investigated for any potential confounding effect.
RESULTS: The 624 women seen during the inclusion period presented mostly with stress urinary incontinence (448/624 (72%)), urgency urinary incontinence (469/624 (75%)) and/or prolapse (338/624 (54%)). Mean age at assessment was 58 (range, 20-94) years, mean height was 163 (range, 142-182) cm, mean weight was 80 (range, 41-153) kg and mean BMI was 30 (range, 17-65) kg/m2. LUG measurements could be obtained in 613 women, resulting in 7356 (12 × 613) measurements. The average LUG in individual women measured 2.35 cm on the right and 2.32 cm on the left side (difference not significant), with a mean ± SD of 2.34 ± 0.63 cm overall. Mean LUG was associated with symptoms and signs of prolapse, both on clinical examination (POP quantification system) and on imaging, but not with height (P = 0.36), weight (P = 0.20) or BMI (P = 0.09).
CONCLUSIONS: Levator-urethra gap measurements do not seem to be significantly associated with height, weight or BMI in our population, obviating the need for individualization of LUG. However, this does not exclude interethnic variability of this biometric measure. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.
