The aim of this study was to assess pelvic floor muscle (PFM) strength and perception and its correlation with stress urinary incontinence (SUI). One hundred and one women were divided into two groups according to the presence (G1=51 patients) or absence (G2=50 patients) of SUI. Subjective [urine stream interruption test (UST), visual survey of perineal contraction and transvaginal digital palpation to assess pelvic muscle contraction] and objective evaluations of pelvic floor muscles in all patients were performed (vaginal manometry). During the UST, 25.5% of G1 patients and 80% of G2 patients were able to interrupt the urine stream (p<0.05). Digital evaluation of pelvic muscular contraction showed higher strength in G2 than in G1 patients (p<0.0001). Perineometer evaluation of PFM strength was significantly higher in the continent group (p<0.001). Pelvic floor muscle weakness in incontinent patients demonstrates the importance of functional and objective evaluation of this group of muscles.
本研究的目的是评估盆底肌肉（PFM）力量、感知及其与压力性尿失禁（SUI）的相关性。101名女性根据是否存在SUI分为两组（G1 = 51例患者，G2 = 50例患者）。对所有患者进行了盆底肌肉的主观评估[尿流中断试验（UST）、会阴收缩视觉检查和经阴道指诊以评估盆腔肌肉收缩]和客观评估（阴道测压）。在UST期间，G1组25.5%的患者和G2组80%的患者能够中断尿流（p<0.05）。盆腔肌肉收缩的指诊评估显示G2组患者的力量高于G1组（p<0.0001）。控尿组的PFM力量经会阴压力计评估显著更高（p<0.001）。尿失禁患者的盆底肌肉无力表明对这组肌肉进行功能和客观评估的重要性。
