Methods: Seventeen women (age: 35.5 ± 3.5, BMI: 21.1 ± 3.2) were studied at about 6 weeks, 3 months, and 6 months after vaginal delivery. Urinary incontinence was assessed by the International Consultation on Incontinence Questionnaire-Short Form. Pelvic floor function was assessed by the anteroposterior diameter of the levator hiatus using transperineal ultrasound. Women who delivered for the first time at 35 years and/or older were defined as being of advanced maternal age. Results: Nine of 17 women (52.9%) were of advanced maternal age and 5 experienced postpartum stress urinary incontinence. Four of these 5 women (80.0%) were of advanced maternal age. The anteroposterior diameter of the levator hiatus at rest was significantly greater in the advanced maternal age women than in the younger maternal age women at 3 and 6 months postpartum (p < 0.01). Among the continent women, the anteroposterior diameter of the levator hiatus at rest was significantly greater in the advanced maternal age women than in the younger maternal age women at 6 months postpartum (p = 0.004). However, among the advanced maternal age women, all parameters of the anteroposterior diameter of the levator hiatus were not significantly different between the women with and without stress urinary continence. Conclusion: Recovery of pelvic floor function following delivery may be delayed in women of advanced maternal age at first delivery because of the damage to the pelvic floor during pregnancy and vaginal delivery, resulting in increase in the incidence of stress urinary incontinence.展开更多

Methods: Patients with stress urinary incontinence who received surgical treatment in Xuzhou Central Hospital between February 2015 and April 2017 were selected as the SUI group of the research, female healthy volunteers who received physical examination during the same period were selected as the control group A of the research, and patients who received total hysterectomy for benign disease during the same period were selected as the control group B of the research. The ultrasound parameters of pelvic floor characteristics of SUI group and control group A were determined before surgery, and the contents of collagen metabolism indexes, extracellular matrix metabolism indexes and apoptosis genes of SUI group and control group B were determined after surgery. Results:Pelvic floor ultrasound parameters BND, R-RVA, V-RVA and UR levels of SUI group were higher than those of control group A;Col-I and Col-II contents as well as Fibulin-5, LOX and LOXL1 mRNA expression in pelvic floor tissue of SUI group were significantly lower than those of control group B and negatively correlated with pelvic ultrasound parameter BND while ICTP content as well as Calpain1, Calpain2, Caspase-3, LC3-II and Beclin-1 mRNA expression was significantly higher than those of control group B and positively correlated with pelvic floor ultrasound parameter BND. Conclusion: The patients with stress urinary incontinence have the ultrasonic characteristics of weak pelvic support and enhanced urethral activity, and the abnormal collagen metabolism and excessive apoptosis are closely related to the changes of pelvic floor.展开更多
