RESUMO
Objective:To observe the clinical effect of pelvic floor ultrasound in the diagnosis and rehabilitation training of postpartum stress urinary incontinence(SUI).Methods:From May 2017 to May 2019, 200 SUI patients and 200 healthy pregnant women in the same period admitted to the First People's Hospital of Huzhou were selected in this study.All the subjects were tested by perineum and pelvic floor ultrasound, and the patients with SUI were instructed to carry out pelvic floor muscle rehabilitation training, the level of rehabilitation training effect was evaluated, and to statistically analyze the difference of pelvic floor ultrasound parameters between the patients with SUI and the healthy women, and the patients with different levels of efficacy.Results:The results of pelvic floor ultrasound in SUI patients were significantly higher than those in healthy women( t=6.536-14.925, all P<0.05). The rate of urinary leakage in SUI patients [88.50%(177/200)] was significantly higher than that in healthy women [10.50%(21/200)](χ 2=243.384, P<0.05). The total effective rate of rehabilitation training was 79.50%(159/200). The bladder neck moving distance, urethra rotation angle, posterior angle of bladder urethra in resting state and posterior angle of bladder urethra in Valsalva state in SUI patients with ineffective rehabilitation training were significantly higher than those in SUI patients with general effective rehabilitation training( t=4.662-12.537, all P<0.05). The formation rate of urethra infundibulum in SUI patients with ineffective rehabilitation training [70.73%(29/41)] was significantly higher than that in SUI patients with effective rehabilitation training [19.50%(31/159)](χ 2=40.744, P<0.05). Conclusion:The rehabilitation training of discoid muscles can effectively relieve the related clinical symptoms of postnatal SUI patients.The detection of pelvic ultrasound has a certain clinical value in the diagnosis of postpartum SUI and evaluation of rehabilitation training effect.
RESUMO
Objective To explore the value of contrast-enhanced ultrasound (CEUS) and intraluminal contrast in the differential diagnosis of postmenopausal endometrial benign and malignant lesions.Methods The ultrasound data of 90 patients with postmenopausal endometrial lesions diagnosed in our hospital between March 2016 and March 2018 were retrospectively analyzed.According to pathological findings,they were divided into benign group (55 cases) and malignant group (35 cases).The endometrial thickness of endovascular contrast,rise time (RT),time to peak (TTP),base intensity (BI),and peak intensity (PI) of CEUS in two groups were compared.Receiver operating characteristic curves (ROC) were used to compare the efficacy of different ultrasound parameters in benign and malignant endometrial by using pathology diagnosis as "gold standard".Results The endometrial thickness and PI were significantly higher in the malignant group than those in the benign group (P ＜ 0.05),while the RT and TTP were significantly lower than benign group (P ＜ 0.05),with no statistical difference in BI (P ＞ 0.05).The ROC curve showed that PI has the highest area under curve (AUC) in the differential diagnosis of benign and malignant endometrial lesions (AUC =0.983),followed by RT and TTP (AUC =0.889,0.872),and intimal thickness (AUC =0.766).AUC of PI was significantly higher than RT,TTP and intimal thickness (P ＜ 0.05),and the best cut-off point for PI ≥20.23 dB.The sensitivity of PI,RT,and TTP in differentiating benign and malignant endometrial lesions was significantly higher than that in intimal thickness (P ＜ 0.05),whereas the specificity and positive likelihood ratio (+ LR) of PI were significantly higher than those of RT,TTP,and intimal thickness (P ＜ 0.05).Conclusions Compared with intracavitary ultrasound,CEUS has better diagnostic value in differentiating benign and malignant endometrial tumors.Among them,the diagnostic sensitivity and specificity of PI≥20.23 dB are higher.
