This work aimed to study the application of pelvic floor dynamic images of magnetic resonance imaging (MRI) based on the particle swarm optimization (PSO) algorithm in female stress urinary incontinence (SUI). 20 SUI female patients were selected as experimental group, and another 20 healthy females were taken as controls. PSO algorithm, K-nearest neighbor (KNN) algorithm, and back propagation neural network (BPNN) algorithm were adopted to construct the evaluation models for comparative analysis, which were then applied to 40 cases of female pelvic floor dynamic MRI images. It was found that the model proposed had relatively high prediction accuracy in both the training set (87.67%) and the test set (88.46%). In contrast to the control group, there were considerable differences in abnormal urethral displacement, urethral length changes, bladder prolapse, and uterine prolapse in experimental patients ( P < 0.05 ). After surgery, the change of urethral inclination angle was evidently reduced ( P < 0.05 ). To sum up, MRI images can be adopted to assess the occurrence of female SUI with abnormal urethral displacement, shortening of urethra length, bladder prolapse, and uterine prolapse. After surgery, the abnormal urethral movement was slightly improved, but there was no obvious impact on bladder prolapse and uterine prolapse.

CONTEXT AND OBJECTIVE: Urinary incontinence is a public health problem that affects more than 200 million people worldwide. Stress incontinence is the most prevalent type. Pelvic floor muscle exercises have been used for treating it, although there is no consensus regarding their application. The aim of this study was to compare the results from treating female stress urinary incontinence with pelvic floor muscle exercises with or without physiotherapist supervision. DESIGN AND SETTING: This was a randomized, prospective, controlled trial in the Urogynecology and Vaginal Surgery Sector, Universidade Federal de São Paulo. METHODS: Forty-four women were randomized to be treated for stress urinary incontinence with pelvic floor exercises for three consecutive months, into two groups: one with and the other without physiotherapist supervision. They were evaluated before and after treatment using a quality-of-life questionnaire, pad test, micturition diary and subjective evaluation. Descriptive analysis was used to evaluate the population. The homogeneity of the two groups was evaluated using the Kruskal-Wallis and Chi-squared tests. The success of the two groups after treatment was evaluated using the Wilcoxon test. RESULTS: The supervised group showed statistically greater improvement in the pad test, micturition diary and quality of life than did the control group. In the subjective evaluation, only 23.8% of the control group patients were satised with their treatment. In the supervised group, 66.8% of patients did not want any other treatment. CONCLUSION: Supervised pelvic floor muscle exercises presented better results in objective and subjective evaluations than did unsupervised exercises.

Introduction: Pelvic floor muscle training (PFMT) and electrical stimulation (ES) are conservative models of therapy for treating female stress urinary incontinence (SUI). The presence of estradiol receptors in the lower urinary tract advances the case for estradiol therapy in SUI. The aim of our study was to investigate the effects of the combination of pelvic floor rehabilitation and intravaginal estriol (IE) on SUI treatment in postmenopausal women. Material and Methods: Sixty-two women with SUI were randomized to PFMT, ES and biofeedback (Group 1) or the same treatment plus 1 mg IE (Group 2) for 6 months. Patients were evaluated with medical history, pelvic examination, urodynamics, 24-hour pad test. Urinary incontinence was evaluated using the International Consultation on Incontinence questionnaire on urinary incontinence short form and quality of life using the Incontinence Impact Questionnaire-Short Form. Results: Two patients were lost at follow-up and one discontinued the study. Mean urine leakage at the 24-hour pad test dropped from 42.3 ± 20.2 g/die to 31.5 ± 14.2 g/die in Group 1 and from 48.3 ± 19.8 g/die to 22.3 ± 10.1 g/die in Group 2. Symptoms scores and incontinence status were statistically significant better in Group 2 when compared to Group 1. Conclusion: IE added to PFMT, ES and BF is a safe and efficacious first-line therapy in postmenopausal women with SUI.
