Pelvic floor muscle is the main sub-system that maintains urinary continence. The weakness of pelvic floor muscles causes the stress urinary incontinence, and therefore the degree of functioning of pelvic floor muscles could be used as an index to assess the degree of stress urinary incontinence. In this study, the quantitative diagnosis algorithm was proposed to estimate the degree of stress urinary incontinence (SUI) by measuring the contraction pressure of pelvic floor muscle. For these reason, the contraction pressure measurement system from pelvic floor muscle was developed, and the measuring protocol was suggested to analysis the obtained data. As the results of clinical test, the proposed diagnosis algorithm shows the 80% of accuracy, and 20% of false positive diagnosis. On the other hand, false negative results were not confirmed. Consequentially, we thought that the proposed urinary incontinence diagnosis algorithm can quantitatively diagnose the progression of the stress urinary incontinence and it can be used for the development of the incontinence diagnosis system.

The purpose of this study was to analyze the trends and characteristics of 'stress urinary incontinence' research through word frequency analysis, and their relationships were modeled using word embedding. Abstract data of 9,868 papers containing abstracts in PubMed's MEDLINE were extracted using a Python program. Then, through frequency analysis, 10 keywords were selected according to the high frequency. The similarity of words related to keywords was analyzed by Word2Vec machine learning algorithm. The locations and distances of words were visualized using the t-SNE technique, and the groups were classified and analyzed. The number of studies related to stress urinary incontinence has increased rapidly since the 1980s. The keywords used most frequently in the abstract of the paper were 'woman', 'urethra', and 'surgery'. Through Word2Vec modeling, words such as 'female', 'urge', and 'symptom' were among the words that showed the highest relevance to the keywords in the study on stress urinary incontinence. In addition, through the t-SNE technique, keywords and related words could be classified into three groups focusing on symptoms, anatomical characteristics, and surgical interventions of stress urinary incontinence. This study is the first to examine trends in stress urinary incontinence-related studies using the keyword frequency analysis and word embedding of the abstract. The results of this study can be used as a basis for future researchers to select the subject and direction of the research field related to stress urinary incontinence.

Purpose: The effects of non-operation treatment on the stress urinary incontinence is low by 20-50%. And the way of operation has higher recovery, but it also has problems of the aftereffects and invasive aspects. So It is demanded for improvement of non-invasive to relieve this disease. Methods: The patient was 55-year-old woman who had suffered from incontinence six years ago. The patient was diagnosed by stress urinary incontinence, and treated by Herbal medicine and acupuncture treatment. The progress of symtoms was evaluated by checking the score of doing multiplication the severity and the frequency. Results: After the oriental medical treatments, the clinical score of stress urinary incontinence was improved from 12 to 0. Conclusion: This study shows that the oriental medicine may be considered for the non-invasive of stress urinary incontinence, and the study of effect is more needed.

In this study, diagnostic algorithm was suggested to diagnose quantitatively the degree of the stress urinary incontinence. The bio-signal measurement system was developed to measure the contraction pressure of the pelvic floor muscle and diagnostic parameters were drawn out by analyzing the contraction pressure data. Statistical evaluations were done to classify the diagnositc parameters by order that relationship is high. The diagnostic algorithm that was able to diagnose degree of the urinary incontinence as quantitatively was realized from the high relationship parameters.

Pelvic floor muscle is the main subsystem that maintains urinary continence. It is possible to diagnose the degree of the stress urinary incontinence(SUI) by evaluating the contraction pressure of the pelvic floor muscle. Bio-signal measurement system was developed to measure the contraction pressure. Diagnostic parameters were drawn out by analyzing the measured data. Statistical evaluations were done to classify the all subjects with five groups each has similar characteristics. SUI diagnostic algorithm was implemented to each group separately. The accuracy of the algorithm was about 78.9% and utility was confirmed by clinical trial.

Purpose: The purpose of this study was to analyze the relationship between lower urinary tract symptoms and urodynamic parameters to investigate the characteristics of mixed urinary incontinence (MUI) and stress urinary incontinence (SUI). Methods: The subjects were 318 women with MUI and 128 women with SUI. Data were collected retrospectively from electronic medical records including Bristol Female Lower Urinary Tract Symptoms-Scored Form (BFLUTS-SF), Incontinence Quality of Life Instrument (I-QOL), voiding diaries, and urodynamic parameters. Results: Compared with the SUI group, the MUI group was older and showed lower I-QOL and more severe urinary tract symptoms. The MUI group had more urinary frequency, more nocturia, and a higher urgency score than the SUI group. In the correlation analysis, the greatest difference between the two groups was that urgency was associated with Qmax, maximal cystometric capacity, and detrusor overactivity only in the MUI group (r = -.175, p= .004; r = -.281, p< .001; r= .232, p< .001, respectively). Conclusion: As a result of this study, we propose that a customized management program that emphasizes the control of urgency for the MUI group, and one that effectively strengthens the weak pelvic floor for the SUI group.

Purpose: This study was carried out to evaluate the efficacy of intravaginal pelvic floor electrical stimulation (FES) therapy on bladder irritability symptoms in stress urinary incontinent women. Materials and Methods: The evaluation before and after treatment included the Blaivas's female Bladder Questionnaire, the quality of life questionnaires and the overall satisfaction with present voiding state using visual analogue test (VAT). All patient were treated for 20 minutes, twice a week for 6 weeks, using a new intravaginal electrical stimulator with microchip (PIC16C74). Results: After the FES therapy, the overall success rate of the SUI was 50.4.% at 9 months. The bladder irritability symptoms such as frequency, nocturia, urgency, residual urine sensation and lower abdominal discomfort were improved. In particular, the symptoms of frequency, urge incontinence, dysuria were significantly improved after the FES therapy at 9 months. The VAT score of the overall satisfaction with the present voiding state was significantly lower after the FES therapy. 73.7% of patients were satisfied with the FES therapy and complications such as hemorrhage, vaginitis, urinary tract infection and pain were not encountered. Conclusion: These results suggest that FES therapy with microchip improves some bladder irritability in SUI women. Therefore, electrical stimulation therapy should be considered as a first line therapy in SUI women with bladder irritability symptoms.

Background: The purpose of this study was to determine the efficacy and safety of the anterior vaginal wall sling in the management of women with stress urinary incontinence. Materials and Methods: From January 1998 to December 1999, 42 patients(31 with genuine stress urinary incontinence and 11 with mixed urinary incontinence, 38 with anatomical incontinence and 4 with intrinsic sphincteric deficiency) underwent anterior vaginal wall sling at Yeungnam University Hospital were studied retrospectively. The mean age was 49.3 years(ranging from 34 to 66 years of age) and the mean follow-up period was 29.4 months(ranging from 16 to 40 months). Intra- and postoperative complication. success rate and patient's satisfaction were evaluated. Results: The mean operation time was 79 minutes(ranging from 65 to 124 minutes) and the mean hospital stay was 5.1 days(ranging from 4 to 10 days). Mean postoperative Foley catheter drainage was 2.1 days(ranging from 1 to 5 days). As a complication. bladder perforation occurred in one patient(2.4%). residual urine sensation developed in seven patients(16.7%), and suprapubic pain was complained in five patients(11.9%), which improved gradually. Vaginal epithelial inclusion cyst occurred in one patient(2.4%) at postoperative 31 months. Four(9.4%) patients with de novo instability were improved by anticholinergics medication. The success rate was 92.9% and 38 patients(90.5%) were satisfied with this procedure. Conclusion: We consider that the anterior vaginal wall sling to be a safe and effective surgical procedure for the treatment of female stress urinary incontinence, but a longer follow-up is necessary to determine long term effect.
