PURPOSE: The aim of the study was to evaluate the clinical outcome and complications of tension free vaginal tape (TVT) procedure for the surgical treatment of female stress urinary incontinence. MATERIALS AND METHODS: Between April 1999 and May 2000, 41 women with stress urinary incontinence underwent TVT procedure. Preoperative evaluation included questionnaires study, physical examination, one hour pad test and urodynamic study. Postoperative clinical outcome, patient's satisfaction and complications were checked after 3-months. RESULTS: The mean age of patients was 51.6 years (range 40-76) and mean hospital stay 2.1 days (range 1-10). The mean follow-up period was 9.9 months (range 3-15). Thirty six patients (87.8%) were cured, 2 patients (4.9%) were improved. Two of 3 patients with failed operation who developed postoperative urge incontinence had grade III cystocele. Five bladder perforations and 1 obturator nerve injury occurred. The abdominal leak point pressure (LPP) increased from 50.6cmH20 to 110.8cmH2O, detrusor pressure of maximal flow rate (Pdet.Qmax) increased from 15.8cmH2O to 28.6cmH2O and maximal flow rate (Qmax) decreased from 32.8ml/s to 22.5ml/s after operation. CONCLUSIONS: The TVT procedure is an effective and feasible surgical treatment for female stress urinary incontinence. However, in patients with grade III cystocele, postoperative urge incontinence may develop after the procedure. Since TVT procedure involves securing the mid-urethra, urinary obstruction may also occur, necessitating the need for continued follow-up as well as a careful comparison with other sling procedure.

PURPOSE: The aim of this study was to develop a baptist electronic Nutritional Screening Program (B-eNSP) that could be easily used to identify patients with nutrition at risk or malnutrition on their admission to hospital using an integrated medical information system and to evaluate validity, reliability and efficiency of B-eNSP. METHODS: From June 1 2009 to June 21 2009, we enrolled 496 patients for prospective research. We analyzed age, sex, weight, height, weight loss in the last 3 months, serum albumin, alteration of dietary intake, gastrointestinal symptom, functional capacity, diagnosis and its relationship to nutritional requirements, physical examination and Subjective Global Assessment (SGA). B-eNSP included body mass index (BMI), weight loss in the last 3 months, serum albumin. Each component was scored. Sensitivity and specificity were calculated to evaluate the validity of the B-eNSP. The receiver operating characteristic (ROC) curve was drawn by using B-eNSP to choose a cut-off value that maximizes sensitivity and specificity and Yoden Index. Comparison with SGA and the reliability of the B-eNSP was done using kappa statistics. RESULTS: The maximum Yoden Index was 0.866 and the cut-off value of the ROC curve was 2. A B-eNSP score higher than 2 was defined as nutrition at risk or malnutrition. Reliability of the B-eNSP was in accordance with SGA by kappa 0.845. CONCLUSION: The B-eNSP can be used efficiently to identify patients with nutrition at risk or malnutrition by simply using an integrated medical information system.

Background and Objectives:
Recurrence rates after radiofrequency catheter ablation (RFCA) in atrial fibrillation (AF) patients are not low especially in non-paroxysmal AF. The diameter of left atrium (LA) has been widely used to predict the recurrence after RFCA for decades. However, LA diameter represents structural remodeling of LA and does not reflect electrical remodeling. We aimed to determine the predictive value of electrical remodeling of LA which is represented by the amount of low voltage zone (LVZ).
Methods:
We performed a retrospective cohort analysis of AF patients who underwent de novo RFCA in a single-center.
Results:
A total of 3,120 AF patients with de novo RFCA were analyzed. Among these patients, 537 patients underwent an electroanatomic mapping with bipolar voltage measurement of LA.The diameter of LA and flow velocity of LA appendage (LAA) differed significantly according to quartile group of LVZ area and percentage: patients with high LVZ had large LA diameter and low LAA flow velocity (p<0.001). Freedom from late recurrence (LR) was significantly lower in patients with high LVZ area and percentage (p<0.001). The diameter and surface area of LA had area under curve (AUC) of 0.592 and 0.593, respectively (p=0.002 for both). The predictive value of LVZ area (AUC, 0.676) and percentage (AUC, 0.671) were both superior compared with LA diameter (p=0.011 and 0.027 for each comparison).
Conclusions
In conclusion, LVZ can predict freedom from LR after RFCA in AF patients. Predictive value was higher in parameters reflecting electrical rather than structural remodeling of LA.
