Simultaneous treatment of anterior vaginal wall prolapse and stress urinary incontinence by using transobturator four arms polypropylene mesh

PURPOSE: To evaluate the medium-term efficacy and safety of transobturator four-arm polypropylene mesh in the treatment of high-stage anterior vaginal wall prolapse and concomitant stress urinary incontinence (SUI). MATERIALS AND METHODS: Between September 2010 and August 2013, a prospective single-center trial was performed to evaluate women with stage≥3 anterior vaginal wall prolapse with or without SUI who presented to Labbafinejad Hospital, Teheran, Iran, and underwent anterior vaginal wall repair with polypropylene mesh. Pre- and postoperative evaluation included history; physical examination using the Pelvic Organ Prolapse Quantification system and cough stress test, both before and after reduction of prolapsed structures; Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ); urinalysis and culture; and a postvoid residual assessment. Complications were reported at a mean of 2 years of follow-up. RESULTS: A total of 71 patients underwent cystocele repair with the transobturator four-arm polypropylene mesh. Seven of the patients were lost to follow-up. There were no perioperative complications. The anatomical success rate was 87.5%. The subjective success rate was 92.1%. The PFDI and PFIQ were significantly improved after surgery (p<0.001). Among those with the simultaneous complaint of SUI, 82% were cured without any additional procedure. Three patients (4.6%) experienced vaginal mesh extrusion. Two patients (3.1%) reported worsening of dyspareunia after surgery. CONCLUSIONS: The four arms polypropylene mesh is an effective device for simultaneous correction of anterior vaginal wall prolapse and SUI with a low complication rate at a medium-term follow-up. The majority of the subgroup with concomitant SUI were cured without a second simultaneous procedure

Prevalence and risk factors of urinary incontinence among Iranian women

Background: Urinary incontinence is a common condition among women. Although it is not a life-threatening condition, it dramatically influences the quality of life. This study aimed to estimate the prevalence of urinary incontinence and its risk factors among Iranian women in Kerman, Iran. Methods: This cross-sectional, population-based study was conducted on 3100 Iranian women aged 15�80 years in 2017 in Kerman, Iran. The participants were selected via cluster sampling and were invited to complete the questionnaires. Their demographic information and medical history were assessed, the urinary incontinence questionnaire was completed, and the associated risk factors were also recorded. Quantitative variables are reported as mean ± SD, while qualitative and ranked variables are expressed in percentage. All analyses were conducted in Stata version 12 (Stata Corp.). Results: The mean age of the participants was 46 years, and the overall prevalence of urinary incontinence was estimated to be 63. The highest and lowest prevalence rates of urinary incontinence were reported in the elderly and the youth, respectively (79 and 41, respectively). Age, increase of body mass index (BMI), pregnancy, diabetes, anxiety, and depression were the associated risk factors. Conclusion: We found that the prevalence of urinary incontinence is high in Iran. Therefore, to control this condition and improve women's quality of life, effective plans are needed. © 2021 Wiley Periodicals LL

Equations for membrane transport. Experimental and theoretical tests of the frictional model.

Frictional models for membrane transport are tested experimentally and theoretically for the simple case of a solution consisting of a mixture of two perfect gases and a membrane consisting of a porous graphite septum. Serious disagreement is found, which is traced to a missing viscous term. Kinetic theory is then used as a guide in formulating a corrected set of transport equations, and in giving a physical interpretation to the frictional coefficients. Sieving effects are found to be attributable to entrance effects rather than to true frictional effects within the body of the membrane. The results are shown to be compatible with nonequilibrium thermodynamics. Some correlations and predictions are made of the behavior of various transport coefficients for general solutions
