The Prevalence of Overactive Bladder Symptoms in Women in Algeria, Egypt, Jordan and Lebanon: A Cross-Sectional Population-Based Survey.

AIMS: Estimate the prevalence of symptoms suggestive of overactive bladder (OAB) in women living in the Middle East to describe their demographic characteristics and explore treatment-seeking behavior. METHODS: Cross-sectional, population-based survey of women aged ≥ 40 years resident in Algeria, Jordan, Lebanon or Egypt. Respondents were recruited using computer-assisted telephone interview over approximately 4 months. Eligible respondents were asked to complete the OAB-V8, a validated questionnaire that explores the extent of bother from the key symptoms of OAB without clinical investigations. In addition, information regarding demographics, comorbidities and treatment behavior was collected, and respondents were stratified by age. RESULTS: A total of 2297 eligible women agreed to participate. Mean age was 54 ± 10 years; over half (59.3%) were aged 40-55 years. Overall, 53.8% of eligible women had symptoms suggestive of OAB (Jordan 58.5%; Egypt 57.5%; Algeria 49.9%; Lebanon 49.0%), with over 90% also reporting symptoms of urinary incontinence. Only 13.0% of women with symptoms suggestive of OAB were currently receiving treatment, while most (74.3%) had never been treated; these data were consistent across country and age categories. Among the untreated subgroup, almost half (48.7%) reported they were 'not bothered by symptoms,' while 8.4% considered OAB to be 'part of normal aging' and 4.7% did not know it was treatable. CONCLUSION: A high prevalence of symptoms suggestive of OAB was observed, and the majority had symptoms of urinary incontinence. Despite the high prevalence, most women had never received treatment. Considering the potential significant impact of OAB symptoms on health, quality of life and productivity, these findings highlight an unmet medical need in the population studied. Strategies to improve treatment-seeking behavior (e.g., through education and tackling the stigma associated with OAB symptoms) may improve the diagnosis, management and health outcomes of women with OAB in the Middle East.

The effect of cortical versus sacral repetitive magnetic stimulation on lower urinary tract dysfunction in patients with multiple sclerosis.

75% of multiple sclerosis (MS) patients have lower urinary tract symptoms. Moreover, up to 80% of asymptomatic patients show abnormalities on urodynamic examination. The objective of this study is to assess the effect of repetitive magnetic stimulation on the motor cortex versus sacral roots in MS patients with lower urinary tract dysfunction (LUTD). 40 MS patients with LUTD were divided according to urodynamic studies (UDS) into two groups (20 patients each): Group A (overactive bladder) and Group B (underactive bladder). Each group was further subdivided into Subgroup (A-I) and (B-I) which received cortical magnetic stimulation and Subgroup (A-II) and (B-II) which received sacral magnetic stimulation. UDS, pelvic ultrasound as well as Incontinence Quality of Life (I-QOL) questionnaire were compared before and after magnetic stimulation sessions in each group as well as between groups. UDS showed significant reduction in bladder capacity, improvement in bladder contractility in all groups and subgroups. Moreover, it showed improvement of urine flow rate only in Group B. Reduction of post-void residual urine was noted in all subgroups except in (Group A-II). I-QOL questionnaire showed improvement in patients with underactive bladder only. Intergroup comparison between A and B showed no difference. Cortical as well as sacral magnetic stimulation showed significant effect on lower urinary tract dysfunction that led to improvement in symptoms in MS patients with underactive bladder, rather than those with overactive bladder.

A Prospective Evaluation of High-Resolution CT Parameters in Predicting Extracorporeal Shockwave Lithotripsy Success for Upper Urinary Tract Calculi.

OBJECTIVE: To evaluate the ability of noncontrast CT parameters (stone size, stone attenuation, and skin-to-stone distance [SSD]) to predict the outcome of extracorporeal shockwave lithotripsy (SWL) in a prospective cohort of patients with renal and upper ureteric stones. PATIENTS AND METHODS: Patients with stones 5 to 20 mm were prospectively enrolled from 2011 to 2014. Patients had NCCT with recording of stone size, stone mean attenuation, and SSD, as well as various stone and patient parameters. The numbers of needed sessions as well as the final outcome were determined, with SWL failure defined as residual fragments >3 mm. Predictors of SWL failure were assessed by multiple regression analysis. RESULTS: Two hundred twenty patients (mean ± standard deviation [SD] age 41.5 ± 12.4 years) underwent SWL. Mean ± SD stone size was 11.3 ± 4.1 mm, while mean ± SD stone attenuation was 795.1 ± 340.4 HU. Mean ± SD SSD was 9.4 ± 2.1 cm. The average number of sessions was 1.64. SWL was effective in 186 (84.5%) patients (group A), while 34 (15.5%) patients had significant residual fragments (>3 mm). On univariate analysis, predictors of SWL failure included stone attenuation >1000 HU, older age, higher body mass index, higher attenuation value, larger stone size, and longer SSD. Increased SSD and higher stone attenuation retained their significance as independent predictors of SWL failure (p < 0.05) on multiple regression analysis both after first session and as final SWL outcome. A positive correlation was found between number of SWL sessions and mean stone attenuation (r = 0.6, p < 0.001) and SSD (r = 4, p < 0.001). CONCLUSIONS: Stone mean attenuation and SSD on noncontrast CT are significant independent predictors of SWL outcome in patients with renal and ureteric stones. These parameters should be included in clinical decision algorithms for patients with urolithiasis. For patients with stones having mean attenuation of >1000 HU and/or large SSDs, alternatives to SWL should be considered.
