Impacts of Bariatric Surgery on Improvement of Incontinence Among Obese Asian Women: A Prospective Study and Literature Review

INTRODUCTION

Limited studies investigate bariatric surgery's role in improving UI status among Asians, specifically Middle Eastern Asian women. The aim of this study is to investigate the effect of bariatric surgery on the three most prevalent urine incontinence (UI).We also reviewed the current literature exploring the studies performed in Asian countries.

MATERIALS AND METHODS

A total of 77 women out of 200 who had UI and indications for bariatric surgery completed demographic information and the questionnaire (QUID) prior to surgery and 6 months after the surgery. For statistical analysis, the Mann-Whitney U test, Wilcoxon test, and Friedman test were utilized. We also performed a literature review with the aim of investigating studies performed in Asian countries.

RESULTS

Among the initial analysis of 200 participants, 50.5% reported UI symptoms before surgery. The average weight loss was 29 kg, with a standard deviation of 7 kg. The mean BMI dropped 11.2 kg/m2, and the standard deviation was 2.5 after weight loss. Post-surgery, significant reductions in UI scores were observed across all severity levels, with a notable 44% achieving complete symptom resolution, indicating a substantial decrease in urinary incontinence. Stress, urine incontinence, and mixed urine incontinence symptoms had improved in 75%, 71%, and 30% of women, respectively. Notably, age and gynecological history were identified as critical factors influencing the extent of UI improvement.

CONCLUSION

This study reveals significant improvements in urinary incontinence scores, with age and gynecological history playing pivotal roles in UI improvement.

Knowledge of pelvic floor disorders amongst immigrant women in Canada

INTRODUCTION AND HYPOTHESIS

Pelvic floor disorders (PFD) have a detrimental effect on quality of life. Despite the available treatments, women often do not seek medical care. Patient knowledge has been identified as a major barrier to accessing care. The objective of this study was to assess knowledge on PFD amongst women in Edmonton, hypothesizing that immigrant women are less knowledgeable about PFD than Canadian-born women.

METHODS

A cross-sectional study of immigrant women and Canadian-born women was conducted. Immigrant women were recruited at the Multi-Cultural Health Brokers Co-op (MCHB) and Canadian-born women at a colposcopy clinic. The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) was administered. Scores for UI and POP were calculated and compared using a Mann-Whitney U test and a t test. A subgroup analysis of immigrants was carried out according to length of stay in Canada and ethnicity. Ethics approval was obtained from the University of Alberta Human Research Ethics Office.

RESULTS

A total of 106 immigrants and 102 Canadian-born women completed the PIKQ. The overall PIKQ scores were 12.7 for immigrant women and 14.4 for Canadian-born women (p = 0.04). Immigrant women who had lived in Canada for >10 years had higher scores (mean = 13.2) compared with women with less than 10 years in Canada (mean = 11.8). Women from South Asia had higher overall PIKQ scores (mean = 14.6) whereas women from sub-Saharan Africa had the lowest scores (mean = 12.1).

CONCLUSIONS

Immigrant women in Edmonton were found to have less knowledge on PFD than Canadian-born women.

Association between Magnetic Resonance Imaging Findings of the Pelvic Floor and de novo Stress Urinary Incontinence after Vaginal Delivery

Objective

The study aimed to evaluate the contributions of levator ani muscle (LAM) injury, vesical neck movement, urethral length and mobility, and urethral sphincter dysfunction observed on magnetic resonance imaging (MRI) towards stress urinary incontinence (SUI) after vaginal delivery.

Materials and Methods

Fifty primiparous women after 6 months of delivery (15 with SUI and 35 without) and 35 nulliparous as continent controls underwent MRI at rest and Valsalva maneuver. A published levator ani scoring system was used to characterize morphological changes of LAM. The severity of the injury was divided into three categories as none, minor, and major. A series of common parameters including levator plate angle, iliococcygeal angle, and levator hiatus were used to describe the functional conditions of LAM. Urethral mobility was defined based on the rotation of the urethra between Valsalva and rest status. Vesical neck movement was evaluated by its distance to the pubococcygeal line. Urethral sphincter dysfunction was defined as the widening of the proximal urethra and/or funneling at the urethrovesical junction during Valsalva.

Results

Primiparous incontinent (PI) women had additional major levator ani defects (33.3% vs. 17.1%) while less minor defects (0.7% vs. 31.4%) than primiparous continent (PC) women. Vesical neck downward movement in PI women was more obvious than PC women (28.5 mm vs. 24.2 mm, p = 0.006). Urethral mobility was more active in primiparous women than in nulliparous continent controls (57.4 vs. 52.4), whereas no difference was observed on urethral mobility in the primiparous group (p = 0.25). Urethral sphincter dysfunction and funneling were present in 80% of PI women versus 22.9% in PC women (p < 0.001).

Conclusion

The MRI findings revealed that de novo SUI was associated with major LAM injury, vesical neck downward movement as well as urethral sphincter dysfunction. Vesical neck funneling on sagittal images can be treated as a valuable predictor for SUI. The intervention for the PI should focus on the elevation of vesical neck, rehabilitation of LAM as well as recovery of the urethral sphincter muscle.

MRI role in morphological and functional assessment of the levator ani muscle: use in patients affected by stress urinary incontinence (SUI) before and after pelvic floor rehabilitation

OBJECTIVE

Pelvic floor dysfunctions affect a very high proportion of female population. Magnetic resonance imaging is the only technique able to provide a multiplanar overview of pelvic organs and muscles without the use of ionizing radiation. The aim of our prospective study is to objectively evaluate the effectiveness of perineal re-education applying MR technique.

MATERIALS AND METHODS

22 patients affected by stress urinary incontinence were enrolled in our prospective study. They underwent urogynaecological, urodynamic examinations, and a questionnaire about symptoms (ICIQ-UI) to investigate the degree of their interference with daily activities. Then they underwent a morphological and dynamic MR exam.

RESULTS

The pre-perineal rehabilitation MR examinations showed an asymmetry of the levator ani muscle in 87% of patients; the remaining 13% showed a muscular bilateral volume reduction. In the group with unilateral defect, the muscle total volume had values between 15 and 21 cm3. Its overall volume was 34.2% smaller on the defective side (9.28±0.26 cm3) compared to the normal side (12.64±12.31 cm3, P<0.001). In patients with a bilateral impairment, the muscle was replaced by fibro-fatty tissue, without a significant asymmetry between the two sides. The post-perineal rehabilitation MR tests showed three different degrees of response to therapy, with a "complete response" found in 67% of patients and no response in 13%.

CONCLUSIONS

MR is an useful tool in the management of patients affected by stress urinary incontinence with indication for perineal rehabilitation. Its objective data allow to distinguish different types of response to therapy and, consequently, different outcomes in terms of additional treatments.
