Abstract
Background
It is well known that morbid obesity in women is related to lower urinary tract symptoms,
including urinary incontinence. Although several studies have reported on the improvement
in urinary incontinence after bariatric surgery, few reports have focused on the detailed
changes in other voiding characteristics.
Objective
To demonstrate the real benefit of bariatric surgery on lower urinary tract symptoms.
Setting
Bariatric Center of Excellence and Health Promotion at Soonchunhyang University Hospital.
Methods
From August to December 2012, a total of 57 women out of 183 women who underwent bariatric
surgery agreed to be assessed for voiding dysfunction during their preoperative and
1-year postoperative evaluation using the international prostate symptom score, quality
of life score, an overactive bladder symptom score, a patient perception of bladder
score, and a Sandvick questionnaire for urinary incontinence. For statistical analysis,
the Wilcoxon sign rank and Fisher׳s exact tests were used to assess a significant
change in voiding status.
Results
Among a total of 183 women in the bariatric center, 57 women completed the full version
of the urologic questionnaire. The baseline mean age of those patients was 38.5±9.5
and their baseline mean body mass index (BMI) was 37.5±5.9 (68.4% were over BMI 35).
One year after bariatric surgery (Roux-en-Y gastric bypass), BMI showed a significant
change, 9.5±3.5 (63.1% were below BMI 28). For specific characteristic changes in
voiding status, the international prostate symptom score, quality of life score, overactive
bladder symptom score, and patient perception of bladder score revealed significant
improvement over baseline: 3.2±4.0, .6±.9, 1.6±2.3, and .5±1.0, respectively. For
stress-related urinary incontinence as assessed using the Sandvick questionnaire,
preoperative evaluation demonstrated the prevalence to be 40.74%, and 18.51% postoperatively.
Conclusion
At a 1-year postoperative follow-up after laparoscopic gastric bypass-type bariatric
surgery, there were significant improvements in voiding status as assessed by several
standard urologic voiding questionnaires/indices.
