Surgery may benefit women with two types of urinary incontinence


02 mar2009-- A transobturator tape procedure resulted in nearly an 80 percent improvement in urge urinary incontinence, according to research published in the March issue of Obstetrics & Gynecology. Samina Tahseen, of the Luton and Dunstable Hospital in Bedfordshire, United Kingdom, and a colleague conducted follow-up interviews, at a median of 13 months, on 58 women who had undergone a transobturator tape procedure. Based on diagnosis, women were categorized into three groups, either having stress incontinence only, mixed incontinence with predominant stress leakage, or mixed incontinence with predominant urge leakage. Overall, urge urinary incontinence was cured in 43 percent and improved in 36 percent, the researchers report. In the group of women with stress predominant leakage, incontinence was cured and improved in an equal proportion of patients (43.5 percent each). In women with urge predominant leakage, incontinence was cured in 43 percent and improved in 28.5 percent of patients, the investigators found. Stress incontinence was completely resolved in 77 percent and was improved in an additional 19 percent. No cases of de novo urge incontinence were reported, the authors note. "The transobturator midurethral sling has been shown in this study to improve urge urinary incontinence and overactive bladder symptoms significantly in mixed urinary incontinence and to provide high postoperative patient satisfaction," the authors conclude.
BIRMINGHAM, Ala., 29 jan 2009– Starting a weight-loss regimen significantly reduces urinary incontinence for women, according to researchers at the University of Alabama at Birmingham (UAB) and the University of California, San Francisco.
A six-month program of diet, exercise and behavior modification resulted in a loss of 17 pounds and nearly one-half (47 percent) fewer incontinence episodes per week on average, the study authors said.
By contrast, an information-only program on diet and exercise without any direct weight-loss training led to a loss of 3 pounds and 28 percent fewer incontinence episodes per week on average, the researchers said.
The results are published in the New England Journal of Medicine.
"Earlier research has shown that behavioral weight-loss programs have many benefits, including decreasing blood pressure and helping to fight off diabetes. Here we've shown that weight loss has measureable impact on reduced incontinence," said Frank Franklin, M.D., Ph.D., a UAB professor in the School of Public Health and a co-author on the NEJM study.
The NEJM results are from the Program to Reduce Incontinence by Diet and Exercise, or PRIDE study. It included 338 overweight and obese women (BMI 25-30 kg/m2) who experienced up to 10 episodes of incontinence per week.
Those on the diet, exercise and behavior modification program reported feeling significantly more satisfied with the improvements in incontinence compared to the information-only participants, Franklin said.
Urinary incontinence affects more than 13 million women in the United States and has been linked to increased risk of falls and bone fractures.
Considering the PRIDE results and other health benefits, the initiation of weight loss should be added as a first-line treatment in overweight and obese women, said lead study author Leslee Subak, M.D., of the University of California, San Francisco.
The study was a partnership with UAB, the University of California, San Francisco; Brown University in Providence, Rhode Island and the University of Arkansas for Medical Sciences in Little Rock. Funding is from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the Office of Research on Women's Health (ORWH), both part of the National Institutes of Health.
Two examples of anticholinergic drugs that are often prescribed for urinary incontinence are oxybutynin (Ditropan) and tolterodine (Detrol).
"Our high discontinuation rates across all anticholinergic drug classes...highlight the need for more effective therapies for lower urinary tract symptoms," Dr. Manish Gopal from Saint Peter's University Hospital, New Brunswick, New Jersey and colleagues conclude.
Using a large database, Gopal and colleagues analyzed 29,369 women aged 18 and older who were initially prescribed an anticholinergic medication, such as Ditropan or Detrol, between 1991 and 2005.
They found that half of women prescribed an anticholinergic stopped taking it by 6 months, and 3 out of 4 women discontinued therapy by 1 year. The median time to discontinuation for all 9 different anticholinergic drugs was about 4 months after initial use.
In a report in the journal Obstetrics and Gynecology, the investigators note that rates of discontinuation increased with duration of use, and "very few women" switched to another drug after initial prescribed treatment before stopping the drug.
Because of the high discontinuation rates of anticholinergic therapy for lower urinary tract symptoms, health care providers "must be vigilant" regarding alternative forms of treatment, such as bladder training and pelvic floor rehabilitation, for overactive bladder "and increase our awareness that this group of women is being treated inadequately," the investigators conclude.
