The epidemiology of urinary dysfunction in Chinese women

The epidemiology of urinary dysfunction in a Chinese population living in Hong Kong was investigated. Fifteen hundred ethnic Chinese women answered a telephone questionnaire including symptoms of urinary dysfunction, anthropometric measurements, obstetric history and place of birth. The relative predictive value of these factors was analyzed using logistic regression. The prevalence of urinary dysfunction was 13%. Ten percent reported stress incontinence, and 4% had urgency or urge incontinence. The strongest predictor was place of birth, with women born in mainland China having the highest prevalence of pure stress incontinence (OR 1.33, CI 1.1–1.6). For the symptoms of detrusor instability age was the strongest predictor, with women over 50 years being at greater risk (OR 2.8, CI 1.6–5.0). Contrary to earlier beliefs, urinary dysfunction in Chinese women is as common as in Caucasian women. Place of birth is the strongest predictor for pure stress incontinence, with women born in mainland China being at greater risk. This suggests that environmental factors in early life have a differential effect on the development of urinary incontinence. EDITORIAL COMMENT: Taiwan Chinese women have a comparable prevalence of urinary dysfunction with Hong Kong Chinese women. A survey representing a multistage sample of 82 678 women aged 18 years or older was conducted in the Taipei area from January to June 1993. A total of 818 cases were interviewed by trained students. One hundred and eighty-nine (23.1%) of the respondents reported having had some degree of incontinence in the preceding 12 months, 28 (3.4%) reporting regular incontinence. Most presented with stress urinary incontinence, whereas urge incontinence and mixed incontinence were more commonly seen in the elderly group (aged 60 years or older). The risk factors for urinary incontinence included age, number of vaginal deliveries (>3), number of abortions (>2) and maternal history of incontinence. Voiding symptoms (irritative or obstructive) and constipation were significantly more prevalent among respondents with incontinence than those without (P<0.001). This evidence also indicates that the long-held belief that Chinese women have a much lower prevalence of urinary dysfunction than western women has all but ended.     

The prevalence of adult female urinary incontinence in Hong Kong Chinese

This was a community-based study to evaluate the prevalence and characteristics of female urinary incontinence in women aged 18 and above in the Shatin District of Hong Kong. Of a total of 1018 female households contacted, 362 individuals were successfully interviewed and 123 women (34%) reported they had experienced at least one episode of urinary incontinence as adults. Of these, 18.5% reported persistent incontinence and 15.5% reported absence of incontinence after a single episode of urine loss. The risk factors for incontinence revealed by this study were body mass index and parity. Women who had never been incontinent had a lower body mass index and were usually nulliparous. Most of the respondents (43.9%) who had urinary incontinence considered the condition to be a minor problem and did not seek professional advice. This investigation indicates that a territory-wide study should be carried out to determine the incidence of urinary incontinence throughout Hong Kong. EDITORIAL COMMENT: This article deals with a field study on the prevalence of urinary incontinence in a certain area of Hong Kong. There have been numerous articles on this subject from both occidental and oriental countries. As far as I can see, there is nothing new in respect of the prevalence and characteristics of those who lose or do not lose urine, but it is of interest to read the first formal study on a Chinese female population conducted by Chinese doctors. This clearly shows that prevalence in the Chinese population is essentially no different from that reported from other countries, and that the previous suppression of a lower incidence in the Chinese population was an error.     

Neuromodulation for the treatment of urinary incontinence

Abstract:   Neuromodulation has been reported to be effective for the treatment of stress and urgency urinary incontinence. The cure and improvement rates of pelvic floor neuromodulation in urinary incontinence are 30–50% and 60–90%, respectively. In clinical practice, vaginal, anal and surface electrodes are used for external, short-term stimulation, and sacral nerve stimulation for internal, chronic (long-term) stimulation. The effectiveness of neuromodulation has been verified in a randomized, placebo-controlled study. However, the superiority to other conservative treatments, such as pelvic floor muscle training has not been confirmed. A long-term effect has also been reported. In conclusion, pelvic floor exercise with adjunctive neuromodulation is the mainstay of conservative management for the treatment of stress incontinence. For urgency and mixed stress plus urgency incontinence, neuromodulation may therefore be the treatment of choice as an alternative to drug therapy.     

Relationship between Stress Urinary Incontinence and Pelvic Organ Prolapse

We investigated the objective coexisting rate of stress urinary incontinence and pelvic organ prolapse, and also compared the treatment outcomes in patients who had both conditions, treated by a corrective operation on the basis of a precise preoperative evaluation. We reviewed 97 cases who underwent urodynamic studies and evaluation of the prolapse according to the Pelvic Organ Prolapse Quantification (POP-Q) system from among patients who were admitted for treatment of either stress urinary incontinence or pelvic organ prolapse. A Burch urethropexy, either alone or with a parvaginal repair, was done to correct the stress urinary incontinence, as well as additional operations to correct prolapse of stage II or more. The patients were evaluated postoperatively for the stress urinary incontinence and the degree of prolapse at every visit. Nineteen of 30 (63.3%) patients who were admitted with stress urinary incontinence had a coexisting pelvic organ prolapse, most often of the anterior wall. In 42 of 67 (62.7%) cases admitted with pelvic organ prolapse there was a coexisting stress urinary incontinence. A total of 61 patients who had both conditions were followed for 12 months postoperatively. The recurrence rate of stress urinary incontinence and prolapse (all of which were stage II) was 3.3% and 18.0%, respectively. It was noted that the greater the preoperative stage, the higher the recurrence rate (stage II 4.35%; stage III 25.0%; stage IV 33.6%). The coexisting rates of pelvic organ prolapse in patients having stress urinary incontinence, and stress urinary incontinence in patients having a pelvic organ prolapse, were both high. Therefore, when a preoperative evaluation that simultaneously considers both conditions and the correcting surgery is based on this evaluation, the recurrence rates of both conditions could be lowered.     

Prospective multicenter clinical trial of Uretex Sup for surgical treatment of stress urinary incontinence

AIM: To evaluate in a prospective multicenter study the efficacy and safety of the suburethral support Uretex (Sofradim, Trevoux, France) delivered by a suprapubic approach in the treatment of female stress urinary incontinence. METHODS: Between March 2002 and March 2003, 57 patients were treated for stress urinary incontinence with Uretex. Preoperative evaluation included urodynamic examination and questionnaires (symptoms and quality of life, Contilife). Forty patients had pure stress urinary incontinence and 17 mixed urinary incontinence. No associated procedure was performed. The objective cure rate was evaluated by clinical examination and pad-test, and the subjective cure rate was assessed through questionnaires at 1, 3 and 12 months. RESULTS: The mean follow-up was 13 months (range 11-24 months). During follow up, chronic urinary retention requiring a tape section occurred in one patient, and in another patient a delay of vaginal healing was followed by a sling exposure and resection at 4 months. No infection or urethral erosion was reported. The objective cure rate was 96.2%, and the subjective cure rate was 79.2%; four patients reported low leakage on stress and nine patients complained of urge incontinence (four de novo and five persistent). CONCLUSION: The suprapubic Uretex Sup procedure is a safe and effective treatment for women with stress urinary incontinence.     

Changes in urodynamic measurements after successful anal electrostimulation in female urinary incontinence

Fifty-five of 71 women with stress, motor urge and mixed stress and motor urge urinary incontinence were treated successfully with a new integrated electrostimulation device (Incontan) used anally. Changes in urodynamic measurements were evaluated when the patients themselves reported cure or significant improvement. The duration of the treatment was 9 to 20 h/day for at least 2 months (mean 9 months). According to the patients' subjective evaluation, 71% were cured of their incontinence and 29% were markedly improved. In motor urge and mixed incontinence a significant increase in bladder volume at first sensation and at maximum cystometric capacity was found, and 45% of these patients had a normal, stable bladder after treatment. A significant increase in functional urethral length was observed in patients who had had stress incontinence, but the measured increase in maximum urethral pressure was not significant. Of the 16 patients with stress and mixed incontinence who reported cure, 15 had a positive urethral closure pressure during coughing after treatment. Urodynamic analysis confirmed the positive clinical effect observed after electrostimulation therapy. It is recommended as primary therapy in stress, motor urge and mixed stress and motor urge incontinence in women.     

Urinary incontinence--prevalence, impact on daily living and desire for treatment: a population-based study

OBJECTIVE: To investigate the prevalence of urinary incontinence in a representative population in Sweden, and to assess to what extent the condition affects daily life and to what degree those afflicted desire treatment. MATERIAL AND METHODS: In a population-based study, a postal questionnaire comprising 12 questions on urinary incontinence was sent to a representative sample of 15 360 randomly selected residents (aged 18-79 years) of Orebro County, Sweden. This was a supplement to a comprehensive survey of public health and general living conditions. RESULTS: The response rate was 64.5%. The prevalence of urinary incontinence was 19% when defined as "any leakage" and 7% when defined as "at least once a week". Women were more afflicted than men, and the proportion of people with urinary incontinence increased markedly with increasing age. Most considered their problems to be minor, having little impact on daily life, which was reflected by the fact that only 18% of those with urinary incontinence desired treatment. About 17% of those with urinary incontinence reported severe problems that interfered with daily life. Of respondents with severe problems, 42% did not want treatment. CONCLUSION: According to this population-based study, urinary incontinence is not a major problem for most people in the community. Although a considerable proportion of the population report urinary incontinence, the majority experience minor problems and only 18% desire treatment. For a limited group of people, urinary incontinence is a severe problem. It is important that healthcare resources are optimized to identify and meet the needs of those who are most afflicted.     

Urinary incontinence: occurrence, knowledge, and attitudes among women aged 55 and older in a rural Midwestern setting.

OBJECTIVE: To examine the occurrence, attitudes, and knowledge of urinary incontinence (UI) among older women in a rural setting. DESIGN: Client questionnaire. SETTINGS AND SUBJECTS: A randomly selected sample of community-dwelling women aged 55 years and older living in a rural midwestern state. INSTRUMENT: Participants completed several instruments, including an Incontinence Survey that queried primarily demographic data, an Incontinence Quiz that queried knowledge and attitudes toward UI, and specific questions related to its clinical and psychosocial consequences. METHODS: The questionnaire was mailed to 300 women whose names had been randomly selected from a seniors' group mailing list. MAIN OUTCOME MEASURE: The prevalence of UI among a group of community-dwelling older women as well as attitudes and knowledge concerning incontinence. RESULTS: One hundred twenty women returned the questionnaire, providing a response rate of 40%. Three of the 120 respondents were excluded because they did not answer the question pertaining to UI status. Of the 117 who did respond, 79 (67.5%) reported UI. Most of the respondents with incontinence categorized their UI as minor (81.9%), and 88% denied that incontinence had a significant impact on their lifestyle. Thirty-seven percent of the incontinent women sought treatment. When questioned about UI, over half of the 117 respondents incorrectly indicated that incontinence is a normal result of advanced age. Almost one third of the respondents incorrectly believe that most people become incontinent by the time they reach the age of 85. CONCLUSIONS: Misconceptions concerning the causes of and the availability of treatment for incontinence among community-dwelling women may have an impact on their decision to seek care for this typically remediable condition.     

Prevalence of anal incontinence in 409 patients investigated for stress urinary incontinence.

A clinical questionnaire concerning anorectal symptoms and urodynamic tests was used to investigate 409 women consulting for stress urinary incontinence. To compare urodynamic data, patients were divided into three groups of women who had either stress urinary incontinence associated with incontinence for formed and/or liquid stools or with gas incontinence, or isolated stress urinary incontinence. To take in account the patients'age for data interpretation, a Mantel-Haenszel test or covariate analysis was performed. Anal incontinence was reported in 114 (28%) of the 409 women investigated. The prevalence of incontinence for gas only, for liquid, or for solid stools was 18.3, 9.3, and 1%, respectively. The duration of gas incontinence was longer than that of fecal incontinence or stress urinary incontinence. Difficult defecation was more frequently observed in patients with double incontinence than in patients with only stress urinary incontinence, and the difference was significant between patients with gas incontinence and patients with stress urinary incontinence (53% versus 37%, P = 0. 03). There was no difference in the number of bowel movements per week among the three groups of patients. The number of vaginal deliveries was surprisingly lower in patients with fecal incontinence associated with urinary incontinence than in others. There was no urodynamic feature that could distinguish patients with urinary incontinence and patients with double incontinence. This study confirmed the close relationship between anal and stress urinary incontinence. Neurourol. Urodynam. 18:579-590, 1999.     

Combined cystourethropexy for the treatment of type 3 and complicated female urinary incontinence

We treated 37 women with type 3 stress urinary incontinence or with an associated complicating factor, such as morbid obesity, a large or proximal diverticulum or a urethrovaginal fistula, via combined transvaginal cystourethropexy. All women with type 3 stress incontinence had failed a previous anti-incontinence operation. Patients in both groups underwent suprapubic needle suspension and an additional bladder neck support procedure. Among 33 patients who underwent preoperative urodynamic studies 30 had stable bladders (90%), while 3 had low pressure detrusor instability (10%). The success rate in achieving continence, including cured and improved patients, was 94.6% with a followup of 3 to 72 months. Four patients (10%) required temporary intermittent catheterization for 3 to 4 weeks but none presented with long-term voiding dysfunction. The added bladder neck support improved our results in these complicated female incontinence cases compared to the standard suprapubic needle suspension procedures alone. The combined procedure currently is our method of choice for treatment of type 3 and other complicated cases of female urinary incontinence.     

The treatment of male stress urinary incontinence with polydimethylsiloxane in compliant bladders following spinal cord injury

STUDY DESIGN: Retrospective analysis. OBJECTIVES: To evaluate the safety and efficacy of polydimethylsiloxane (PDS, Macroplastique) submucosal injections, in the treatment of male genuine stress urinary incontinence secondary to spinal cord injury (SCI). SETTING: London Spinal Injuries Unit, Stanmore, UK and Institute of Urology and Nephrology, London, UK. PATIENTS AND METHODS: A retrospective analysis identified 14 patients treated with PDS for stress urinary incontinence secondary to SCI between 1997 and 2001. A single surgeon at a specialist spinal injuries unit managed all patients. A total of 13 patients had suffered a traumatic SCI (T11:n=2; T12:n=5; L1:n=5; L2:n=1), while one developed stress incontinence after spinal surgery. The mean age was 41 years (range 26-69 years) and the mean duration of injury was 9.6 years (range 1.5-48 years). The preoperative investigations included video cystometrogram (VCMG) confirming the presence of urodynamically proven stress incontinence without evidence of urge incontinence. Complete cure was defined as a cessation of pad usage with no evidence of leakage on VCMG. Incomplete cure with improvement was defined as a >50% reduction in the number of pads used, with incontinence present on VCMG. RESULTS: The follow-up ranged from 12 to 58 months (mean 34.7 months). Five patients (36%) reported complete success, confirmed by VCMG. Three patients (21%) reported improvement with >50% reduction in the use of pads. The procedure failed completely in six patients (43%). No immediate or late complications were noted with the procedure. CONCLUSIONS: The use of PDS is a safe and minimally invasive treatment for genuine stress urinary incontinence in males following SCI with a stable compliant bladder. We achieved complete cure in 36% of our patients with confirmation on VCMG. A further 21% reported greater than 50% reduction in usage of pads; however, on VCMG stress incontinence was demonstrated in these patients. We suggest that PDS can be used as the first line of treatment in this difficult group of patients with complex problems.     

Surgical management of stress urinary incontinence: a questionnaire based survey

OBJECTIVES: To determine the trends in the surgical management of urinary stress incontinence amongst members of the International Urogynaecology Association (IUGA). DESIGN: Postal Questionnaire Survey. METHODS: 530 members of the International Urogynaecology association were sent a postal questionnaire regarding their practice in the surgical management of urinary stress incontinence. We also collected data on the demographic profile of members and the preferred primary and secondary continence procedures. OUTCOME: Consensus in the surgical management of urinary stress incontinence amongst members of the IUGA. RESULTS: Five hundred and thirty questionnaires were sent to IUGA members worldwide. Two hundred and seventeen questionnaires were received of which fifteen were from physiotherapists, so were excluded from our analysis. The overall response rate was 41%, and the useable response rate was 38%. Of the total results analysed (two hundred and two), one hundred and twelve (54%) were from teaching hospital, sixty-two (31%) were from district general hospitals and twenty-eight (14%) were from members in private practice. The preferred primary continence procedure was Tension Free Vaginal Tape (TVT) in one hundred and thirty four (68%) respondents. The preferred secondary continence procedure was colposuspension or Trans obturator tape in twenty-six respondents each (13%). CONCLUSIONS: Almost all respondents (97.1%) were skilled at performing either TVT or colposuspension, which have been identified as the preferred methods of surgical management by the NICE (National Institute of Clinical Excellence, UK). Although colposuspension has been identified as the gold standard surgical procedure in the management of stress incontinence, 16% of respondents were not performing colposuspension. There appears to be little evidence base to the surgical techniques in the management of stress urinary continence.     

Comparative analysis of urinary incontinence severity after autologous fascia pubovaginal sling, pubovaginal sling and tension-free vaginal tape

PURPOSE: Autologous fascia, Pelvicol implant and polypropylene are common materials used in suburethral anti-incontinence procedures. We explored the relative effectiveness of the autologous fascia pubovaginal sling, Pelvicol pubovaginal sling and Gynecare TVT on self-reported postoperative urinary incontinence. MATERIALS AND METHODS: The study was a mailed cross-sectional survey of health related quality of life 1 to 3 years after suburethral anti-incontinence surgery performed at our institution. The Incontinence Symptom Index was used to assess the presence and severity of urinary incontinence symptoms and the Incontinence Impact Questionnaire-7 was used to assess impairment. Regression models were developed to identify factors with an independent effect on the presence, severity and impairment of urinary incontinence symptoms. RESULTS: The questionnaire was returned by 69% of eligible respondents (173 of 250). Those with previous incontinence surgery (OR 11.0, 95% CI 2.3-51.4) and medical comorbidities (OR 1.6, 95% CI 1.1-2.2) were more likely to report urinary incontinence symptoms, ie incontinence symptom index greater than 0. Symptom severity, which was analyzed only in respondents with urinary incontinence symptoms, was greater in the Pelvicol than in the autologous fascia pubovaginal sling and TVT groups (each p <0.01). No significant difference was observed between the TVT and autologous fascia pubovaginal sling groups (p = 0.15). Also associated with higher urinary incontinence symptom severity scores were body mass index (p = 0.03), a history of incontinence surgery (p = 0.01) and lower education (p <0.01). Impairment from urinary incontinence, as assessed by the Incontinence Impact Questionnaire-7, was associated with body mass index, severe depression and current smoking (each p = 0.01) but not with surgical treatment group. CONCLUSIONS: Women who received an autologous fascia pubovaginal sling or TVT reported lower symptom severity scores than those who had a Pelvicol pubovaginal sling. Impairment was not associated with procedure type. These findings suggest better outcomes with autologous fascia pubovaginal sling and TVT. Randomized, controlled trials are needed to confirm these findings.     

The prevalence of urinary incontinence among community dwelling men: results from the National Health and Nutrition Examination survey

PURPOSE: To measure the prevalence of urinary incontinence in community dwelling men in the United States, we analyzed data from respondents to the National Health and Nutrition Examination Survey. MATERIALS AND METHODS: From 1999 to 2000 the National Health and Nutrition Examination Survey asked a national sample of community dwelling men, "In the past 12 months, have you had difficulty controlling your bladder, including leaking small amounts of urine when you cough or sneeze?" Questionnaire results were recorded and analyzed with respect to demographic data, and compared to the National Health and Nutrition Examination Survey data in women. RESULTS: The overall prevalence of urinary incontinence in men was 17%. Prevalence increased with age from 11% in men 60 to 64 years old to 31% in men 85 years old or older. Of the men reporting any incontinence 42% reported daily incontinence and 24% reported it weekly. Black men had the highest prevalence of male incontinence (21%) and black women had the lowest prevalence of female incontinence (20%). While the prevalence of incontinence in black women was virtually the same as that in black men, the prevalence of incontinence in white and Mexican-American women was at least 2.5 times that of men of the same ethnicity. CONCLUSIONS: The National Health and Nutrition Examination Survey draws a nationally representative sample of subjects from the community and, thus, provides prevalence data for urinary incontinence for all men in the United States. Ethnicity appears to be a contributing risk factor for incontinence, although racial patterns clearly differ between men and women.     

The prevalence of urinary incontinence in women in four European countries

OBJECTIVE: To determine the prevalence, type and treatment behaviour of women with urinary incontinence in four European countries. SUBJECTS AND METHODS: Data were collected using a postal survey which was sent to 29,500 community-dwelling women aged > or = 18 years in France, Germany, Spain and the UK. Subjects were asked about the type of urinary incontinence they had experienced and their treatment behaviour. RESULTS: Of the women who responded, 35% reported involuntary loss of urine in the preceding 30 days; stress urinary incontinence was the most prevalent type. The lowest prevalence was in Spain (23%), while the prevalence was 44%, 41% and 42% for France, Germany and the UK, respectively. About a quarter of women with urinary incontinence in Spain (24%) and the UK (25%) had consulted a doctor about it; in France (33%) and Germany (40%) the percentages were higher. Overall, <5% of the women had ever undergone surgery for their condition. While pads were used by half of the women, there were some differences among the countries. CONCLUSIONS: Millions of women in Europe have urinary incontinence; the consultation and treatment rates were low in the European countries included in this study.

The physical finding of stress urinary incontinenceamong African women in Ghana

The aim of this study is to determine the proportion of women with the physical sign of stress urinary incontinence in a sample of Ghanaian women. Two hundred randomly selected women from attendants at a convenience selected ultrasound clinic were interviewed about symptoms of urinary incontinence. A paper towel test was performed to objectively demonstrate the physical sign of stress urinary incontinence as leakage on coughing. Forty-two percent of the women had a positive paper towel test. The two major symptoms reported by the women with positive paper towel test were (1) loss of urine while waiting to use the toilet (48.2%) and (2) loss of urine on coughing (43.4%) in daily life. The physical sign of stress urinary incontinence could be present in up to 42% of Ghanaian women.     

Efficacy of the InVance male sling in men with stress urinary incontinence

OBJECTIVES: To evaluate the efficacy and safety of the InVance bulbourethral sling in male stress urinary incontinence. MATERIALS AND METHODS: Between June 2003 and April 2005, the InVance bulbourethral sling was implanted into 50 patients with urinary incontinence after prostate surgery in 49 cases and pelvic trauma in 1 case. The patients were monitored and evaluated in a prospective manner (continence, tolerance, and satisfaction). The treatment was considered to be successful if the patient stopped wearing any kind of continence pad (patient cured) or only one pad per day (patient improved), with no de novo urinary disorders and without significant postvoid residual urine. Patient satisfaction with the procedure was assessed. RESULTS: After a median follow-up of 6 mo, 50% of patients were dry, 26% had improved, and 24% suffered treatment failure. The success rates for the patients with severe incontinence and those who had undergone radiation therapy were 50% and 25%, respectively. All patients who were dry or had improved were satisfied and presented no obstructive or irritative de novo urinary disorders. The overall success rate for the 51 procedures conducted was 74.5%. Six cases of transitory acute urine retention and six cases of persistent perineal pain were reported. Explantation was necessary because of suppuration of the sling in three patients and of a de novo irritative urinary disorder in one patient. No cases of pubic osteitis or urethral erosion were reported. CONCLUSIONS: The InVance bulbourethral sling procedure makes it possible to treat stress urinary incontinence after prostate surgery with satisfactory and lasting short-term results. Severe incontinence and a past history of pelvic radiation therapy seem to be factors contributing to the failure of this procedure.     

Bariatric surgery improves urinary incontinence in morbidly obese individuals

BACKGROUND: Urinary incontinence is common in obese individuals. We report on the prevalence of urinary incontinence in patients undergoing bariatric surgery and the effect of surgically induced weight loss on urinary incontinence. METHODS: The prospectively collected data from 201 consecutive candidates for bariatric surgery were evaluated. The patients were surveyed using a questionnaire regarding the duration of incontinence, stress/urge incontinence symptoms, and incontinence severity before and after undergoing bariatric surgery. Severity was quantified using a validated index developed Data are presented as the mean +/- standard deviation. RESULTS: Of 201 patients, 65 (32%) reported urinary incontinence. Of the 65 patients, 44 women and 1 man (age 49 +/- 11 years, body mass index 48 +/- 7 kg/m(2)) underwent Roux-en-Y gastric bypass (n = 42) or laparoscopic-assisted gastric banding (n = 3). Of the 38 patients who reported mild (2%), moderate (48%), and severe (50%) urinary incontinence preoperatively who had complete follow-up at > or = 6 months postoperatively, 19 (50%) had demonstrated resolution of urinary incontinence and 19 had reported residual slight-moderate (37%) or severe (13%) urinary incontinence. The overall severity score improved from 5.4 +/- 2.3 to 2.3 +/- 2.8 postoperatively (P <.001); the percentage of excess body weight loss was 61% +/- 19%. The patients reported subjective improvement within 4 months postoperatively or after a 50-lb weight loss. CONCLUSION: Urinary incontinence is prevalent in bariatric surgery patients. Surgically induced weight loss results in improvement or resolution of urinary incontinence in 82% of patients. The findings from this large cohort warrant additional investigation with urodynamic studies.
