Sphincteric urinary incontinence: relationship of vesical leak point pressure, urethral mobility and severity of incontinence.

PURPOSE: We examined the relationships among urethral hypermobility, intrinsic sphincter deficiency and incontinence in women. MATERIALS AND METHODS: A total of 65 consecutive women with stress urinary incontinence and 28 with lower urinary tract symptoms not associated with stress urinary incontinence were evaluated with videourodynamics, 24-hour voiding diaries and pad tests, vesical leak point pressure measurement and the cotton swab test. RESULTS: A total of 93 patients with a mean age +/- SD of 63 +/- 13 years were studied, including 65 who presented with stress urinary incontinence and 28 who presented with lower urinary tract symptoms without stress urinary incontinence. The incidence of urethral hypermobility was 32% in the stress urinary incontinence group and 36% in the lower urinary tract symptoms group (p = 0.46). When stress urinary incontinence cases were stratified according to a vesical leak point pressure of 0 to 60, 60 to 90 and greater than 90 cm. H2O, urethral hypermobility was noted in 25%, 31% and 41%, respectively, a difference that was not statistically significant (p = 0.6). Overall incontinent patients with and without urethral hypermobility had the same median number of incontinence episodes (5, range 1 to 13 versus 7, range 1 to 15, p = 0.39) and median pad weight (39.5 range 1 to 693 gm. versus 33.5, range 1 to 751, p = 0.19). When patients with intrinsic sphincter deficiency, defined as vesical leak point pressure less than 60 cm. H2O, were divided into those with and without urethral hypermobility, there were no differences in the mean number of incontinence episodes (9.4 +/- 3 versus 6 +/- 3.6, p = 0.17) or median pad weight (90 gm., range 10 to 348 versus 86, range 30 to 81, p = 0.76). The degree of change in the urethral angle did not correlate with vesical leak point pressure (r = 0.16, p = 0.24) or with pad weight (r = -0.23, p = 0.1). CONCLUSIONS: Urethral hypermobility was equally common in this group of women with lower urinary tract symptoms and stress urinary incontinence. Intrinsic sphincteric deficiency and urethral hypermobility may coexist and they do not define discrete classes of patients with stress urinary incontinence. Urethral hypermobility did not appear to have an independent effect on the frequency or severity of incontinence. Patients with stress urinary incontinence can still be characterized by vesical leak point pressure and change in the urethral angle, although these variables do not always define discrete classes.

Effects of pelvic floor exercises in middle aged women with a history of naïve urinary incontinence: a population based study.

OBJECTIVE: To follow the effect of a 4-month pelvic floor exercise (PFE) program in women with naïve urinary incontinence with vaginal electromyography (EMG), pressure and palpation and also to compare the initial findings with symptom-free women of the same age. METHODS: The pelvic floor function expressed with vaginal EMG, pressure and palpation was measured before, during and after 4 months of PFEs in 60 previously untreated incontinent women, 50 of whom completed the study. The patients' perception of the situation and the amount of leakage were estimated before and after PFE. The incontinent group was compared at baseline and after PFE with 28 healthy controls. All women in this study (age 53-63) were randomly recruited from a major population based study. RESULTS: At baseline, the incontinent women had significant reductions of both vaginal EMG activity and pelvic floor muscle condition as estimated by palpation compared to the healthy group. During training a successive, significant increase was seen in both EMG, pressure and palpation and the values eventually exceeded those of the healthy women. The measures reflecting improvement of pelvic floor function thus showed a consistent and progressive pattern. The degree of improvement was higher in those with initial high values in the muscle function tests than in the women with lower initial EMG values, pressures and findings on palpation. No differences were seen between patients with a history of stress incontinence and patients with an urge component, i.e. urge or mixed incontinence. Sixty-four percent of the women were satisfied and wanted no further treatment. The median leakage at pad-test decreased from 5 (range 0-328) to 1 (range 0-126) g/24h. The correlation between the vaginal and the pad-test measurements was weak. CONCLUSION: Women with urinary incontinence have a significant reduction of pelvic floor function as estimated with vaginal EMG and palpation as compared to symptom-free controls. A successive normalization of vaginal EMG, pressure and findings at palpation was seen during the 4-month training period. Incontinence of both stress type and with an urge component can be alleviated in most of the women with PFE. These methods might be useful for routine evaluation of the pelvic neuromuscular disorder present in incontinent women.

Collagen injection therapy for post-prostatectomy incontinence.

PURPOSE: Post-prostatectomy incontinence has an incidence of 5 to 12% and greatly affects quality of life. Since the approval of glutaraldehyde cross-linked collagen there is a renewed interest in injectable urethral bulking agents. We investigated the long-term efficacy and prognostic criteria for transurethral collagen injection therapy for men with post-prostatectomy incontinence. MATERIALS AND METHODS: From November 1993 to May 1995, 62 men with post-prostatectomy incontinence (54 after radical prostatectomy and 8 after transurethral resection of the prostate) were treated with collagen via a transurethral approach. Median followup was 29.0 months from the date of the last injection procedure. RESULTS: Social continence was defined as dry or minimal leakage requiring at most 1 pad daily with activity. Of 62 patients 38.7% achieved social continence and 8.1% became totally dry. The success rate was 35.2 for radical prostatectomy versus 62.5% for transurethral prostatic resection patients. Of the patients who achieved social continence with at least 1-year followup 23 (60.9%) remained so with no further treatment. At 2-year followup 21 patients (42.8%) maintained social continence. The success rate was 27.3% for those who wore a penile clamp or condom catheter before treatment (3 of 11 patients), and only 21.4% for those who underwent transurethral incision of a bladder neck contracture (3 of 14). A median of 4 injection procedures and 20.0 ml. collagen were required to achieve social continence. CONCLUSIONS: Transurethral collagen injection therapy is a reasonable treatment option for post-prostatectomy incontinence in select patients in whom more conservative therapy has failed. However, patients who have required a penile clamp, experienced continuous leakage or undergone transurethral incision of a bladder neck contracture are unlikely to respond well to this treatment.

Fluid loss quantitation test in women with urinary incontinence: a test-retest analysis.

A modified perineal pad-weighing method for objective quantitation of fluid loss is presented. The bladder was filled by retrograde flow, a sequence of provocative maneuvers was performed under direct supervision, and fluid loss was determined by pad weights. An analysis of immediate test-retest correlation and variability was done in patients with either sphincteric incompetence alone (N = 46) or detrusor instability with or without concomitant sphincteric incompetence (N = 21). Test-retest correlations were high in both groups, suggesting that the method could be applied as an index of severity of urinary incontinence in women. Test-retest within-patient variability was considerable, and limits its usefulness in the analysis of treatment outcome.

A vaginal device (continence guard) in the management of urge incontinence in women.

The aim of the study was to assess the efficacy of a disposable vaginal device in the management of urge incontinence. A total of 38 women with urge incontinence and uninhibited bladder contractions during cystometry were included. They wore the device from morning to night. Before, and again after, using the device for 1 month the women were assessed by pelvic examination, uroflowmetry, postvoid residual urine, two 24-hour pad-tests, a 3-day voiding diary and vaginal and urine cultures. A questionnaire about the subjective effect and adverse events was completed. Thirty women (79%) completed the study. Two (6.7%) were subjectively cured when using the device, 15 (50%) were improved, and 13 (43.3%) experienced unchanged incontinence. The 24-hour pad-test leakage showed a statistically significant decrease (P=0.001) - in 11 women (36.7%) the decrease was more than 50%. The other urodynamic results were unchanged. A significant decrease in the number of daily micturitions was found in the group of responders (P=0.02). No vaginal infections were found; 4 women (13%) had uncomplicated urinary tract infection during the test-period. Subjective complaints were few, and 21 women (70%) wanted to continue the treatment with the device. The vaginal device constitutes a new option in the management of urge incontinence, with a subjective and objective cure/improvement rate of 56.7%. The device is easy to use and well accepted.

A randomized controlled trial comparing a modified Burch procedure and a suburethral sling: long-term follow-up.

The aim of this study was to compare the long-term results of a modified Burch procedure with a sling procedure for the treatment of stress incontinence with a low-pressure urethra. Thirty-six women with urodynamic stress incontinence, low-pressure urethra, urethral hypermobility and no significant pelvic organ prolapse were randomly assigned to undergo either a modified Burch procedure ( n=19) or a sling placement ( n=17). Cure of the stress incontinence (defined as a negative stress test and negative pad-weight test) was the primary long-term endpoint. Secondary endpoints included subjective cure of stress incontinence (defined as no incontinence episodes on a 1-week voiding diary) and voiding function studies. Comparisons of group means were performed with the Mann-Whitney U-test, pooled variance t-tests and separate variance t-tests. Proportions were compared with Fisher's exact test. A logistic regression analysis was performed to control for covariates that differed in our two groups despite randomization. Long-term follow-up (mean=72.6 months) was available for 82% (28/34) of the original study group. The objective cure rates for the Burch and sling groups were 84.6% and 100%, respectively ( P=0.17). Mean uroflowmetry rates for the Burch and sling groups were 7.38 and 6.8 ml/s, respectively ( P=0.58, 95%CI -2.5, 4.4). Mean postvoid residual volumes for both groups were 35 ml ( P=0.97, 95% CI -23.8, 65.9). Two sling patients (12%) required partial resection of their slings because of erosion. Both patients remained continent. In terms of voiding function and stress incontinence cure, there were no differences between groups undergoing modified Burch or sling procedures for treatment of urodynamic stress incontinence with low-pressure urethra.

Exercise and incontinence.

Three hundred twenty-six women filled out questionnaires to assess the relationship between exercise and incontinence. Two hundred ninety participants stated that they exercised regularly. Overall, 152 (47%) noted some degree of incontinence, which correlated positively with the number of vaginal deliveries (P less than .0005). Eighty-seven exercisers (30%) noted incontinence during at least one type of exercise. Incontinence exclusively during exercise was seen in only one woman. Exercises involving repetitive bouncing were associated with the highest incidence of incontinence. Seventeen incontinent exercisers (20%) stopped an exercise because of incontinence, whereas 16 (18%) changed the way a specific exercise was done and 48 (55%) wore a pad during exercise. Thirty-five percent had discussed their incontinence with a health care professional. These data suggest that incontinence during exercise is a common, although little known, problem. In addition to the behavioral adaptations which women initiate on their own, surgical and nonsurgical treatments may be of benefit.

Quantification of urine loss by weighing perineal pads. Observation on the exercise regimen.

Two variations on a test for quantifying urine loss in patients with urinary incontinence were compared. In the first series (Padtest 1), 335 patients underwent a 2-h pad weighing test. A fluid load of 1 litre was administered and followed 1 h later by six separate exercises, each lasting 10 min. One of six sanitary towels was worn during each exercise. Each pad was weighed before and after use to provide information about the severity of the incontinence. In the second series (Padtest 2), 104 patients were studied. The test took the same format but the exercises were rearranged in an attempt to provide information about the importance of the individual exercises. Hand washing was found to be a very provocative test both in women with unstable and those with stable bladders. The order in which the exercises were performed did not influence the overall identification of incontinence in the 2-h test period, and this supports the conclusion that the optimum length of the test is 2 h.

Comparison of pelvic floor muscle training, electromyography biofeedback, and neuromuscular electrical stimulation for bladder dysfunction in people with multiple sclerosis: a randomized pilot study.

AIM: Bladder dysfunction affects up to 90% of the multiple sclerosis (MS) population. Interventions such as Pelvic Floor Training and Advice (PFTA), Electromyography (EMG) Biofeedback, and Neuromuscular Electrical Stimulation (NMES) have received limited research attention within this population. This study aimed to determine the effectiveness of a combined programme of PFTA, EMG Biofeedback, and NMES for bladder dysfunction in MS. METHODS: Females (n = 30) who fulfilled strict inclusion/exclusion criteria were recruited. Outcome measures (weeks 0, 9, 16, and 24) included: 3-day Voiding Diary; 24 hr Pad-Test; Uroflowmetry; Pelvic Floor Muscle Assessment; Incontinence Impact Questionnaire (IIQ); Urogenital Distress Inventory (UDI); King's Health Questionnaire (KHQ), and the Multiple Sclerosis Quality of Life-54 Instrument (MSQoL-54). Following baseline (week 0) assessment, participants were randomly allocated, under double blind conditions, to one of the three groups: Group 1 (PFTA); Group 2 (PFTA and EMG Biofeedback); and Group 3 (PFTA, EMG Biofeedback, and NMES). Treatment was for 9 weeks. RESULTS: Baseline severity (measured by number of leaks and pad weight) showed some variation between groups, although not statistically significant (P > 0.05); with the caveat that this baseline imbalance makes interpretation difficult, a picture emerges that at week 9, Group 3 demonstrated superior benefit as measured by the number of leaks and pad test than Group 2, with Group 1 showing less improvement when compared to week 0; this was statistically significant between Groups 1 and 3 for number of leaks (P = 0.014) and pad tests (P = 0.001), and Groups 1 and 2 for pad tests (P = 0.001). A similar pattern was evident for all other outcome measures. CONCLUSION: Results suggest that these treatments, used in combination, may reduce urinary symptoms in MS. Further research will establish the effectiveness of these interventions.

Urinary incontinence following treatment of localized prostate cancer.

BACKGROUND: Urinary incontinence (UI) following treatment for localized prostate cancer is a significant adverse consequence most commonly seen after radical prostatectomy. UI can significantly impair the quality of life of patients who can otherwise expect a long survival. METHODS: The authors review past and present literature on UI following treatment for localized prostate cancer. Special focus is placed on the rate of UI following different modes of therapy, the effect of posttreatment UI on patients' quality of life, and the success of different methods used to treat the incontinence. RESULTS: Postprostatectomy UI has been reported in 25%-70% of cases, but few patients report being significantly bothered by the symptom. Postradiation adverse effects are mainly acute inflammatory, while late complications are rare but usually more serious. Comparative studies estimate UI following prostatectomy to be two times more common than following radiation, and surgical patients are three times more likely to continue to use pads. Watchful waiting carries a risk of incontinence related to prostate tumor progression. Several interventions can improve UI. CONCLUSIONS: UI is the most common adverse consequence from treatment for localized prostate cancer. All of the possible treatment modalities carry some risk of UI. Providing accurate information to patients allows them to make informed decisions regarding treatment and can improve the quality of life in the posttreatment period.

The Incontinence Impact Questionnaire and the Urogenital Distress Inventory: a revisit of their validity in women without a urodynamic diagnosis.

OBJECTIVES: We sought to assess validity of the Incontinence Impact Questionnaire (IIQ) and the Urogenital Distress Inventory (UDI) (long and short forms) in incontinent women previously urodynamically undiagnosed. STUDY DESIGN: Post hoc analysis of responses to the IIQ and UDI questionnaires were obtained from a trial on a urethral device in community-dwelling incontinent women. Internal consistency and validity were evaluated against the 1-hour pad test. RESULTS: Internal consistency (Cronbach's alpha) for the long forms was high for the IIQ and moderately high for the UDI, good for the IIQ-short, but poor for the UDI-short. Correlations with 1h pad test were low and non-significant for both versions. Correlation of the short with the long forms was high. CONCLUSION: In the community-dwelling population, without a urodynamic diagnosis, neither long nor short versions of the questionnaires correlate with the severity of the urinary incontinence as shown by the pad test. The validity of the current questionnaires in women without urodynamic diagnosis is questionable.

Effectiveness of early pelvic floor rehabilitation treatment for post-prostatectomy incontinence.

PURPOSE: Urinary incontinence after radical prostatectomy is a significant clinical problem. In this prospective study we investigate the effectiveness of early pelvic floor muscle training (PFMT) on a large population, that had undergone radical retropubic prostatectomy (RRP) at our department. METHODS: 300 consecutive patients who had undergone RRP for clinically confined prostate cancer were randomized in two groups after catheter removal. One group of 150 patients took part in a structured PFMT program. This began before discharge and consisted of Kegel exercises. The remaining 150 patients constituted the control group, they were not formally instructed in PFMT. Incontinence was assessed objectively using the 1 hour and 24 hour pad test, as well as with the ICS-Male questionnaire. All patients who were incontinent after 6 months underwent urodynamic evaluation. RESULTS: In the treated group, 19% (29 patients) achieved continence after 1 month, and 94.6% (146 patients) after 6 months. In the control group 8% (12 patients) achieved continence after 1 month, and 65% (97 patients) after 6 months (p<0.001). Patient age did not correlate with continence in the control group (p>0.05), although a significant correlation was revealed within the treated group (p<0.01). Overall, 93.3% of the total population achieved continence after one year. CONCLUSIONS: After RRP an early supportive rehabilitation program like PFMT significantly reduces continence recovery time.

Collagen injection for the treatment of incontinence after cystectomy and orthotopic neobladder reconstruction in women.

PURPOSE: We determine the clinical efficacy of endoscopically injected collagen for the treatment of new onset urinary incontinence in women following cystectomy and orthotopic neobladder. MATERIALS AND METHODS: Three women 58 to 74 years old underwent transurethral collagen injection for stress urinary incontinence following cystectomy and orthotopic neobladder. Before cystectomy 2 women denied having any stress urinary incontinence while 1 complained of mild incontinence. Onset of incontinence following cystectomy and neobladder formation ranged from 8 months to 3 years, and average pad use ranged from 3 to 5 per 24-hour period. All patients underwent video urodynamic evaluation before collagen injection. Neobladder capacity was 180 to 400 cc and Valsalva leak point pressures ranged from 30 to 60 cm. water. RESULTS: A total of 6 injections were given, including 3 injections in 1 patient, 2 in 1 and 1 in 1. All 3 women had significant improvement or became dry with initial injection but required repeat injections to maintain improved continence status. At 7 to 8 months after the last injection 1 woman was dry, 1 used 1 or no pad daily and 1 reported no durable change in stress urinary incontinence. CONCLUSIONS: Collagen injection appears to be a successful, minimally invasive treatment for new onset stress urinary incontinence following cystectomy and orthotopic neobladder in women.

The further development of the active urine collection device: a novel continence management system.

Continence difficulties affect the lives of a substantial minority of the population. Women are far more likely than men to be affected by urinary incontinence but the range of management options for them is limited. There has been considerable interest in developing an external urine collection system for women but without success to date. This paper describes the development and preliminary clinical testing of an active urine collection device (AUCD), which could provide a solution for sufferers. The device uses stored vacuum, protected by a high bubble point filter, to remove urine as quickly as it is produced. This allows a small battery-operated pump to provide the required vacuum, enabling the device to be portable. Two different types of non-invasive patient/device interface were developed, and tested by volunteers: urinal and small pad. The slimline urinal was popular with users although liquid noise was a problem. The pad interface was successful on occasions but further work is necessary to produce a reliable pad. This study has successfully demonstrated that a prototype AUCD liquid handling system can remove urine at clinically relevant flowrates. While further development is required, volunteer tests have shown that the AUCD could be a useful advance in continence management.

Long-term results after antegrade collagen injection for stress urinary incontinence following radical retropubic prostatectomy.

OBJECTIVE: To evaluate the long-term success of antegrade collagen injection in men with stress urinary incontinence after radical prostatectomy. METHODS: Between October 1994 and January 1996, 20 patients underwent antegrade collagen injection for stress urinary incontinence caused by radical prostatectomy. Evaluation by pad test, urodynamics, and subjective scores was performed before and after injection. RESULTS: At a mean follow-up of 28 months, 10% of the patients were cured and 35% were improved. All patients received a single treatment (mean total volume of collagen injected 14.5 mL). In 11 patients without long-term improvement, 2 had undergone irradiation previously and 7 had failed retrograde collagen injections. Two patients with vesical neck contracture were successfully treated. Preoperative incontinence severity and stress leak point pressure did not correlate with failure. CONCLUSIONS: A 45% cured or improved rate at long-term follow-up is possible in men with stress incontinence after radical prostatectomy using a single antegrade collagen injection. Although antegrade delivery of collagen for stress incontinence minimized short-term, technique-related failures, for a substantial number of patients therapy had failed at long-term follow-up.

A novel surgical technique for implanting a new electrostimulation system for treating female overactive bladder: a preliminary report.

OBJECTIVE: To assess the results of peripheral electrostimulation of pelvic floor muscles in patients with overactive bladder (OAB) symptoms, and to describe a novel surgical technique for inserting a specially designed implantable electrostimulator which can deliver different forms of muscle stimulation through a para-urethral electrode. PATIENTS AND METHODS: The study included seven women with OAB (mean age 59 years) who had frequency (including nocturia), urgency and urge incontinence for > or = 1 year, and in whom conventional treatment failed. The antepubic technique was used to implant the electrostimulator and a para-urethral electrode. The patients' urinary symptoms and quality of life (King's College Hospital incontinence questionnaire) were compared before and after surgery, and possible complications monitored. RESULTS: The mean (range) follow-up was 14.5 (13-17) months in six and 10 months in the seventh patient (stimulator removed because of infection). The mean (range) frequency of 15 (13-23) voids/24 h before surgery decreased to 9 voids/24 h (i.e. by 40%) afterward. All patients had leakage episodes because of urgency (4-15 times/day) before surgery, which ceased in five afterward; these patients used no further pads. In the remaining two patients urgency incontinence continued after surgery, but with significantly fewer leakage episodes, from 15 and 12 per day before to 6.7 and 4 afterward, respectively. The mean degree of urgency (graded 0-3) decreased from 2 to 1.4 after surgery, and quality of life improved significantly. Urodynamic studies showed a greater mean maximum detrusor capacity, from 135 mL before to 189 mL after implanting the stimulator. CONCLUSIONS: The good results (over a follow-up of 1 year) in patients with OAB symptoms treated by the present electrostimulator should encourage further clinical studies in such patients. A trial to evaluate the efficacy of pelvic floor muscle electrostimulation in a broad spectrum of diseases of the lower urinary tract causing symptoms similar to OAB has been started.

Outcomes with an alternative anastomotic technique after radical retropubic prostatectomy: 10-year experience.

OBJECTIVES: To review 10-year outcomes of an alternative vesicourethral anastomotic technique performed after radical retropubic prostatectomy (RRP). METHODS: With institutional review board approval, 307 consecutive RRPs performed by one surgeon (mean patient age, 63.5 years; range, 35 to 77 years) from November 1994 to December 2004 with an alternative anastomosis were reviewed. Cox proportional hazard models with forward selection were used to investigate associations with outcomes and operative parameters. RESULTS: Mean estimated blood loss (EBL) was 550 mL. Sixty-three patients (20.5%) required blood transfusion. Mean anastomotic time ranged from 8 to 22 minutes (median, 11 minutes). Nine patients (2.9%) required surgical drain for more than 2 days. A total of 246 patients were available for at least 1-year continence follow-up (mean, 51 months). Of these, 160 patients (65.0%) never leaked or required a pad at point of last follow-up; 25 patients (10.2%) required 1 non-insurance pad or more per day. Only 3 patients (1.2%) have had incontinence interventions (one artificial sphincter and two collagen injections). Operative parameters statistically associated with wearing 1 pad per day or more were EBL (P = 0.035) and time to continence (P <0.001). Forty-three patients (17.5%) required stricture dilation, with a mean time to intervention of 6 months (range, 1 to 33 months). No patient required incision of bladder neck contracture. The only statistically associated factors with stricture formation were increased age and increased EBL. CONCLUSIONS: The alternative anastomotic technique is efficient and provides proper urethral alignment with a minimal rate of prolonged urinary extravasation. Long-term urinary continence is excellent, and stricture rates are acceptable compared with other anastomotic techniques.
