Dry mouth with conventional and controlled-release oxybutynin in urinary incontinence

Objective To compare the efficacy and safety of controlled-release oxybutynin with conventional, immediate-release oxybutynin and determine rates of dry mouth. Methods Patients (n = 226) who were known to be responsive to anticholinergic therapy and who had seven or more urge incontinence episodes per week were randomized to receive controlled-release oxybutynin or immediate-release oxybutynin. After an initial placebo run-in period, dosing in each began at 5 mg per day and increased weekly by 5 mg per day to a maximum of 20 mg per day or when a balance between improvement of incontinence symptoms and tolerability of side effects was achieved. Rates of urge incontinence and dry mouth were compared. Post hoc Kaplan-Meier survival analysis was used to describe elimination of incontinence episodes by dose and to analyze dry mouth risk by dose. Results Reductions in urge urinary incontinence episodes from baseline to the end of treatment were 18.6 to 2.9 per week (83% mean decrease) and 19.8 to 4.4 per week (76% mean decrease) in the controlled- and immediate-release oxybutynin groups (P = .36), respectively. At equal doses, comparable proportions of patients in both groups reported the absence of urge incontinence (P = .85). The incidence of dry mouth increased with dose in both groups, but there was no difference in dry mouth rates between the groups: 47.7% and 59.1% for the controlled- and immediate-release oxybutynin (P = .09), respectively. However, Kaplan-Meier analysis to examine first report of dry mouth at a given dose revealed that a significantly lower proportion of patients taking controlled-release oxybutynin had moderate to severe dry mouth (P = .007) or any dry mouth (P = .003) compared with those taking immediate-release oxybutynin. Conclusion At the same daily dose, controlled- and immediate-release oxybutynin demonstrated comparable efficacy in reduction of urge incontinence episodes. The incidence of dry mouth was dose dependent but equal in both groups; first report of moderate to severe dry mouth was significantly lower in the controlled-release group.

Urogenital prolapse and atrophy at menopause: a prevalence study.

Abstract: For 285 subjects referred to a menopause clinic data were prospectively collected on the time elapsed since the onset of menopause (menopausal age), sexual activity, dyspareunia, smoking, chronic cough and constipation. Prolapse and atrophy were sought on examination. FSH assay confirmed menopausal status. We found an anterior wall prolapse in 51% of the subjects, of which 6% were protruding beyond the introitus. Posterior wall prolapse was present in 27% and apical prolapse in 20%; none was protruding beyond the introitus. No trend was noted between prolapse and menopausal age. Atrophy was evident in 34% of the women, and this was related to menopausal age (P<0.001). Forty per cent of the sexually active women admitted to dyspareunia, of which 2/3 were superficial. This correlated with advancing menopausal age (P<0.02). In conclusion, genital prolapse was frequent in the population of postmenopausal women, predominantly cystocele, but the prevalence did not correlate with menopausal age.

A Systematic Review of Estrogens for Recurrent Urinary Tract Infections: Third Report of the Hormones and Urogenital Therapy (HUT) Committee

Abstract: Our objective was to apply a meta-analysis to the available data to evaluate the effect of estrogen supplementation in the prevention of recurrent urinary tract infections in postmenopausal women. The literature review incorporated articles based on a search of Excerpta Medica, Medline, Science Citation Index and a manual search of commonly read journals in the fields of urology, gynecology, gerontology and primary healthcare, from January 1969 to December 1998. The search was not limited to English-language publications. Inclusion criteria were peer-reviewed articles containing original data with a primary outcome of symptomatic urinary tract infections and an estrogen-treated group. Articles were categorized into randomized controlled trials, case–control studies and self-controlled series. Of the articles reviewed, five were randomized controlled trials, two were case–control studies and three were self-control series. Meta-analysis of data from 334 subjects revealed a significant benefit from estrogen over placebo (odds ratio = 2.51, 95% confidence interval = 1.48–4.25). The most convincing results were obtained using the vaginal route of administration. A variety of different estrogen preparations have been employed in the few published reports, making comparison of the data difficult. However, vaginal administration seems to be effective in the prevention of recurrent urinary tract infections in postmenopausal women.

Evaluation of the home pad test in the investigation of female urinary incontinence

Objective To evaluate the use of the home pad test in the management of patients with urinary dysfunction with reference to feasibility, normal data, reproducibility, compliance and accuracy when compared to video urodynamics.

Internal urinary sphincter in maintenance of female continence.

The integrity of the bladder neck was assessed in 98 continent women. Radiological and physiological evidence showed that half of these women had an incompetent bladder neck, but they were still continent. These data devalue the urodynamic finding of an incompetent bladder neck as an indication for surgery for incontinence and question the physiological importance of the internal sphincter.

Predictive value of clinical evaluation of stress urinary incontinence: a summary of the published literature.

Abstract: Our objective was to evaluate the symptom and sign of stress incontinence in predicting the presence of urodynamically diagnosed genuine stress incontinence (GSI). The study was a computation of the sensitivity and predictive values from the published literature (1975–1998), evaluating the history and/or physical examination for the diagnosis of GSI, with calculation of efficacy variables. Results show that the isolated symptom of stress incontinence has a positive predictive value (PPV) of 56% for the diagnosis of pure GSI and 79% for GSI with additional abnormalities. The PPV of stress incontinence in association with other symptoms is 77% in detecting GSI (with or without additional abnormalities). A positive cough stress test has a PPV of 55% for detecting pure GSI and 91% for the mixed condition (GSI plus additional diagnosis). When isolated, the symptom or the sign of stress incontinence is a poor predictor of GSI. In combination, the prediction may be more promising.

A new external urethral occlusive device for female urinary incontinence

Objective Determine the efficacy of a new external antiincontinence urethral device. Methods A before-after 1 month trial, open longitudinal study of 155 women complaining of urinary incontinence recruited from a referral urogynecology practice and local media advertising was performed. Primary outcomes included assessing the efficacy of the device using visual analogue scales, quality-of-life questionnaires, 1and 48hour standardized pad tests, and voiding diary. Secondary outcomes consisted of the evaluation of the adverse effects and the clinical profile of patients willing to use the device after study completion. Results Ninety-six (62%) of 155 women enrolled completed the study. Scores on the visual analogue scales improved for the symptoms of stress incontinence, urgency, and urge incontinence (P < .001). The score for irritation/discomfort increased (P < .001). Data from diaries showed that 38 (44%, n = 86) patients were dry. Of 454 recorded patient-days, 325 (72%) were dry days. On pad testing, incontinence was cured in 49% (1-hour pad test, n = 59, P < .001) and 44% (48-hour pad test, n = 32, P < .001) of patients. Quality-of-life scores were significantly improved in 48% (n = 96, Incontinence Impact Questionnaire, P < .001) and 32% (n = 96, Urogenital Distress Inventory, P < .001) of patients. There was no increase in bacteriuria. After study completion, 61 (39%) women chose to continue using the device, but this was not predictable from baseline data. Conclusion Use of this device resulted in a significant reduction in incontinence and improvement in quality-oflife issues with minimal adverse events in the majority of women. This new anti-incontinence device could become a useful addition to the armamentarium of nonsurgical options.

Videourodynamic diagnosis of occult genuine stress incontinence in patients with anterior vaginal wall relaxation

Objective: To (1) utilize videourodynamics, the gold standard, to assess the prevalence of occult genuine stress incontinence (GSI) among preoperative patients with symptomatic anterior vaginal wall relaxation and (2) identify urodynamic discriminators that might help predict occult GSI. Methods: In this prospective study, videourodynamic evaluation was performed on 48 consecutive patients presenting for preoperative urodynamic evaluation of anterior vaginal wall prolapse. Patients with occult GSI were identified by urodynamic testing with and without Gehrung pessary support of the bladder base during stress maneuvers. Variables from the history, physical examination, and videourodynamics were then analyzed. Results: The overall incidence of occult GSI was 25% (22.7% in the pelvic organ prolapse [POP] group and 26.9% in the POP-UI group). Patients with occult GSI were nolt identifiable on history but did have a higher incidence of late first sensation, open bladder neck at rest, and hypermobility on imaging with videourodynamics. Conclusion: This study suggests that one quarter of women presenting with anterior wall relaxation with or without incontinence symptoms have occult GSI. Given this high prevalence, preoperative evaluation with urodynamics, possibly videourodynamics, utilizing bladder base support is justified if the data are substantiated in a larger, definitive study. Patients with a late first sensation, open bladder neck, and hypermobility may have a higher incidence of occult GSI.

Obstetric outcome of Bangladeshi women in East London

Objective To study the obstetric outcome of women of Bangladeshi origin in comparison with the white Caucasian population in East London.

Bacteriuria in pregnancy: a comparison of Bangladeshi and Caucasian women.

During a 5-year period all urine culture results from pregnant Caucasian and Bangladeshi women booked for confinement at the Royal London Hospital, London, UK, were reviewed to determine race-specific rates of bacteriuria. The results showed that the overall prevalence of bacteriuria in the Caucasian group was 6.3% compared to 2.0% for the Bangladeshi women. Caucasian women were found to be at significantly greater risk across all pregnancy outcome and history categories, with the greatest risk observed in grand multiparous women (RR: 4.7, 95% CI: 2.8–8.3). Pregnancies that resulted in preterm delivery showed a strong association of bacteriuria in Caucasian women which was not seen in the Bangladeshi women (RR: 4.4, 95% CI: 2.0–8.7). The data suggest that Caucasian women have a significantly higher prevalence of bacteriuria in pregnancy than their Bangladeshi neighbors. Differences in hygiene practices and clothing may explain the observed differences in the bacteriuria rates.
