A rapid systematic review of postpartum bladder care guidelines and recommendations in the context of the COVID-19 pandemic.

New pathways for the management of postpartum voiding dysfunction and postpartum urinary retention should be considered to shorten hospital stays and promote early discharge during the COVID-19 pandemic. This rapid systematic review aimed to identify relevant national and international guidelines, and summarise available recommendations on postpartum bladder care that are relevant to women's care and management at the time of the pandemic. We searched Medline, Embase and Cochrane from inception till September 2021. Hand-searching of national and international specialist societies' websites was performed. We identified one international technical consultation, one international society's report of recommendations and two national guidelines. Guidelines stated that postnatal women should not be left more than 6 hours without voiding and assessed for postpartum urinary retention. As the cut-off of 150 ml for the diagnosis of significant postvoid residual volume is commonly used with no reported adverse outcomes, it could be beneficial to adopt this instead of 100 ml as further unnecessary interventions can be avoided. Such changes can reduce the number of women staying in the hospital. Clean intermittent self-catheterisation for the management of postpartum urinary retention could be considered as an option during the COVID-19 pandemic aiming to shorten hospital stays and avoid further attendances. Optimised bladder care has become more relevant during the coronavirus pandemic by striving towards self-care, community-based and remote care. We propose consideration of intermittent self-catheterisation in cases of postpartum urinary retention enabling self-care and avoidance of hospital visits.

Does the vaginal wall become thinner as prolapse grade increases?

INTRODUCTION AND HYPOTHESIS: The pathophysiology of prolapse is not well understood. However, two main theories predominate: either the fibromuscular layer of the vagina develops a defect/tears away from its supports, or its tissues are stretched and attenuated. The aim of this study was to assess how vaginal wall thickness (VWT) is related to vaginal prolapse. METHODS: The study group comprised 243 women with symptomatic prolapse recruited from the Outpatient Department of a tertiary referral centre for urogynaecology. A history was taken and women were examined to determine their POP-Q score. Using a previously validated technique, ultrasonography was used to measure the mean VWT at three anatomical sites on the anterior and posterior walls. Scores were then compared using t tests, the Kruskal-Wallis test and the Friedman test. RESULTS: The mean age of the patients was 59.7 years (SD 12.0 years range 38 - 84 years). For each measurement VWT reduced as prolapse grade increased until the prolapse extended beyond the hymen. Women with grade 3 prolapse had a significantly higher mean VWT than women with grade 1 or 2 contained prolapse. Menopause status did not have a significant effect on the VWT. CONCLUSIONS: VWT is lower in women with vaginal prolapse until the prolapse extends beyond the hymen and then VWT is thicker and comparable with women without prolapse. This may be explained by changes in the vaginal tissue including reduction of collagen, elastin and smooth muscle, as well as fibrosis in exposed tissues, rather than by defects in the vagina.

Changes in detrusor muscle oxygenation during detrusor overactivity contractions.

OBJECTIVE: To investigate changes in the oxygenated and deoxygenated haemoglobin (Hb) of the bladder wall during voluntary and involuntary detrusor contractions. STUDY DESIGN: Women with lower urinary tract symptoms were recruited from a urodynamics clinic. Near infra-red spectroscopy, a non-invasive optical technique which monitors changes in tissue oxygenation, was used to measure oxygenated and deoxygenated haemoglobin simultaneously while the women underwent urodynamics. All data were compared using paired sample t-test. RESULTS: Fifty-five women with a mean age of 52 years were enrolled into the study. In the 23 women with detrusor overactivity (15 with isolated detrusor overactivity and 8 with mixed urinary incontinence) there was a statistically significant rise in deoxygenated Hb during involuntary detrusor contractions at maximum detrusor pressure compared to the start of filling (p=0.02). There was no statistically significant change between Hb parameters measured at the start of the filling phase and those measured during voluntary detrusor contraction at pdetQmax (detrusor pressure at maximum flow rate). The mean detrusor pressure measured during voiding, however, was significantly higher than the maximum pressure during involuntary detrusor contractions (p=0.03). CONCLUSION: There is a significant rise in the deoxygenated Hb in the detrusor muscle during detrusor overactivity, which is not seen during voiding even when the pdetQmax was higher than the peak detrusor pressure during involuntary contractions. These interesting changes in detrusor muscle oxygenation during involuntary detrusor contraction need to be explored further to assess if deoxygenation plays a role in the pathogenesis of detrusor overactivity.

Women's perspective of botulinum toxin treatment for overactive bladder symptoms.

INTRODUCTION AND HYPOTHESIS: This study aimed to evaluate the women's' views and expectations about outcomes and complications of botulinum toxin treatment for overactive bladder (OAB) symptoms. METHODS: Consecutive women with OAB symptoms and detrusor overactivity were requested to fill out a multiple choice questionnaire to assess whether they would consider botulinum and what outcomes as well as complications they would find acceptable to undergo this treatment. RESULTS: Two hundred sixty-one women, mean age of 58 (range, 38-78) years, were studied. Two hundred twenty-four were treatment-naive women (group A), while 37 were no responders to anticholinergics (group B). Only 49.6% of women in group A and 54% in group B would accept botulinum toxin. No significant differences were found between treatment-naive women and non-responders to anticholinergics (p > 0.05). CONCLUSIONS: Acceptance of botulinum toxin treatment involves a complex interaction of efficacy and possible complications. The balance of these factors changes the acceptability of the treatment.

Ultrasound measurement of vaginal wall thickness: a novel and reliable technique.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to validate a technique to measure the vaginal wall thickness (VWT) using two-dimensional ultrasound. METHODS: Women were scanned by two independent operators and by the same operator at two separate visits at the level of the bladder neck, the apex of the bladder, the anterior fornix, the anorectal junction, rectum and posterior fornix. Fresh female cadavers were scanned and ultrasound thickness of the vagina was compared to histological thickness. RESULTS: Bland Altman analysis revealed a low mean difference between operators and between visits by the same operator. The 95% confidence intervals as a percentage of the mean vaginal wall thickness ranged between 2.8% and 7.4%. There was a low percentage difference between ultrasound and histological vaginal wall thickness. CONCLUSION: Ultrasound vaginal wall thickness demonstrated good intra- and interoperator reliability, as well as consistency with histological measurement. It is a valid technique.

Transvaginal ultrasound measurement of bladder wall thickness: a more reliable approach than transperineal and transabdominal approaches.

OBJECTIVES To validate transperineal, transabdominal and transvaginal ultrasound (US) techniques to measure bladder wall thickness (BWT). SUBJECTS AND METHODS Women underwent US measurement of BWT at three different anatomical sites: anterior wall, dome and trigone of the bladder by two 'blinded' operators using transabdominal, transperineal and transvaginal approaches at separate visits and by a single operator using transabdominal and transperineal techniques. Bland-Altman analysis was used to determine interobserver reliability for all three techniques and intraobserver reliability for transabdominal and transperineal methods. RESULTS In all, 25 women were scanned. The transperineal US had a high interobserver mean difference when measuring the anterior BWT (-0.34) and a high intraobserver mean difference when measuring the anterior (0.54) and dome BWT (0.33). Transabdominal US had a high interobserver mean difference for all measurements of BWT, and a high intraobserver mean difference when measuring the trigonal thickness (0.56). Transvaginal US had a consistent interobserver mean difference for all three measurements. The transperineal and transabominal approaches had the widest intraobserver and interobserver 95% confidence intervals of the mean difference when compared with the transvaginal approach. CONCLUSIONS Transabdominal and transperineal US for measuring BWT did not have good intraobserver and interobserver reliability for measurement of the three anatomical sites to determine mean BWT. Transvaginal US had good interobserver reliability, thus mean BWT is best measured using the transvaginal approach.

Validity of the Rome III Criteria in assessing constipation in women.

INTRODUCTION AND HYPOTHESIS: A study was conducted to validate a constipation questionnaire based on the Rome III criteria. METHODS: Women attending outpatient clinics completed a constipation questionnaire based on the Rome III Criteria. The internal reliability, the test-retest as well as the content and construct validity of the questionnaire were evaluated. RESULTS: Two hundred one women were studied. Of the women, 28% (56/201) reported constipation but only 14% of these (8/56) could be defined as constipated accordingly to the Rome III Criteria. Nine percent of women (13/145) who did not report constipation were classified as constipated accordingly to the Rome III Criteria. The questionnaire had good reliability (Cronbach's alpha of 0.85 and ICC of 0.85). However, the questionnaire did not have significant construct validity with patients' self-report of constipation, stool frequency and stool form (Pearson chi-square P > 0.05). CONCLUSIONS: The Rome III Criteria questionnaire is a reliable and reproducible tool but does not appear to be a valid instrument in diagnosing constipation.

A persistent bladder erosion with ureteric involvement following mesh augmented repair of cystocele.

We present a case of a 57-year-old woman who sustained bladder erosion with extension to the left ureter after a mesh-augmented recurrent cystocele repair. The persistence of the eroding mesh eventually necessitated a partial cystectomy and distal left ureterectomy, using a Boari flap technique.

Is the beneficial effect of antimuscarinics related to motor or sensory changes in the bladder?

INTRODUCTION AND HYPOTHESIS: The aim of the study was to assess the sensory and motor effects of antimuscarinic treatment on the bladder in women with overactive bladder, detrusor overactivity demonstrated on urodynamics and a mean bladder wall thickness (BWT) greater than 5 mm. METHODS: Fifty-eight women underwent treatment with antimuscarinics in 12 weeks. Before treatment and at 1, 2, 6 and 12 weeks of treatment, women completed the patient perception of bladder condition (PPBC) single-item global questionnaire, indicated the severity of their urgency on a visual analogue scale (VAS) and underwent transvaginal ultrasound to determine mean bladder wall thickness (BWT). RESULTS: PPBC and VAS scores for urgency declined throughout the treatment course whereas mean BWT declined during the first 6 weeks of treatment and then reached a plateau after falling to below 5 mm. CONCLUSION: The mechanism of action of antimuscarinics appears to be a complex interaction of sensory and motor components.

Reliability and normal ranges for the Patient's Perception of Intensity of Urgency Scale in asymptomatic women.

STUDY TYPE: Symptom prevalence (prospective cohort). LEVEL OF EVIDENCE: 1b. OBJECTIVE: To measure the test-retest reliability of a 7-day bladder diary incorporating the Patient's Perception of Intensity of Urgency Scale (PPIUS), and to establish the normal values of the scale in a population of asymptomatic women. SUBJECTS AND METHODS: Women volunteers, aged > or =18 years, were screened with the International Consultation on Incontinence Modular Questionnaire - Female Lower Urinary Tract Symptoms Long Form, to exclude those with bothersome lower urinary tract symptoms. Participants completed two separate 7-day bladder diaries with a 1-week interval between. Reliability was assessed using intraclass correlation, Spearman's correlation, and Student's t-test. RESULTS: Forty volunteers were recruited. Most (67.5%) reported no urgency episodes. Convenience voids accounted for 26.8% of all voids. There was a significant positive effect of age (r = 0.34, P = 0.034) on urgency episodes, but no effect on mean urge scores (r = -0.03, P = 0.843). The reliability of assessment of frequency (0.86), nocturia (0.84), and the mean urge scores (0.85), were better than the reliability of assessment of urgency episodes (0.56), which occurred infrequently. The 95th centile for daily urinary frequency was 7.27 and for weekly urgency episodes was 2.00. CONCLUSION: The PPIUS is a reliable tool for assessing urinary urge sensation in women. Inclusion of this measure in bladder diaries does not compromise the recording of other variables.

Is ultrasound estimation of bladder weight a useful tool in the assessment of patients with lower urinary tract symptoms?

INTRODUCTION AND HYPOTHESIS: The aim of this study was to assess the relationship between ultrasound estimation of bladder weight (UEBW), symptoms and urodynamic diagnosis. METHODS: Women with lower urinary tract symptoms underwent urodynamics studies and measurement of UEBW at a fixed bladder volume. RESULTS: Women with overactive bladder symptoms had a median UEBW of 48.3 g (95% CI 44-52), with stress urinary incontinence a median UEBW of 35.1 g (95% CI 30-41) and with mixed urinary incontinence a median UEBW of 40.0 g (95% CI 37-43) (p<0.001). Women with detrusor overactivity had a median UEBW of 48.0 g (95% CI 46-51), with urodynamic stress incontinence a median UEBW of 30 g (95% CI 29-31) and detrusor overactivity and urodynamic stress incontinence a median UEBW of 37.3 g (95% CI 33-41) (p<0.001). CONCLUSIONS: UEBW is higher in women with overactive bladder and detrusor overactivity. UEBW may be a useful tool in women with lower urinary tract symptoms.

Urogynaecological problems in pregnancy and postpartum sequelae.

PURPOSE OF REVIEW: Women in pregnancy can experience lower urinary tract symptoms which are related to the pregnancy and delivery and iatrogenic, and related to use of epidural anaesthesia and urethral catheters. This article assesses the controversial relationship between pregnancy and delivery and the development of urinary incontinence and pelvic organ prolapse. RECENT FINDINGS: Lower urinary tract symptoms are common in pregnancy and they peak in the third trimester. If women have lower urinary tract symptoms prior to pregnancy, they are more likely to persist after delivery. Vaginal delivery is the factor most strongly associated with stress urinary incontinence after delivery and elective caesarean section may be protective. Vaginal childbirth causes levator ani injury and increase in levator hiatus size, and these persist following vaginal delivery. Women with levator ani injuries may be twice as likely to develop uterovaginal prolapse. Voiding difficulties are more likely to occur after a traditional epidural than a low dose or combined spinal epidural. SUMMARY: There is radiological evidence supporting pelvic floor injury following vaginal childbirth and epidemiological evidence for the relationship between vaginal delivery and urinary incontinence and pelvic organ prolapse. Rigorous long-term studies are needed to identify the direct relationship between these two phenomena.

Should we explain lower urinary tract symptoms to patients?

AIM: The aim of our study was to evaluate the understanding of lower urinary tract symptom (LUTS) terminology used by patients. MATERIALS AND METHODS: Women attending urodynamic clinics in United Kingdom, Australia, and Italy were asked to complete a questionnaire testing the women's understanding of stress urinary incontinence, urge urinary incontinence, frequency, urgency, nocturia, and hesitancy. Five possible explanations for the meaning of each symptom were given. RESULTS: A total of 138 consecutive women were prospectively recruited. The terms of daytime frequency, nocturia, urgency, urge urinary incontinence, stress urinary incontinence, and hesitancy were defined correctly, according to the International Continence Society terminology, only by 33% (45/138), 44% (61/138), 46% (64/138), 39% (54/138), 37% (51/138), and 41% (57/138) of women, respectively. Over 20% of women were unsure about the meaning of each symptom. We did not find any statistical difference between the three groups in determining the correct definition (P = 0.5). CONCLUSIONS: Our findings showed that most women do not know the correct meaning of LUTS terminology currently used by physicians.
