Urodynamic and questionnaire findings in urinary incontinent women with and without diabetes. Data from a health study.

INTRODUCTION AND HYPOTHESIS: Our aim was to compare urodynamic findings in urinary incontinent (UI) women with and without diabetes. METHODS: In the extensive Lolland-Falster Health Study, women with lower urinary tract symptoms were offered urodynamic testing. After excluding 6 women with incomplete urodynamic testing and 88 women without UI, our analysis ended up including 417 women (31 with and 386 without diabetes). Student's t-test and chi-squared test were used to compare differences of urodynamic findings. Urodynamic testing consisted of a 2-day bladder diary, post-void residual urine volume, filling cystometry, pressure-flow study, cough stress test, and uroflowmetry. Three experienced physicians in urogynecology evaluated all urodynamic findings leading to an overall conclusion of the test results. RESULTS: Self-reported data showed that compared to incontinent women without diabetes, incontinent women with diabetes had more frequent leakage, a larger amount of leakage, and a higher ICIQ score. A positive ICS Uniform cough stress test was more prevalent in women with diabetes. There were no significant differences in other urodynamic findings or overall conclusion between the two groups. Controlling for age and BMI did not affect our findings. CONCLUSIONS: Women with diabetes complained more about UI, had a higher ICIQ score, and had a positive ICS Uniform cough stress test more often than women without diabetes. Based on these findings, we recommend to include the history of urinary incontinence in the care of women with diabetes. This sample consists of women from a comprehensive health study with different severity of UI. Therefore, it can serve as a reference cohort for future studies.

Reoperation for pelvic organ prolapse: a Danish cohort study with 15-20 years' follow-up.

INTRODUCTION AND HYPOTHESIS: The objectives were to determine the reoperation rate of primary pelvic organ prolapse (POP) surgery, to describe the age distribution of the women at primary surgery for those undergoing a reoperation, and to describe the incidence of second and third reoperations. METHODS: We carried out a population-based registry study of Danish women above the age of 18 years when undergoing primary surgery for POP during the period 1996-2000. Data were retrieved from the Danish National Patient Register. All women were followed until one of the following events occurred: reoperation for POP, death, emigration, or end of follow-up period. Reoperation was defined as "repeated surgery in same compartment". The cumulative incidence rate of reoperation was divided into three compartments (anterior, apical, and posterior) and was calculated using Kaplan-Meier plots. RESULTS: A total of 18,382 procedures were performed on 11,805 women. After 20 years' follow-up, the cumulated incidence rate of reoperation for POP in the anterior, apical, and posterior compartments was 12.4%, 7.9%, and 12.1% respectively. The overall rate of reoperation was 11.5%. Of women aged between 18 and 49 years of age at primary surgery, 26.9% had a reoperation, whereas in women between 50 and 90+ years of age at primary surgery, only 10.1% had a reoperation. CONCLUSIONS: This large study with up to 20 years' follow-up has found that reoperation for POP is modest, that the reoperation rate is lowest for the apical compartment, but highest in all three compartments during the first year after primary surgery. The reoperation rate peaks in the group of women who had their primary surgery before the menopause in all three compartments.

Vaginal vault suspension during hysterectomy for benign indications: a prospective register study of agreement on terminology and surgical procedure.

INTRODUCTION AND HYPOTHESIS: Several suspension methods are used to try to prevent pelvic organ prolapse (POP) after hysterectomy. We aimed to evaluate agreement on terminology and surgical procedure of these methods. METHODS: We randomly chose 532 medical records of women with a history of hysterectomy from the Danish Hysterectomy and Hysteroscopy Database (DHHD). Additionally, we video-recorded 36 randomly chosen hysterectomies. The hysterectomies were registered in the DHHD. The material was categorized according to predefined suspension methods. Agreement compared suspension codes in DHHD (gynecologists' registrations) with medical records (gynecologists' descriptions) and with videos (reviewers' categorizations) respectively. Whether the vaginal vault was suspended (pooled suspension) or not (no suspension method + not described) was analyzed, in addition to each suspension method. RESULTS: Regarding medical records, agreement on terminology was good among patients undergoing pooled suspension in cases of hysterectomy via the abdominal and vaginal route (agreement 78.7, 92.3%). Regarding videos, agreement on surgical procedure was good among pooled suspension patients in cases of hysterectomy via the abdominal, laparoscopic, and vaginal routes (agreement 88.9, 97.8, 100%). Agreement on individual suspension methods differed regarding both medical records (agreement 0-90.1%) and videos (agreement 0-100%). CONCLUSIONS: Agreement on terminology and surgical procedure regarding suspension method was good in respect of pooled suspension. However, disagreement was observed when individual suspension methods and operative details were scrutinized. Better consensus of terminology and surgical procedure is warranted to enable further research aimed at preventing POP among women undergoing hysterectomy.

Hypothyroidism and urinary incontinence: Prevalence and association in a Danish, female sample from the Lolland-Falster Health study.

INTRODUCTION: We aimed to estimate the prevalence of urinary incontinence (UI) in women with hypothyroidism and subclinical hypothyroidism and to examine the association of hypothyroidism and UI. METHODS: This cross-sectional study was based on the population-based Lolland-Falster Health Study (LOFUS), Denmark. Data comprising a questionnaire, physical examination, and blood samples were collected between 2016 and 2020. Multiple logistic regression was used to estimate odds ratios (OR) and control for possible confounders: age, body mass index, diabetes, smoking, and education. RESULTS: Of 7,699 women included in the study, 7.9% had hypothyroidism, and 2.4% had subclinical hypothyroidism. The prevalence of any UI in women with hypothyroidism, subclinical hypothyroidism, and a control group (normal level of thyroid hormones) was 43.6%, 38.1%, and 39.3%, respectively. After controlling for confounders, no association between hypothyroidism and any UI (OR 1.01, 95% CI 0.85-1.20) or frequent UI (OR 1.05, 95% CI 0.84-1.32) were demonstrated. Additional, no association between subclinical hypothyroidism and any UI (OR 0.87, 95% CI 0.64-1.18) or frequent UI (OR 1.15, 95 CI 0.79-1.69) were demonstrated. CONCLUSIONS: In our female sample, the prevalence of UI was high regardless of the thyroid status. No association between hypothyroidism and any or frequent UI was demonstrated. The prevalence of hypothyroidism was 7.9%.

No evidence of association between native tissue vault suspension and risk of pelvic pain or sexual dysfunction.

OBJECTIVE: Hysterectomy is suspected of increasing risk of subsequent pelvic organ prolapse (POP). In attempt to prevent this, several suspension methods during hysterectomy on benign indication are used as a prophylactic procedure. However, possible complications to the use of prophylactic vaginal vault suspension to prevent POP are not fully investigated. We aimed to elucidate prophylactic vaginal vault suspension as a possible cause for pelvic pain and sexual dysfunction. STUDY DESIGN: We included all women registered with a total hysterectomy on benign indication and registered with a suspension method or specifically no suspension in the nationwide Danish Hysterectomy and Hysteroscopy Database (DHHD) between 10 May 2012 and 4 September 2013 (N = 3999). A postal questionnaire on pelvic pain and sexual dysfunction was sent to women 25.8 (range 23.8-28.4) months after hysterectomy. Questions were selected from a previous study as well as from the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). We used independent samples t-tests and χ2-tests for univariate analyses. In multivariable analyses, we used log-binomial - and linear regression models adjusted for risk factors of pelvic pain and sexual dysfunction, respectively. RESULTS: The response rate was 60.3% (N = 2412). Of the respondents, 88.8% (N = 2143) were registered with a suspension method and 11.2% (N = 269) were registered with specifically no suspension. Overall, pelvic pain of any kind was reported in 24.3% (N = 576) of the respondents. In adjusted log-binomial regression, suspension did not increase risk of pelvic pain compared to no suspension (RR 0.92; 95% CI 0.75 to 1.14; p-value 0.45). In adjusted linear regression, suspension was significantly associated with less degree of sexual dysfunction (regression coefficient -0.92; 95% CI -1.70 to -0.14; p-value 0.02). CONCLUSIONS: In women undergoing prophylactic vaginal vault suspension during hysterectomy, we found less sexual dysfunction and no evidence of increased risk of pelvic pain compared to women with no vaginal vault suspension.

The handling of urinary incontinence in Danish general practices after distribution of guidelines and voiding diary reimbursement: an observational study.

BACKGROUND: Though urinary incontinence (UI) is a bothersome condition for the individual patient, the patients tend not to inform their physician about UI and the physician tend not to ask the patient. Recently different initiatives have been established in Danish general practices to improve the management of UI. The aim of this study was to identify the handling of urinary incontinence (UI) in Danish general practices after distribution of clinical guidelines and reimbursement for using a UI diary. METHODS: In October 2001, a questionnaire was sent to 243 general practitioners (GPs) in Frederiksborg County following distribution of clinical guidelines in July 1999 (UI in general practice) and September 2001 (UI in female, geriatric, or neurological patients). A policy for a small reimbursement to GPs for use of a fluid intake/voiding diary in the assessment of UI in general practice was implemented in October 2001. Information concerning monthly reimbursement for using a voiding diary, prescribed drugs (presumably used for treating UI), UI consultations in outpatient clinics, and patient reimbursement for pads was obtained from the National Health Service County Registry. RESULTS: Of the 132 (54%) GPs who replied, 87% had read the guidelines distributed 2 years before, but only 47% used them daily. The majority (69%) of the responding GPs had read and appreciated 1-3 other UI guidelines distributed before the study took place. Eighty-three percent of the responding GPs sometimes or often actively asked their patients about UI, and 92% sometimes or often included a voiding diary in the UI assessment. The available registry data concerning voiding diary reimbursement, prescribed UI drugs, UI consultations in outpatient clinics, and patient reimbursement for pads were insufficient or too variable to determine significant trends. CONCLUSION: GPs management of UI in a Danish county may be reasonable, but low response rate to the questionnaire and insufficient registry data made it difficult to evaluate the impact of different UI initiatives.

Obstructive sleep apnea in a Danish population of men and women aged 60-80 years with nocturia.

INTRODUCTION AND HYPOTHESIS: The aim of the present study was in a case-control design to evaluate the association between nocturia and obstructive sleep apnea, in men and women who had nocturia ≥ 2 per night (nocturics) compared to those without nocturia (controls). METHODS: Participants were randomly selected among respondents in a population study of 4000 elderly individuals. Nocturia was assessed using the validated Nocturia, Nocturnal Enuresis, and Sleep-interruption Questionnaire (NNES-Q). Nocturia (≥ 2 voids/night) or control (< 1 void/night) status was assessed by a 3-day frequency volume chart (FVC). Furthermore, all participants completed an overnight ambulatory polygraphic recording to identify obstructive sleep apnea (OSA). RESULTS: Of 1111 eligible individuals, a total of 75 nocturics and 75 controls (13.5%) were included. Overall, the prevalence and severity of OSA among nocturics and controls was not significantly different. In a sub-analysis we found that 22 nocturics with OSA (69%) had nocturnal polyuria. This led to a significantly increased risk of having OSA (OR 2.8, 95% CI: 1.1-7.3, p < 0.05) when having nocturnal polyuria compared to other pathophysiological causes of nocturia (polyuria, low bladder capacity, a combination of nocturnal polyuria/low bladder capacity, and neither nocturnal polyuria/low bladder capacity). CONCLUSIONS: Nocturia twice or more was not significantly associated with OSA. However, nocturics with nocturnal polyuria had a significantly higher risk of having OSA than nocturics with other pathophysiologies.

Sexual activity and lower urinary tract symptoms.

Lower urinary tract symptoms (LUTS) have a profound impact on women's physical, social, and sexual well being. The LUTS are likely to affect sexual activity. Conversely, sexual activity may affect the occurrence of LUTS. The aims of the study were to elucidate to which extent LUTS affect sexual function and to which extent sexual function affect LUTS in an unselected population of middle-aged women in 1 year. A questionnaire was sent to 4,000 unselected women aged 40-60 years. All 2,284 women (57.1%) who completed a baseline questionnaire and a similar questionnaire 1-year later were included. Data comprised age, occurrence of LUTS, hormonal status, and sexual activity. A multiple conditional logistic regression model was used to analyze the relationship between sexual activity and LUTS adjusted for age and hormonal status. At baseline and 1-year later, 49 women (2.2%) had no sexual intercourse, and 298 women (13.0%) either ceased or resumed sexual relationship. Compared to women having sexual relationship, a statistically significant three to sixfold higher prevalence of LUTS was observed in women with no sexual relationship. In women who ceased sexual relationship an increase, although not statistically significant, in the de novo occurrence of most LUTS was observed. In women who resumed sexual relationship an insignificantly decrease in LUTS was observed. In women whose sexual activity was unchanged no change in the occurrence of LUTS was observed. Our study confirms a close association between sexual activity and the occurrence of LUTS. A hypothesis that sexual inactivity may lead to LUTS and vice versa cannot be rejected.

A comparison of three methods to evaluate maximum bladder capacity: cystometry, uroflowmetry and a 24-h voiding diary in women with urinary incontinence.

BACKGROUND: Maximum bladder capacity (MBC) is an important parameter in the evaluation of lower urinary tract function. Yet, there is no consensus on how to measure MBC. The aim of this study was to compare estimates of the maximum bladder capacity (MBC) using cystometry, uroflowmetry, and a 24-h voiding diary in women with urinary incontinence. METHODS: From 1 January 1998 to 31 December 1998 a retrospective review comprising 60 incontinent women in whom cystometry, uroflowmetry, and a 24-h voiding diary were performed were evaluated. RESULTS: Median age was 55 years (range: 34-90 years). In women with detrusor instability (DI), MBC was significantly higher when measured using a voiding diary (median: 400 ml) as compared with cystometry (median: 215 ml) (p = 0.017). A 'Bland-Altman plot' demonstrated poor agreement between MBC in women with DI measured using a voiding diary and cystometry, respectively. The cystometric MBC was significantly higher in women with a stable detrusor (373 ml) as compared with women with DI (215 ml) (p = 0.0027). However, in women with or without DI there were no differences between MBC measured either using a voiding diary (400 vs. 360 mL) or by uroflowmetry (260 vs. 254 ml), respectively. CONCLUSIONS: A low cystometric MBC in women with DI may be an 'artefact' caused by the cystometric procedure (catheterization and filling). The question is which measure of MBC is the best for clinical and scientific purposes.
