Variability in practice patterns in stress urinary incontinence and pelvic organ prolapse: results of an IUGA survey

Determinants of women's preferences for surgical versus conservative management for pelvic organ prolapse: a survey-based study from Italy

BACKGROUND AND OBJECTIVE

Pelvic organ prolapse (POP) affects 40% of women, with a 12%-19% lifetime surgical risk. Italy showed high practice variation in POP surgery, possibly impacting equity of access to healthcare services, a central goal of Beveridge-like health systems. According to the literature, unwarranted variation, influenced by physician attitudes or resource allocation, must be reduced. We aimed to identify determinants influencing women's choice when asked whether they prefer surgical or conservative POP management.

DESIGN, SETTING AND POPULATION

In this nationwide prospective study, we distributed a Qualtrics questionnaire via social media to any Italian women over 18 years old who voluntarily decided to participate in the survey.

INTERVENTION

A grade 3 POP scenario was presented. Women were asked how likely they would have surgery. Each woman randomly received only 1 question out of 11: 1 question was the reference question ('How likely would you have surgery?') while 10 questions contained a potential determinant influencing woman's choice ('How likely would you have surgery if…?').

OUTCOME

The outcome was the chance of choosing surgery expressed as a percentage. We analysed the effect of each factor on the outcome by using adjusted beta regression models.

RESULTS

Respondents (n=222) opted for surgery with a median probability of 61.5%. Factors significantly increasing the chance of choosing surgery were advice from physicians, the presence of a trusted physician during hospitalisation, surgical approach with low complication rates, uterine-sparing surgery, the absence of postoperative abdominal scars and nearby hospital.

CONCLUSIONS

Our findings provide health managers and policy-makers with new evidence to better understand women's decision-making and partly capture the determinants of unwarranted variation. These inputs may also be used as attributes for a future discrete choice experiment.

Incidence and Risk Factors for Genitourinary Tract Injury Within 1 Year After Surgery for Pelvic Organ Prolapse

IMPORTANCE

The rate of genitourinary tract injury (GUTI) following pelvic organ prolapse (POP) surgery is presently ill-defined and based on relatively small trials with short follow-up time. Given the potential for higher risk of injury with POP, a better understanding of this type of injury is important for patient counseling.

OBJECTIVES

The objective of this study was to identify the incidence and risk factors of GUTI related to POP surgery.

STUDY DESIGN

Women undergoing POP surgery between 2010 and 2019 were identified using Current Procedural Terminology codes in the Premier Healthcare Database. The primary outcome was GUTI, defined as bladder or ureteral injury, and vesicovaginal or ureterovaginal fistula within 1 year of surgery. Genitourinary tract injury was identified using International Classification of Diseases and Current Procedural Terminology codes. Patients were divided into those with and without GUTI. Differences between groups were evaluated using the Student t test, Wilcoxon rank-sum test, and Fisher exact test as appropriate. Multivariable logistic regression was used to evaluate the independent predictors of GUTI.

RESULTS

One hundred thirty-nine thousand one hundred fifty-eight surgical procedures for POP were captured between 2010 and 2019. The rate of GUTI was 1.10%: 0.48% bladder, 0.64% ureteral injuries, and 0.01% fistulas. The most significant variables associated with any GUTI were as follows: adhesiolysis (adjusted odds ratio [aOR], 2.64; 95% confidence interval [CI], 1.07-6.51), blood transfusion (aOR, 3.67; 95% CI, 1.34-10.04), and low-volume surgeons (<12 cases per year) (aOR, 1.68; 95% CI, 1.60-1.77), nonurologic or gynecologic surgeon specialty (aOR, 1.62; 95% CI, 1.49-2.00), and uterosacral suspension (aOR, 1.30; 95% CI, 1.13-1.49).

CONCLUSIONS

The rate of GUTI following POP surgery is lower than has previously been reported. Surgeon experience and specialty and surgical approach may affect GUTI incidence.

Cost-Effectiveness of Prophylactic Retropubic Sling at the time of Vaginal Prolapse Surgery

BACKGROUND

Prophylactic midurethral sling (MUS) at the time of prolapse repair significantly reduces risk of de novo stress urinary incontinence (SUI), but it is associated with some small but significant morbidities. Since there has not been a standardized approach to MUS utilization, decision analysis provides a method to evaluate the cost and effectiveness associated with varying MUS strategies in addressing risk of de novo SUI.

OBJECTIVES

We aimed to compare the cost-effectiveness of the three MUS utilization strategies in treating de novo SUI one year following vaginal prolapse repair. The three approaches are: 1) staged strategy: prolapse repair without prophylactic MUS, 2) universal sling: prolapse repair with prophylactic MUS, and 3) selective sling: prolapse repair with prophylactic MUS only in patients with a positive prolapse-reduced cough stress test (CST).

STUDY DESIGN

We created a decision analysis model to compare staged strategy, universal sling, and selective sling. We modeled probabilities of de novo SUI, patients choosing subsequent MUS surgery for de novo SUI, and outcomes related to MUS. De novo SUI rates were determined for each strategy from published data. Likelihood of patients with de novo SUI choosing MUS surgery as their first-line treatment was also determined from the literature, and this scenario was only applied to patients without prophylactic MUS at their index prolapse repair. Finally, outcomes related to MUS including recurrent or persistent SUI, voiding dysfunction requiring sling lysis, mesh exposure requiring excision, and de novo overactive bladder requiring medications were all derived from publicly available data. All MUS was assumed to be retropubic. The costs for each procedure were obtained from the 2020 Centers for Medicare & Medicaid Services Physician Fee Schedule or previous literature converted to 2020 US dollars with the Consumer Price Index. The primary outcome was modeled as the incremental cost effectiveness ratio (ICER). We performed multiple one-way sensitivity analyses to assess model robustness.

RESULTS

The lowest cost strategy was the staged strategy which costs $1,051.70 per patient, followed by $1,093.75 for selective sling and $1,125.54 for universal sling. The selective sling approach, however, had the highest health utility value; therefore, universal sling was dominated by selective sling as it is both less costly and more effective. When compared to the staged strategy, selective sling was cost-effective with ICER of $2,664/QALY, meeting the predetermined threshold. In multiple 1-way sensitivity analyses, the variable with the largest effect was the percentage of patients electing to undergo subsequent MUS surgery for de novo SUI after index surgery. Only when this proportion exceeded 62% did universal sling become the cost-effective option as selective sling surpassed the predetermined ICER threshold and became dominated.

CONCLUSION

Selective sling was the preferred and cost-effective strategy in treating de novo SUI one year following vaginal prolapse repair. Surgeons should counsel their patients preoperatively regarding the possibility of de novo SUI after prolapse repair as well as the benefits and risks of prophylactic MUS.

Exploring literature on knowledge, attitudes, beliefs and practices towards urinary incontinence management: a scoping review

INTRODUCTION AND HYPOTHESIS

Urinary incontinence affects women of all ages, influencing 8.5% of the world's population in 2018. Effective management of urinary incontinence is influenced by patients help-seeking behaviour and services offered by healthcare professionals within the healthcare system. To facilitate behavioural change, it is important to understand the knowledge(Knowledge: "the comprehension and understanding of acquired facts or information about UI in adults"), attitudes (Attitude: "a predisposed perspective which influences nurses' thoughts, feelings, perceptions and behaviours towards care of adults with UI") and beliefs (Beliefs: "a theoretically conceptualized conviction or expectation regarding UI in general") of healthcare practitioners towards urinary incontinence management. The aim of this review is thus to systematically map the existing literature, reporting on how knowledge, attitude, belief and practices towards urinary incontinence management have been explored.

METHODS

Six databases were systematically searched. Included studies were published between January 2013 to January 2020 in English, investigating urinary incontinence management in women.

RESULTS

The search yielded 39 studies, with data emanating from 16 counties. Quantitative, Qualitative and mixed methodologies were used to explore the four concepts of knowledge, attitudes, beliefs and practices. A wide range of healthcare practitioners were questioned and management was explored in five healthcare settings. All factors explored related to the four concepts are reported and factors reaching consensus in included literature were highlighted.

CONCLUSION

The summarized factors can assist further investigations into the four concepts to change healthcare practitioner's behaviour towards urinary incontinence management.

Factors associated with the prescription of vaginal pessaries for pelvic organ prolapse

OBJECTIVE

To identify the factors associated with the prescription of vaginal pessaries (VPs) as a conservative treatment for pelvic organ prolapse (POP).

METHODS

A cross-sectional study was performed during two annual urogynecology and general obstetrics and gynecology meetings in 2017 (São Paulo, SP, Brazil). A 19-item deidentified questionnaire regarding experiences and practices in prescribing VPs for POP patients was distributed among gynecologists. Our primary outcome was the frequency of prescribing VPs as a conservative treatment for POP. The reasons for prescribing or not prescribing VPs were also investigated. Univariate and multivariate analyses with crude and adjusted odds ratios (ORs) were performed for variables associated with the prescription of pessaries.

RESULTS

Three hundred forty completed surveys were analyzed. Half of the respondents (53.53%) were between 30-49 years old; most of them were female (73.53%), were from the Southeast Region (64.12%), were trained in obstetrics and gynecology (80.24%) or urogynecology (61.18%) and worked in private offices (63.42%). More than one-third (36.48%) attended four or more POP cases/week, and 97.65% (n=332) had heard or knew about VPs for POP; however, only 47.06% (n=160) prescribed or offered this treatment to patients. According to the multivariate analysis, physicians aged 18-35 years (OR=1.97[1.00-3.91]; p=0.04), those who participated in a previous urogynecology fellowship (OR=2.34[1.34-4.09]; p<0.01), those with relatively high volumes of POP cases (4 or +) (OR=2.23[1.21-4.47]; p=0.01) and those with PhD degrees (OR=2.75[1.01-7.54]; p=0.05) prescribed more pessaries.

CONCLUSIONS

Most gynecologists did not prescribe VPs. Younger physician age, participation in a previous urogynecology fellowship, a PhD degree, and a relatively high volume of POP cases were associated with increased VP prescription rates.

Pessários vaginais na incontinência urinária: revisão integrativa

Objetivo: Analisar os tipos de pessários, as indicações e o impacto no tratamento da incontinência urinária (IU). Métodos: Trata-se de revisão integrativa com publicações de 2007 a 2017 indexadas nas bases de dados Biblioteca Virtual em Saúde, Medical Literature Analysis and Retrieval System Online, Scopus Info Site, Cumulative Index to Nursing and Allied Health Literature e Web of Science. Resultados: Selecionaram-se oito artigos. Os pessários indicados foram prato, anel, Uresta® e Contiform®. A redução ou resolução da IU de esforço (IUE) em mulheres foi observada por análise de parâmetros objetivos, como avaliação urodinâmica e questionários de qualidade de vida. Destacou-se viabilidade econômica. Evidenciaram-se desajuste, dificuldades no uso, incômodo e manutenção de perdas urinárias entre os motivos de não adesão. Prolapso avançado e comprimento vaginal curto foram preditivos de insucesso. Identificaram-se eventos adversos em baixa incidência: retenção urinária e leucorreia. Conclusão: A terapia pessária é eficaz no tratamento da IUE quando acompanhada por profissionais capacitados. Características individuais e percepções sobre o dispositivo são determinantes no sucesso terapêutico. Estudos de maior amostragem, tempo de seguimento e qualidade, bem como estimulo a publicações nacionais, são necessários para investigação de medidas objetivas de IU, fatores clínicos e demográficos em relação ao sucesso do pessário.

Vaginal pessaries in urinary incontinence: integrative review

Objectives: To analyze the types of pessaries, indications and impact in the treatment of urinary incontinence (UI). Methods: This is an integrative review with publications from 2007 to 2017 indexed in the Biblioteca Virtual em Saúde, Medical Literature Analysis and Retrieval System Online databases, Scopus Info Site, Cumulative Index to Nursing and Allied Health Literature and Web of Science. Results: Eight articles were selected. The pessaries indicated were the dish, ring, Uresta®, and Contiform®. The reduction or resolution of stress UI in women was observed by analysis of objective parameters such as urodynamic evaluation and quality of life questionnaires. Economic viability was highlighted. Disability, difficulties in use, discomfort, and maintenance of urinary losses were evidenced among the reasons for non-adherence. Advanced prolapse and short vaginal length were predictive of failure. Adverse events were identified in low incidence: urinary retention and leukorrhea. Conclusion: Pessary therapy is effective in the treatment of SUI when accompanied by trained professionals. Individual characteristics and perceptions about the device are determinants of therapeutic success. Studies of greater sampling, follow-up time and quality, as well as stimulation to national publications, are necessary for the investigation of objective measures of UI, clinical and demographic factors in relation to the success of the pessary.

An Internet-based survey to evaluate the comfort and need for further pubovaginal sling training

INTRODUCTION AND HYPOTHESIS

The pubovaginal sling (PVS) dates to the 1940s as an efficacious surgical treatment for stress urinary incontinence (SUI). Recently, it has been replaced by the midurethral sling (MUS). Since 2008, international regulatory agencies increased regulation and issued warnings on vaginal mesh for repair of pelvic organ prolapse (POP), which has led to increased scrutiny of the MUS. Thus, the need for surgical comfort with PVS is resurfacing. We sought to evaluate the surgical practice patterns among international urogynecologists for the treatment of SUI and identify whether a need and interest for more training exists.

METHODS

We developed a short, Internet-based survey for members of the International Urogynecological Association (IUGA). Descriptive analyses, binomial and multivariate logistic regressions were calculated to determine significant associations.

RESULTS

Among 556 members who responded to the survey, 72% did not offer PVS in practice. Among those who did, there was as significant relationship between offering PVS and practicing in the United States, board-certification in urogynecology, PVS exposure in training, increasing number of PVS performed during training, and comfort with PVS. Members interested in further PVS training were younger, less comfortable with PVS, performed fewer PVS, or had no exposure in training.

CONCLUSION

Most IUGA members do not offer PVS in clinical practice. As would be expected, members who performed more PVS in training and were more comfortable with PVS were likely to offer it to patients. Our results highlight a learning gap, especially among younger providers who are not comfortable with PVS and desire further training in this procedure.

Documenting pessary offer prior to hysterectomy for management of pelvic organ prolapse

OBJECTIVES

To (1) determine the proportion of hysterectomy cases with documentation of pessary counseling prior to prolapse surgery and (2) identify variables associated with women offered a pessary.

STUDY DESIGN

The Michigan Surgical Quality Collaborative (MSQC) is a hysterectomy improvement initiative. Hysterectomies from 2013 to 2015 in which prolapse was the principal diagnosis were included. "Pessary offer" was defined as documentation showing the patient declined, could not tolerate, or failed a pessary trial. Bivariate analyses were used to compare demographics, medical history, surgical route, concomitant procedures (colpopexy or colporrhaphy), and intra- and postoperative complications between women with and without pessary offer. Hierarchical logistic regression was used to determine factors independently associated with pessary offer. Risk-adjusted pessary offer rates by hospital were calculated.

RESULTS

The adjusted rate of pessary offer was 25.2%, ranging from 3 to 76% per hospital. Bivariate comparisons showed differences between women with and without pessary offer in age, tobacco use, prior pelvic surgery, insurance status, surgical approach, secondary indication for surgery, concomitant prolapse procedure, teaching hospital status and hospital bed size. In logistic regression, odds of pessary offer increased with age > 55 years (OR 1.45, 95% CI 1.12-1.88, p = 0.006), Medicare insurance (OR 1.65, 95% CI 1.30-2.10, p < 0.0001), and a concomitant procedure (OR 1.5, 95% CI 1.16-1.93, p = 0.002). Postoperative urinary tract infections were more common in patients offered a pessary (6.4% vs. 2.5%, p < 0.0001), but other complications were similar.

CONCLUSIONS

Overall, only one-quarter of hysterectomies for prolapse in MSQC hospitals had documentation of pessary counseling-suggesting an opportunity to improve documentation, counseling regarding pessary use, or both.

Pessary use in stress urinary incontinence: a review of advantages, complications, patient satisfaction, and quality of life

Stress urinary incontinnce (SUI) is a common condition among women. The usual approach to treatment of SUI is a stepwise plan from conservative to surgical procedures. A vaginal pessary is one of the commonly used conservative treatments that offer symptomatic improvement for women with incontinence. This review provides a critical analysis of the benefits and shortcomings offered by vaginal pessaries to patients affected by SUI, with a particular focus on indications, advantages, quality of life, patient satisfaction, and potential complications. To obtain the required information, an extensive search of PubMed and Cochrane databases was performed, covering the time frame from January 2000 to December 2016. We also surveyed the published guidelines of American Urological Association, Canadian Urological Association, American Urogynecological Society, National Institutes of Health (USA), and National Institute for Health and Care Excellence (UK). A total of 192 original research papers, review articles, and clinical trials were identified. The analysis of retrieved data provides evidence that vaginal pessaries constitute an effective nonsurgical option for SUI. The satisfaction rate with pessary use is high and only minor complications, if any, occur, vaginal discharge being the most common. The reviewed studies document that vaginal pessaries provide an adequate control of SUI if they are fit properly and managed by frequent replacements and regular checkups. They should be considered among the first line of treatment for SUI associated with exercise and increased intra-abdominal pressure.

The Urological Society of India survey on urinary incontinence practice patterns among urologists

Introduction:

The Urological Society of India guidelines panel on urinary incontinence (UI) conducted a survey among its members to determine their practice patterns in the management of UI. The results of this survey are reported in this manuscript.

Methods:

An anonymous online survey was carried out among members of the USI to determine their practice patterns regarding UI using a predeveloped questionnaire on using SurveyMonkey^®. A second 4-question randomized telephonic survey of the nonresponders was performed after closure of the online survey. Data were analyzed by R software 3.1.3 (P < 0.05 significant).

Results:

A total of 468 of 2109 (22.2%) members responded to the online survey. Nearly 97% were urologists, 74.8% were working at a private, and 39.4% were in an academic institution. Almost all were managing UI. 84.2% had local access to a urodynamics (UDS) facility. 85.8% would check postvoid residual urine for all the patients. Voiding diary, symptom scores, quality of life scores, pad test, Q-tip test, stress test, uroflow, and cystoscopy were ordered as part of evaluation by 86.0%, 49.8%, 24.4%, 22.0%, 6.0%, 71.8%, 69.2%, and 34.7%, respectively. 47.6% would order a UDS for patients with urgency UI who fail conservative treatment. 36.9% would get UDS prior to all stress UI surgery. Seventy-five percent would make a diagnosis of intrinsic sphincter deficiency. Solifenacin was the first choice for urgency UI in general and darifenacin was preferred in elderly. Botulinum was the first choice for refractory urgency UI. Midurethral sling was the commonest procedure for surgical management of SUI (95.1%). 147 of the 1641 non responders were randomly sampled telephonically. Telephonic respondents had similar access to UDS facility but had performed fewer lifetime number of post-prostatectomy incontinence (PPI) surgeries. Combining data from both surveys, total number of artificial sphincters and PPI surgeries ever performed by USI members was estimated at 375 and 718 respectively.

Conclusion:

This survey provides important new data and elicits critical differences in management practices based on demographics.

Transobturator midurethral sling: What should patients expect after surgery?

INTRODUCTION AND HYPOTHESIS

Midurethral sling (MUS) surgeries are minimally invasive procedures; however, they are not free of postoperative complications. The aim of the study was to assess the occurrence of lower urinary tract symptoms (LUTS) (urgency, nocturia, frequency, splitting/spraying, hesitancy, terminal dribbling, and subjective feeling of postvoid residual) in patients suffering from stress (SUI) or mixed (MUI) urinary incontinence with a predominant SUI component before and after transobturator MUS placement.

METHODS

The study group consisted of 88 women with SUI and 18 with MUI who underwent transobturator MUS. All participants were questioned with a self-developed questionnaire before and after surgery regarding the presence of LUTS.

RESULTS

Seven days after surgery, 62 patients (58.5%) noted voiding and postmicturition symptoms, whereas 67 (63.2%) reported problems in storage. The more commonly reported LUTS at week 1 after surgery were urgency (52.8%), splitting/spraying (41.5%), and feeling of incomplete bladder emptying (34.0%). Patients perceived that splitting/spraying was the most bothersome. After 6 months, the most common LUTS reported were hesitancy (14.1%), terminal dribbling (10.4%), and splitting/spraying (9.4%). We noticed a decrease in the number of urgency episodes >2.7 times (p < 0.001) compared with baseline. After 6 months, 97 (91.5%) patients reported the lack of incontinence episodes.

CONCLUSIONS

A vast majority of patients after MUS suffer from LUTS in the early postoperative period; however, the majority of undesired symptoms resolve spontaneously within the first 6 months postsurgery.
