The "1-3-5 cough test": comparing the severity of urodynamic stress incontinence with severity measures of subjective perception of stress urinary incontinence

Instruments Used for the Assessment of SUI Severity in Urogynecologic Surgical Trials: A Scoping Review

INTRODUCTION AND HYPOTHESIS

Various instruments are used to evaluate the severity of stress urinary incontinence (SUI) in clinical trials for SUI surgery. We conducted a scoping review with the primary aim of investigating the use of such instruments.

METHODS

A comprehensive search in PubMed/MEDLINE, Cochrane Library, ClinicalTrials.gov, and WHO ICTRP was carried out. Inclusion criteria were studies including patients undergoing surgical intervention for SUI with assessment of SUI severity performed pre- and post-operatively. Exclusion criteria were nonprospective studies, nonrandomized studies, studies not in the English language, and the absence of reporting the methods of SUI severity evaluation in the study.

RESULTS

In total, 8,886 articles were identified, yielding 100 papers for data extraction. The most frequent interventions were mid-urethral slings (85 studies), Burch colposuspension (10 studies), and the use of bulking agents (3 studies). The most frequently used instruments for objective evaluation of SUI were urodynamics (90 studies), nonvalidated cough stress test (83 studies), and 1-h pad test (28 studies). The most frequently used instruments for subjective evaluation were bladder diary (37 studies), Incontinence Impact Questionnaire-7 (26 studies), and Urinary Distress Inventory-6 (23 studies). There were three studies reporting results according to the severity of pre- and post-operative SUI.

CONCLUSIONS

There is significant heterogeneity regarding the instruments used to evaluate the severity of SUI in surgical trials for female incontinence. There is a paucity of data regarding results according to the pre-operative severity of SUI. Hence, commonly agreed standardized methods for the assessment of SUI severity are needed to improve comparability between clinical trials for SUI surgery.

Macroplastique Is a Safe and Effective Long-term Surgical Treatment for Stress Urinary Incontinence: Prospective Study with 10-Year Follow-up

BACKGROUND AND OBJECTIVE

Until a few years ago, a midurethral sling was considered the gold standard for the treatment of female stress urinary incontinence (SUI) after failure of conservative therapies. However, criticisms regarding the rate of mesh exposure and lack of long-term efficacy have led to reconsideration of other surgical procedures. Our aim was to investigate long-term subjective and objective outcomes after injection of Macroplastique, a urethral bulking agent.

METHODS

We prospectively enrolled all consecutive women complaining of pure SUI symptoms with urodynamically proven SUI who received a Macroplastique injection. We investigated patient-reported subjective outcomes using International Consultation on Incontinence Questionnaire-Short Form, Urogenital Distress Inventory, Patient Global Impression of Improvement, and Visual Analog Scale (VAS) questionnaires, and the cough stress test to assess objective outcomes. Adverse events were recorded during follow-up.

KEY FINDINGS AND LIMITATIONS

At 10 yr after Macroplastique injection, the objective cure rate was 56% and 71% of patients reported that they were satisfied. Long-term data revealed no significant decline in subjective or objective cure rates. No serious complications were reported. Study limitations include the small sample size and the lack of pad tests and bladder diaries for postoperative evaluations.

CONCLUSIONS AND CLINICAL IMPLICATIONS

Our study shows that Macroplastique injection can be an effective and safe option for the treatment of female SUI in the long term, even when used in the first-line setting.

PATIENT SUMMARY

We evaluated outcomes for women with stress urinary incontinence (SUI) who were treated with an injection of Macroplastique gel into the wall of the urethra to prevent leakage of urine. We found that this is a safe option for treatment of female SUI that is effective in the long term.

Platelet-Rich Plasma for the Treatment of Stress Urinary Incontinence-A Randomized Trial

IMPORTANCE

Urinary incontinence affects millions of women worldwide.

OBJECTIVE

The aim of the current study was to evaluate the efficacy and safety of periurethral platelet-rich plasma (PRP) injections in women with stress urinary incontinence (SUI).

STUDY DESIGN

This was a single-center, double-blind, randomized sham-controlled trial. Fifty participants with SUI and urodynamic stress incontinence were randomized in 2 equally sized groups. Women in the PRP group received 2 PRP injections at 3 levels of the urethra at 4- to 6-week intervals. Women in the sham group were injected with sodium chloride 0.9%. At baseline, participants underwent urodynamic studies and a 1-hour pad test and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), the Patient Global Impression Scale of Improvement, and the King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), women underwent the 1-hour pad test and completed the King's Health Questionnaire and the ICIQ-FLUTS. Primary outcome was the subjective evaluation as indicated by the response to question 11a of the ICIQ-FLUTS questionnaire. Secondary outcomes included scores of questionnaires and urine loss assessed on the 1-hour pad test. The level of discomfort during injections and any adverse events were also evaluated.

RESULTS

During follow-up, the mean score of the 11a question decreased significantly in the PRP group compared with sham. Subjective cure was significantly higher in the PRP group (32% vs 4%, P < 0.001). A significant reduction of urine loss assessed on the 1-hour pad test was observed in the PRP group compared with the sham group at 6-month follow-up. No adverse events were observed.

CONCLUSIONS

Periurethral PRP injections were superior to sham injections in improving SUI symptoms with an excellent safety profile.

Treatment outcome of women with urodynamic mixed urinary incontinence: an observational study

INTRODUCTION AND HYPOTHESIS

Mixed urinary incontinence (MUI) is a common yet understudied condition. It remains a therapeutic challenge, with the presence of both stress urinary incontinence (SUI) and urgency urinary incontinence (UUI). There is limited information on the optimal management for women with urodynamic MUI (urodynamic stress incontinence and detrusor overactivity). We assessed the treatment outcome of pelvic floor muscle training (PFMT), medical treatment and surgery for women who were diagnosed with urodynamic MUI.

METHODS

A prospective observational study was carried out on women with urodynamic MUI from 2010 to 2018. All women underwent clinical assessment and standardised urodynamic evaluation. All women received PFMT from a specialised continence advisor as initial management. Antimuscarinics and/or continence surgery were considered according to the woman's response and symptoms after PFMT. Subjective outcome after each treatment modality was analysed.

RESULTS

A total of 198 women were included for analysis. All women received PFMT, 104 (52.5%) showing improvement in urinary incontinence. Eighty-seven (43.9%) women were offered antimuscarinics, of whom 58 (29.3%) showed subjective improvement in both SUI and UUI, and 10 (5%) reported a reduction in UUI but persistent SUI. A total of 55 (27.7%) women received surgical treatment, with 20 receiving continence procedures. Sixteen out of twenty (80%) of them reported improvement in both SUI and UUI. None reported worsening of urgency or UUI. Overall, across all treatment modalities, 73.8% of women showed improvement in both SUI and UUI.

CONCLUSION

Future analyses can help to inform which patients will have a higher success rate after each treatment modality and help focus treatment effort on those with a high risk of persistent symptoms. This will provide relevant data in counselling women, giving reasonable expectations and directing the management of women with urodynamic MUI.

Is urodynamic evaluation able to change and improve the management of women with idiopathic overactive bladder?

BACKGROUND

For women with overactive bladder (OAB), current guidelines recommend the use of urodynamic studies (UDS) only in complicated cases. This study aimed to investigate whether UDS can also be helpful in uncomplicated cases. Specific aims of the study were: 1) to evaluate objective benefit and subjective patient satisfaction with tailored treatment based on the UDS diagnosis compared to the outcomes of the pharmacological treatment only based on the symptoms; 2) to investigate the correlation between symptoms and UDS findings in women with uncomplicated idiopathic OAB symptoms; 3) to assess the ability of UDS to modify management decisions in these patients.

METHODS

Women presenting to our clinic with a history of uncomplicated OAB symptoms for the past three months or more, and who completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), were considered for this study. We proposed UDS to all participants. In women who accepted UDS (group 1), management decisions were made on the basis of urodynamic findings and post-treatment evaluation was scheduled at three months. The outcomes of treatments in these patients were compared to the results in women who did not accept UDS and who received pharmacological treatment symptoms-based (group 2). Objective outcomes were based on completion of a 3-day micturition diary. Subjective outcomes were captured using the Overactive Bladder Questionnaire Short Form (OABq-SF), the Patient Global Impression of Improvement (PGI-I) scale, and a patient satisfaction scale.

RESULTS

A total of 680 women were enrolled in the study; 478 underwent UDS and 202, at the contrary, declined UDS. In 53.6% of cases, UDS led to modification of the proposed management approach. At the 3-month follow-up, the overall patient satisfaction rate in group 1 and group 2 was 77% and 65.8%, respectively (P=0.003).

CONCLUSIONS

We showed that OAB management tailored according to the UDS diagnosis results in higher subjective satisfaction if compared with a pharmacological treatment symptoms-based. Our study confirmed a lack of correlation between OAB symptoms and the urodynamically proven diagnosis of detrusor overactivity (DO). It also suggested that UDS can determine the underlying pathophysiology of every woman with OAB syndrome, whether complicated or uncomplicated, allowing treatment to be appropriately tailored with better results.

The Use of Platelet-rich Plasma as a Novel Nonsurgical Treatment of the Female Stress Urinary Incontinence: A Prospective Pilot Study

OBJECTIVES

The aim of the study was to evaluate the efficacy and safety of platelet-rich plasma (PRP) for the treatment of stress urinary incontinence (SUI).

METHODS

This was a prospective observational pilot study conducted in a tertiary referral unit, enrolling women with SUI booked for SUI surgery. A total of 20 consecutive women met the inclusion criteria and attended all follow-ups. All participants underwent 2 PRP injections into the lower one third of the anterior vaginal wall at 4- to 6-week intervals. At baseline, they underwent urodynamic studies, a 1-hour pad test, and completed the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms and King's Health Questionnaire. At follow-up visits (1, 3, and 6 months), patients underwent the 1-hour pad test and completed the King's Health Questionnaire, International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms, and Patient Global Impression Scale of Improvement. Primary outcome was to evaluate posttreatment SUI. Secondary outcomes included assessment of patient-reported questionnaires, assessment of urine loss (1-hour pad test), and the level of discomfort during injections (visual analog scale score). Statistical analysis was performed before PRP and 1, 3, and 6 months after the last treatment.

RESULTS

A significant improvement in SUI symptoms was observed 3 months after treatment with a further improvement at 6 months. A mean reduction of 50.2% in urine loss was observed in the 1-hour pad test. At the 6-month follow-up, 80.0% of women reported to be at least improved. No adverse effects were observed.

CONCLUSIONS

Platelet-rich plasma injections were both effective and safe at least in the short term and could be offered as an alternative outpatient procedure for the treatment of SUI. However, these encouraging findings warrant further investigation with randomized controlled trials.

Efficacy and safety of polydimethylsiloxane injection (Macroplastique® ) for the treatment of female stress urinary incontinence: results of a series of 85 patients with ≥3 years of follow-up

OBJECTIVE

To assess the long-term efficacy and safety of polydimethylsiloxane injection (Macroplastique® , Cogentix Medical, Orangeburg, New York, USA) for the treatment of female stress urinary incontinence (SUI), with a minimum follow-up of 3 years.

PATIENTS AND METHODS

This is an observational analytical prospective cohort study conducted in a single uro-gynaecological unit. All consecutive women with urodynamically confirmed pure SUI treated with the Macroplastique procedure, were included. Data regarding patient outcomes (International Consultation on Incontinence Questionnaire-Short Form, Patient Global Impression of Improvement, and patient satisfaction scores), objective cure rates, and adverse events were collected during follow-up. Uni- and multivariable analyses were performed to investigate outcomes. Multiple logistic regression was performed to identify factors involved in the risk of failure of the procedures or recurrence of SUI.

RESULTS

In all, 85 women had the Macroplastique procedure. At the 3-year follow-up, all 85 (100%) patients were available for the evaluation. We did not find any significant change in the surgical outcomes during this time. At 3 years after surgery, 42 of 85 patients (49%) declared themselves cured (P = 0.67). Similarly, at the 3-year evaluation, 40 of 85 patients (47%) were objectively cured. There was no significant deterioration of objective cure rates over time (P = 0.3). A history of radical pelvic surgery and a low surgeon's skill were significantly associated with the risk of failure of Macroplastique. The multivariate analysis confirmed these findings; a previous history of radical pelvic surgery and a low surgeon's skill independently predicted the subjective and objective failure of Macroplastique.

CONCLUSIONS

The 3-year results of this study showed that Macroplastique could be an acceptable alternative for the treatment of SUI with stable results over time and a negligible complication rate.

Investigation of pelvic floor disorders

Pelvic floor disorders (PFDs) are a common and complex problem encompassing a broad spectrum of conditions such as urinary incontinence, voiding difficulties, pelvic organ prolapse, anal incontinence, and chronic pelvic pain. The initial assessment of women with PFDs is based on a detailed and focused history and a holistic clinical evaluation of the pelvic floor. Other investigations may be used in clinical practice for the determination of the pathophysiology and the severity of the PFDs. In the field of urogynecology, urodynamic studies, ultrasound, and magnetic resonance imaging of the pelvic floor are currently implemented in the diagnostic work-up of women with PFDs. These provide valuable information not only on the anatomic integrity but also on the function of the pelvic floor which may not be apparent from the clinical examination. The provision of such information is complementary to the patient's symptoms and degree of bother and enables the implementation of a targeted treatment plan, thus maximizing the likelihood of cure and minimizing the risk of treatment complications.

Fertility outcomes following obstetric fistula repair: a prospective cohort study

BACKGROUND

Obstetric fistula (OF) is a maternal morbidity associated with high rates of stillbirth, amenorrhea, and sexual dysfunction. Limited data exists on the reproductive outcomes of women in the years following a fistula repair. The objective of this study is to describe the fertility outcomes and family planning practices in a population of Malawian women 1-4 years after fistula repair.

METHODS

Women who had enrolled into a clinical database of OF patients and undergone OF repair between January 1, 2012 and July 31, 2014 were recruited and enrolled to complete a home-based survey of their demographic and reproductive health data 1-4 years after their repair. Pregnancy, amenorrhea, and sexual function were described using frequency analysis, and we compared antimüllerian hormone (AMH) concentrations between women with menses or pregnancy with women with amenorrhea or no pregnancy using Wilcoxon rank sum tests.

RESULTS

Of 297 women with a prior OF repair, 148 had reproductive potential and were included in this analysis. Overall 30 women of these women (21%) became pregnant since their fistula repair, with most pregnancies ending with cesarean delivery. Of the 32 women who were amenorrheic at the time of repair, 25 (78.1%) had resumption of menses. Only 11 (8.6%) of sexually active women reported dyspareunia, and among women who were not trying to conceive, 53.1% were currently using a method of family planning. No significant differences were found in AMH concentrations between those who were pregnant or had menses versus those without pregnancy or menses, respectively.

CONCLUSIONS

In this long-term follow-up study of women after OF repair, many women were able to achieve a pregnancy with a live birth, have normal menses, be sexually active, and access contraception. These achievements will further assist a population of women whose reintegration and restoration of dignity is closely tied to their ability to achieve their reproductive goals.
