Non-Surgical Management of Urinary Incontinence

Author/s: 
Ranna Al-Dossari, Monica Kalra, Julie Adkison, Bich-May Nguyen

Urinary incontinence management varies depending on the type of incontinence and severity of symptoms. Types of incontinence include stress (SUI), urge or overactive bladder (OAB), mixed, neurogenic, and overflow incontinence. First-line treatment for OAB and SUI is nonpharmacologic management. Behavioral therapy is first-line treatment for urge incontinence. Vaginal mechanical devices (cones, pessaries, and urethral plugs), pelvic floor muscle training, and electroacupuncture are recommended as first-line treatment for women with SUI. Biofeedback and electric muscle stimulation can be adjunctive therapy for SUI. Antimuscarinics and β-3 agonists can be used as adjective therapy for those with OAB who do not improve with behavioral therapy. β-3 agonists have less anticholinergic side effects compared with antimuscarinics for OAB. Adverse medication effects can often lead to discontinuation due to poor tolerability. Third-line therapies are for those who fail conservative and pharmacologic therapies and lack high-grade evidence. Neuromodulation, neurotoxin injections, vaginal laser therapy, and acupuncture are third-line in OAB management. Pharmacologic management with α-1-blockers is recommended as first-line treatment for moderate to severe overflow incontinence from BPH. 5-α reductase inhibitors can be used as an adjunct medication in those with refractory overflow incontinence symptoms and a PSA ≥ 1.5 mg/dL. Clean intermittent catheterization is first-line therapy for neurogenic bladder but can increase risk of catheter-associated urinary tract infection. Clinicians should assess type of incontinence, patient goals, side effect profile, and tolerability to determine an individualized treatment plan for each patient.

Role of biofilm in catheter-associated urinary tract infection

Author/s: 
Trautner, B. W., Darouiche, R. O.

The predominant form of life for the majority of microorganisms in any hydrated biologic system is a cooperative community termed a “biofilm.” A biofilm on an indwelling urinary catheter consists of adherent microorganisms, their extracellular products, and host components deposited on the catheter. The biofilm mode of life conveys a survival advantage to the microorganisms associated with it and, thus, biofilm on urinary catheters results in persistent infections that are resistant to antimicrobial therapy. Because chronic catheterization leads almost inevitably to bacteriuria, routine treatment of asymptomatic bacteriuria in persons who are catheterized is not recommended. When symptoms of a urinary tract infection develop in a person who is catheterized, changing the catheter before collecting urine improves the accuracy of urine culture results. Changing the catheter may also improve the response to antibiotic therapy by removing the biofilm that probably contains the infecting organisms and that can serve as a nidus for reinfection. Currently, no proven effective strategies exist for prevention of catheter-associated urinary tract infection in persons who are chronically catheterized.

Importance Determination of optimal treatment durations for common infectious diseases is an important strategy to preserve antibiotic effectiveness.

Objective To determine whether 7 days of treatment is noninferior to 14 days when using ciprofloxacin or trimethoprim/sulfamethoxazole to treat urinary tract infection (UTI) in afebrile men.

Design, Setting, and Participants Randomized, double-blind, placebo-controlled noninferiority trial of afebrile men with presumed symptomatic UTI treated with ciprofloxacin or trimethoprim/sulfamethoxazole at 2 US Veterans Affairs medical centers (enrollment, April 2014 through December 2019; final follow-up, January 28, 2020). Of 1058 eligible men, 272 were randomized.

Interventions Participants continued the antibiotic prescribed by their treating clinician for 7 days of treatment and were randomized to receive continued antibiotic therapy (n = 136) or placebo (n = 136) for days 8 to 14 of treatment.

Main Outcomes and Measures The prespecified primary outcome was resolution of UTI symptoms by 14 days after completion of active antibiotic treatment. A noninferiority margin of 10% was selected. The as-treated population (participants who took ≥26 of 28 doses and missed no more than 2 consecutive doses) was used for the primary analysis, and a secondary analysis included all patients as randomized, regardless of treatment adherence. Secondary outcomes included recurrence of UTI symptoms and/or adverse events within 28 days of stopping study medication.

Results Among 272 patients (median [interquartile range] age, 69 [62-73] years) who were randomized, 100% completed the trial and 254 (93.4%) were included in the primary as-treated analysis. Symptom resolution occurred in 122/131 (93.1%) participants in the 7-day group vs 111/123 (90.2%) in the 14-day group (difference, 2.9% [1-sided 97.5% CI, –5.2% to ∞]), meeting the noninferiority criterion. In the secondary as-randomized analysis, symptom resolution occurred in 125/136 (91.9%) participants in the 7-day group vs 123/136 (90.4%) in the 14-day group (difference, 1.5% [1-sided 97.5% CI, –5.8% to ∞]) Recurrence of UTI symptoms occurred in 13/131 (9.9%) participants in the 7-day group vs 15/123 (12.9%) in the 14-day group (difference, –3.0% [95% CI, –10.8% to 6.2%]; P = .70). Adverse events occurred in 28/136 (20.6%) participants in the 7-day group vs 33/136 (24.3%) in the 14-day group.

Conclusions and Relevance Among afebrile men with suspected UTI, treatment with ciprofloxacin or trimethoprim/sulfamethoxazole for 7 days was noninferior to 14 days of treatment with regard to resolution of UTI symptoms by 14 days after antibiotic therapy. The findings support the use of a 7-day course of ciprofloxacin or trimethoprim/sulfamethoxazole as an alternative to a 14-day course for treatment of afebrile men with UTI.

Nonsurgical Treatments for Urinary Incontinence in Women: A Systematic Review Update

Author/s: 
Balk, Ethan, Adam, Gaelen P., Kimmel, Hannah, Rofeberg, Valerie, Saeed, Iman, Jeppson, Peter, Trikalinos, Thomas

Introduction. About 17 percent of adult women have had urinary incontinence (UI), classified as stress, urgency, or mixed. Stress UI is associated with an inability to retain urine with activities that increase intraabdominal pressure. Urgency UI is associated with the sudden, compelling urge to void. Mixed UI occurs when both are present.

Methods. We updated the Agency for Healthcare Research and Quality's 2012 systematic review with new literature searches in MEDLINE®, the Cochrane Central Trials Registry, the Cochrane Database of Systematic Reviews, and Embase® from 2011 through December 4, 2017. We included UI outcomes (cure, improvement, satisfaction), quality of life, and adverse events. For UI outcomes, we conducted network meta-analyses, combining direct and indirect comparisons across studies. Quality of life and adverse event outcomes are narratively described.

Results. We identified 233 eligible studies, of which 140 reported on UI outcomes, 96 on quality of life, and 127 on adverse events. Studies evaluated 16 categories of interventions with 53 specific interventions. Fourteen intervention categories have been evaluated for UI outcomes; all except hormones and periurethral bulking agents were more effective to achieve at least one favorable UI outcome than no treatment (variable strength of evidence [SoE]). Among 1st or 2nd line interventions for stress UI, behavioral therapy (BT, alone and in combination with hormones) was more effective than either alpha agonists or hormones to achieve cure or improvement (moderate SoE); alpha agonists were more effective than hormones to achieve improvement (moderate SoE). Among treatments used as 1st or 2nd line interventions for urgency UI, BT was significantly more effective than anticholinergics to achieve cure or improvement (high SoE). Among 3rd line interventions for stress UI, intravesical pressure release, but not periurethral bulking agents, was more effective than no treatment (variable SoE). Neuromodulation, which is commonly used for treatment of urgency UI, is more effective than no treatment of stress UI for cure, improvement, and satisfaction (high SoE). Among studies of women with only stress UI, indirect evidence suggests that intravesical pressure release is more effective to achieve improvement than combination BT and neuromodulation, and triple combination neuromodulation, hormones, and BT may be more effective than either periurethral bulking or combination neuromodulation and BT (all low SoE). Among treatments used as 3rd line interventions for urgency UI, both neuromodulation and onabotulinum toxin A (BTX) are more effective than no treatment (high SoE), and BTX may be more effective than neuromodulation to achieve cure (low SoE). BT, neuromodulation, and anticholinergics resulted in better quality of life than no treatment (low SoE). Urinary tract infections (UTIs) were reported in 11 percent of women receiving transcutaneous electrical nerve stimulation and erosion in 1.6 percent of women with the periurethral bulking agent macroplastique (low SoE). Dry mouth was the most commonly reported adverse event for the anticholinergic oxybutynin (36%) and the alpha agonist duloxetine (13%) (high SoE). BTX was associated with UTIs (36%) and urinary retention (10% to 20%) (moderate SoE). Constitutional adverse events (e.g., nausea, insomnia, fatigue) were common with duloxetine (moderate SoE).

Conclusions. Network meta-analyses demonstrated that most nonpharmacological and pharmacological interventions are more likely than no treatment to improve UI outcomes and quality of life. BT, alone or in combination with other interventions, is generally more effective than 2nd line (pharmacological) therapies alone for both stress and urgency UI. Common adverse events with pharmacological treatments include dry mouth, nausea, and fatigue. BTX is associated with urinary infections and retention. Periurethral bulking agents are associated with erosion and need for surgical removal. Large gaps remain in the literature regarding head-to-head comparisons of individual interventions.
