Guidelines for the Prevention, Diagnosis, and Management of Urinary Tract Infections in Pediatrics and Adults A WikiGuidelines Group Consensus Statement

Author/s: 
Zachary Nelson, Abdullah Tarik Aslan, Nathan P. Beahm

Importance Traditional approaches to practice guidelines frequently result in dissociation between strength of recommendation and quality of evidence.

Objective To create a clinical guideline for the diagnosis and management of urinary tract infections that addresses the gap between the evidence and recommendation strength.

Evidence Review This consensus statement and systematic review applied an approach previously established by the WikiGuidelines Group to construct collaborative clinical guidelines. In May 2023, new and existing members were solicited for questions on urinary tract infection prevention, diagnosis, and management. For each topic, literature searches were conducted up until early 2024 in any language. Evidence was reported according to the WikiGuidelines charter: clear recommendations were established only when reproducible, prospective, controlled studies provided hypothesis-confirming evidence. In the absence of such data, clinical reviews were developed discussing the available literature and associated risks and benefits of various approaches.

Findings A total of 54 members representing 12 countries reviewed 914 articles and submitted information relevant to 5 sections: prophylaxis and prevention (7 questions), diagnosis and diagnostic stewardship (7 questions), empirical treatment (3 questions), definitive treatment and antimicrobial stewardship (10 questions), and special populations and genitourinary syndromes (10 questions). Of 37 unique questions, a clear recommendation could be provided for 6 questions. In 3 of the remaining questions, a clear recommendation could only be provided for certain aspects of the question. Clinical reviews were generated for the remaining questions and aspects of questions not meeting criteria for a clear recommendation.

Conclusions and Relevance In this consensus statement that applied the WikiGuidelines method for clinical guideline development, the majority of topics relating to prevention, diagnosis, and treatment of urinary tract infections lack high-quality prospective data and clear recommendations could not be made. Randomized clinical trials are underway to address some of these gaps; however further research is of utmost importance to inform true evidence-based, rather than eminence-based practice.

What Is Prostatitis?

Author/s: 
Rebecca Voelker

Prostatitis involves infection, inflammation, or pain in the prostate gland and affects about 9% of men during their lifetime.

What Is Acute Bacterial Prostatitis?
Acute bacterial prostatitis is a urinary tract infection that involves the prostate.1 Patients with acute prostatitis typically have fever, chills, pelvic pain, sudden onset of frequent urination, and pain or burning during urination. Some patients cannot empty their bladder adequately (urinary retention).

Risk factors include medical procedures such as cystoscopy, urethral catheterization, prostate biopsy, urinary obstruction such as benign prostatic hyperplasia and strictures, anal intercourse without condom use, immunosuppression, and certain neurological disorders such as multiple sclerosis, stroke, and spinal cord injury. Digital rectal examination often reveals prostate swelling and tenderness. The diagnosis of acute bacterial prostatitis is made based on symptoms, urinalysis, and urine culture. First-line treatment is 2 to 4 weeks of antibiotics. Men with urinary retention due to a swollen prostate should have a urinary catheter placed to relieve discomfort and to drain the infected urine.

What Is Chronic Bacterial Prostatitis?
Chronic bacterial prostatitis is a persistent bacterial infection of the prostate despite antibiotic therapy. Patients typically do not have fever or chills, and between episodes of infection they may have no symptoms or have persistent pelvic pain and/or lower urinary tract symptoms.

Risk factors include age 50 years or older, prior acute bacterial prostatitis, urethral surgery or catheterization, anal intercourse without condom use, and genitourinary tuberculosis. The diagnosis is made when multiple urine culture samples grow the same bacterial strain during episodes of urinary tract infection. First-line treatment for chronic bacterial prostatitis is at least 4 weeks of oral antibiotics such as ciprofloxacin or levofloxacin.

Prostatitis: A Review

Author/s: 
Benjamin J Borgert, Eric M Wallen, Minh N Pham

Importance Prostatitis is defined as infection, inflammation, or pain of the prostate gland and affects approximately 9.3% of men in their lifetime.

Observations Acute bacterial prostatitis consists of a urinary tract infection (UTI) that includes infection of the prostate, typically associated with fever or chills and caused by gram-negative bacteria, such as Escherichia coli, Klebsiella, or Pseudomonas, in 80% to 97% of cases. First-line therapy for acute prostatitis is broad-spectrum intravenous or oral antibiotics, such as intravenous piperacillin-tazobactam, ceftriaxone, or oral ciprofloxacin, which has a 92% to 97% success rate when prescribed for 2 to 4 weeks for people with febrile UTI and acute prostatitis. Chronic bacterial prostatitis is defined as a persistent bacterial infection of the prostate, typically presenting as recurrent UTIs from the same strain. Up to 74% of chronic bacterial prostatitis diagnoses are due to gram-negative organisms, such as E coli. First-line therapy for chronic bacterial prostatitis is a minimum 4-week course of levofloxacin or ciprofloxacin. Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) presents as pelvic pain or discomfort for at least 3 months and is associated with urinary symptoms, such as urinary frequency. CP/CPPS is diagnosed when evaluation, including history and physical examination, urine culture, and postvoid residual measurement, does not identify other causes for the symptoms, such as infection, cancer, urinary obstruction, or urinary retention. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) measures symptom severity (scale of 0-43), with a 6-point change considered clinically meaningful. First-line oral therapy for CP/CPPS with urinary symptoms is α-blockers (eg, tamsulosin, alfuzosin; ΔNIH-CPSI score difference vs placebo = −10.8 to −4.8). Other oral therapies are associated with modest changes in NIH-CPSI score compared with placebo, including anti-inflammatory drugs (eg, ibuprofen; ΔNIH-CPSI score difference = −2.5 to −1.7), pregabalin (ΔNIH-CPSI score difference = −2.4), and pollen extract (ΔNIH-CPSI score difference = −2.49).

Conclusions and Relevance Prostatitis includes acute bacterial prostatitis, chronic bacterial prostatitis, and CP/CPPS, each of which is diagnosed and treated differently. First-line treatments are broad-spectrum antibiotics for acute bacterial prostatitis (such as piperacillin-tazobactam, ceftriaxone, or ciprofloxacin), at least 4 weeks of fluoroquinolones for chronic bacterial prostatitis, and α-blockers for CP/CPPS with urinary symptoms.

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.

Effect of 7 vs 14 Days of Antibiotic Therapy on Resolution of Symptoms Among Afebrile Men With Urinary Tract Infection: A Randomized Clinical Trial

Author/s: 
Drekonja, D. M., Trautner, B., Amundson, C.

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.
