New Approaches in the Study of the Pathogenesis of Urethral Pain Syndrome

INTRODUCTION

Urethral pain syndrome (UPS) is still a pathology in which the diagnosis is formulated as a "diagnosis of exclusion". The exact pathogenetic mechanisms are not yet fully understood and clear recommendations for the prevention and treatment of UPS are absent.

METHODS AND PARTICIPANTS

A clinical and laboratory evaluation of 55 patients with established UPS included history taking, basic laboratory tests (e.g., complete blood count and clinical urine test), physical examination, uroflowmetry, and cystourethroscopy. Additionally, transvaginal ultrasound (TVUS) with compression elastography and cross-polarization optical tomography (CP OCT) were performed in 24 and 33 patients with UPS, respectively. The control group consisted of 14 patients with no complaints from the urinary system.

RESULTS

TVUS showed an expansion in the diameter of the internal lumen of the urethra, especially in the proximal region compared with the norm. Compression elastography revealed areas with increased stiffness (presence of fibrosis) in urethral and surrounding tissues. The performed CP OCT study showed that in UPS, the structure of the tissues in most cases was changed: trophic alterations in the epithelium (hypertrophy or atrophy) and fibrosis of underlying connective tissue were observed. The proximal fragment of the urethra with UPS underwent changes identical to those of the bladder neck.

CONCLUSION

This paper showed that the introduction of new technology-CP OCT-in conjunction with TVUS will allow verification of structural changes in tissues of the lower urinary tract at the level of their architectonics and will help doctors understand better the basics of the UPS pathogenesis.

A guide for urogynecologic patient care utilizing telemedicine during the COVID-19 pandemic: review of existing evidence

Introduction and hypothesis

The COVID-19 pandemic and the desire to “flatten the curve” of transmission have significantly affected the way providers care for patients. Female Pelvic Medicine and Reconstructive Surgeons (FPMRS) must provide high quality of care through remote access such as telemedicine. No clear guidelines exist on the use of telemedicine in FPMRS. Using expedited literature review methodology, we provide guidance regarding management of common outpatient urogynecology scenarios during the pandemic.

Methods

We grouped FPMRS conditions into those in which virtual management differs from direct in-person visits and conditions in which treatment would emphasize behavioral and conservative counseling but not deviate from current management paradigms. We conducted expedited literature review on four topics (telemedicine in FPMRS, pessary management, urinary tract infections, urinary retention) and addressed four other topics (urinary incontinence, prolapse, fecal incontinence, defecatory dysfunction) based on existing systematic reviews and guidelines. We further compiled expert consensus regarding management of FPMRS patients in the virtual setting, scenarios when in-person visits are necessary, symptoms that should alert providers, and specific considerations for FPMRS patients with suspected or confirmed COVID-19.

Results

Behavioral, medical, and conservative management will be valuable as first-line virtual treatments. Certain situations will require different treatments in the virtual setting while others will require an in-person visit despite the risks of COVID-19 transmission.

Conclusions

We have presented guidance for treating FPMRS conditions via telemedicine based on rapid literature review and expert consensus and presented it in a format that can be actively referenced.

Management of Urinary Tract Infections in Direct to Consumer Telemedicine

BACKGROUND

Urinary tract infections (UTI) are a common reason for seeking care via direct to consumer (DTC) telemedicine, yet patterns of care, including antibiotic prescribing, have not been reported.

OBJECTIVE

To describe management of UTI in a large nationwide DTC telemedicine platform.

DESIGN

Cross-sectional observational study.

PARTICIPANTS

Patients seeking care for or diagnosed with UTI via DTC telemedicine between July 2016 and July 2018.

MAIN MEASURES

Patient measures included age, sex, geographic region, satisfaction with care, and patient-reported call reason. High-risk patients were defined as males, patients over 65 years, or those diagnosed with pyelonephritis. Physician measures included specialty and geographic region. Antibiotic prescription was assessed overall and by antibiotic type. Variation in antibiotic prescriptions was assessed by patient and physician factors, including geographic region of both parties.

KEY RESULTS

Of the 20,600 patients diagnosed with a UTI during the study period, 96% were female. Most (84%) stated their call reason was a UTI. Overall, 94% of UTI patients received an antibiotic; 56% got nitrofurantoin, 29% got trimethoprim-sulfamethoxazole, and 10% got a quinolone. Receipt of an antibiotic was associated with higher satisfaction with care (p < 0.001). While nitrofurantoin was the most common antibiotic for all physician regions, antibiotic type varied by physician region. Of the 6% of the study population defined as high risk, 69% received an antibiotic: 72% of males, 91% of women over 65, and 21% of patients diagnosed with pyelonephritis.

CONCLUSIONS

Management of UTI via DTC telemedicine appears to be appropriate for average-risk patients, and most are able to self-diagnose. Most patients received guideline-concordant care, but over half of high-risk patients received antibiotics. DTC telemedicine offers convenient, low-cost care that is generally appropriate. Efforts should be made to ensure high-risk patients get proper follow-up.

Antibiotic-Resistant E. coli in Uncomplicated Community-Acquired Urinary Tract Infection

BACKGROUND

Routine urine culture testing is not recommended for uncomplicated urinary tract infections (UTIs). As a result, the antibiotic resistance patterns or the organisms causing UTIs are not adequately reflected in routine data. We studied the sensitivity of Escherichia coli (E. coli) to trimethoprim (TMP) and to cotrimoxazole (i.e., trimethoprim/sulfamethoxazole, TMP/SMX) in community-acquired UTI and compared the findings with the resistance data of the Antimicrobial Resistance Surveillance System (ARS).

METHODS

General practitioners and internists in private practice prospectively recruited all of their adult patients with symptoms of a urinary tract infection from May 2015 to February 2016. Urine specimens from all patients were tested (including urine culture testing and antibiotic susceptibility) and infections were defined as uncomplicated or complicated UTIs.

RESULTS

1245 participants from 58 medical practices were enrolled in the study. Pathogenic organisms were found in the urine of 877 patients, of whom 74.5% had E. coli infections. Among the E.-coli-positive UTIs, 52.4% were classified as uncomplicated and 47.6% as complicated. The prevalence of E. coli that was resistant to TMP and to TMP/SMX in uncomplicated UTIs was 15.2% and 13.0%, respectively, compared to 25.3% and 24.4%, respectively, from all UTIs in ARS in 2015. Study participants who had previously taken antibiotics had the highest prevalence of E. coli resistance (30.9%), followed by those who had two or more UTIs within the past six months (28.9%).

CONCLUSION

E. coli with resistance to TMP was significantly less prevalent among the study patients with uncomplicated UTIs than in the routine data of the ARS. Accordingly, TMP should still be considered as an option for the treatment of uncomplicated UTIs. TMP/SMX is considered the agent of second choice because of its side effects. Surveillance systems based on routine data do not yield a representative sample for the evaluation of the resistance situation in patients with uncomplicated UTIs.

Uncomplicated Bacterial Community-Acquired Urinary Tract Infection in Adults

BACKGROUND

Uncomplicated bacterial community-acquired urinary tract infection is among the more common infections in outpatient practice. The resistance level of pathogens has risen markedly. This S3 guideline contains recommendations based on current evidence for the rational use of anti - microbial agents and for the prevention of inappropriate use of certain classes of antibiotics and thus of the resulting drug resistance. The prevention of recurrent urinary tract infection is considered in this guideline for the first time.

METHODS

The guideline was updated under the aegis of the German Urological Society (Deutsche Gesellschaft für Urologie). A systematic literature search (period: 2008-2015) concerning the diagnosis, treatment, and prevention of uncomplicated urinary tract infections was carried out in the Cochrane Library, MEDLINE, and Embase databases. Randomized, controlled trials and systemic reviews were included. Relevant guidelines were identified in a guideline synopsis.

RESULTS

Symptom-oriented diagnostic evaluation is highly valued. For the treatment of cystitis, fosfomycin-trometamol, nitrofurantoin, nitroxolin, pivmecillinam and trimethoprim are all equally recommended. Fluorquinolones and cephalosporins are not recommended. Uncomplicated pyelonephritis with a mild to moderate clinical course ought to be treated with oral cefpodoxime, ceftibuten, ciprofloxacin, or levofloxacin. For acute, uncomplicated cystitis, with mild to moderate symptoms, symptomatic treatment alone may be considered instead of antibiotics after discussion of the options with the patient. Mainly non-antibiotic measures are recommended for prophylaxis against recurrent urinary tract infection.

CONCLUSION

Physicians who treat uncomplicated urinary tract infections should familiarize themselves with the newly revised guideline's recommendations on the selection and dosage of antibiotic treatment so that they can responsibly evaluate and plan antibiotic treatment for their affected patients.

Does clinical examination aid in the diagnosis of urinary tract infections in women? A systematic review and meta-analysis

Background

Clinicians should be aware of the diagnostic values of various symptoms, signs and antecedents. This information is particularly important in primary care settings, where sophisticated diagnostic approaches are not always feasible. The aim of the study is to determine the probability that various symptoms, signs, antecedents and tests predict urinary tract infection (UTI) in women.

Methods

We conducted a systematic search of the MEDLINE and EMBASE databases to identify articles published in all languages through until December 2008. We particularly focused on studies that examined the diagnostic accuracy of at least one symptom, sign or patient antecedent related to the urinary tract. We included studies where urine culture, a gold standard, was preformed by primary care providers on female subjects aged at least 14 years. A meta-analysis of the likelihood ratio was performed to assess variables related to the urinary tract symptoms.

Results

Of the 1, 212 articles identified, 11 met the selection criteria. Dysuria, urgency, nocturia, sexual activity and urgency with dysuria were weak predictors of urinary tract infection, whereas increases in vaginal discharge and suprapubic pain were weak predictors of the absence of infection. Nitrites or leukocytes in the dipstick test are the only findings that clearly favored a diagnosis of UTI.

Conclusions

Clinical findings do not aid in the diagnosis of UTI among women who present with urinary symptoms. Vaginal discharge is a weak indicator of the absence of infection. The urine dipstick test was the most reliable tool for detecting UTI.
