Flexible cystoscopy findings in patients investigated for profound lower urinary tract symptoms, recurrent urinary tract infection, and pain

New avenue of diagnostic stewardship: procedural stewardship for recurrent urinary tract infections in female patients

Introduction

Societal guidelines offer a weak recommendation to perform cystoscopy for female patients with recurrent urinary tract infections (rUTI) of advanced age and/or with high-risk features. These guidelines lack the support of robust data and are instead based on expert opinion. In this retrospective cohort study, we aim to determine the utility of cystoscopy in patients with and without high-risk features for rUTI.

Materials and methods

We identified 476 women who underwent cystoscopy for the evaluation of rUTI at a single tertiary academic medical center from May 1, 2015 and March 15, 2021. Patients were excluded if they had a competing indication for cystoscopy. Risk factors, demographic information, cystoscopic findings, and patient outcomes were analyzed.

Results

192 (41.1%) were classified as having complicated UTI. We identified six patients (1.3%) with findings that prompted management to significantly impact patient outcomes. All six patients had high-risk features. 14 patients (3.0%) were found to have mucosal abnormalities prompting biopsy, three of which required general anesthesia. All 14 biopsies were ultimately benign.

Conclusions

Our findings demonstrate a low diagnostic yield and increased risk exposure for women undergoing cystoscopy for the evaluation of complicated rUTI. Additionally, our observations support prior studies indicating that cystoscopy has limited utility in the evaluation of rUTI without high-risk features.

Diagnostic and therapeutic cystoscopy in bladder pain syndrome/interstitial cystitis: systematic review of literature and consensus on methodology

INTRODUCTION AND HYPOTHESIS

Cystoscopy has been routinely performed in patients suspected to be suffering from bladder pain syndrome/interstitial cystitis (BPS/IC) across the globe. The methodology reported by various guidelines appears to have differences in the techniques and hence there is a need for a review of all those techniques in order to arrive at a consensus. The aim was to review the literature describing the prevalent techniques of cystoscopy for patients of BPS/IC and try to evolve a consensus.

METHODS

The group the Global Interstitial Cystitis, Bladder Pain Society (GIBS) has worked collectively to systematically review the literature using the key words, "Cystoscopy in Hunner's lesions, bladder pain syndrome, painful bladder syndrome and interstitial cystitis" in the PubMed, COCHRANE, and SCOPUS databases. A total of 3,857 abstracts were studied and 96 articles referring to some part of technique of cystoscopy were short-listed for review as full-length articles. Finally, six articles with a description of a technique of cystoscopy were included for final tabulation and comparison. The group went on to arrive at a consensus for a stepwise technique of diagnostic and therapeutic cystoscopy in cases of BPS/IC. This technique has been compared with the previously described techniques and may serve to be a useful practical guide for treating physicians.

CONCLUSION

It is important to have a uniform standardized technique for performing a diagnostic and therapeutic cystoscopy in patients with BPS/IC. Consensus on one such a technique has been arrived at and described in the present article.

Comparison of the diagnostic yield of routine versus indicated flowmetry, ultrasound and cystoscopy in women with recurrent urinary tract infections

Introduction and hypothesis

To quantify and compare the outcomes of routine vs. urologist-requested diagnostic testing for recurrent urinary tract infections (rUTI).

Methods

A retrospective cohort study of patients with rUTI referred to a large non-academic teaching hospital between 2016 and 2018 (Hospital A) and a university hospital between 2014 and 2016 (Hospital B). Electronic medical records were reviewed for baseline and diagnostic data. Women underwent the following assessments routinely: urinalysis, voiding diary, flowmetry in Hospital A and urinalysis, voiding diary, flowmetry, ultrasound, abdominal x-ray and cystoscopy in Hospital B. All other diagnostics were performed by indication in each hospital.

Results

We included 295 women from Hospital A and 298 from Hospital B, among whom the mean age (57.6 years) and mean UTI frequency (5.6/year) were comparable, though more were postmenopausal in Hospital A. We identified abnormalities by flowmetry or post-void residual volumes in 134 patients (Hospital A: 79; Hospital B: 55), cystoscopy in 14 patients (Hospital A: 6; Hospital B: 8) and ultrasound in 42 patients (Hospital A: 16; Hospital B: 26), but these differences were not significant. Diagnostics altered treatment in 117 patients (e.g., pelvic floor muscle training, referral to another specialist, surgical intervention), mostly due to flowmetry and post-void residual volume measurement. The retrospective design and absence of follow-up data limit these results.

Conclusions

The routine use of cystoscopy and ultrasound in female patients with rUTIs should not be recommended as they yield few abnormalities and lead to additional costs.

Guideline-based flexible cystoscopy safely improves capacity, avoiding unnecessary intervention with cost savings

Introduction:

Flexible cystoscopy (FC) is a common and useful diagnostic tool. Because of its broader applications, availability and simplicity, there has been criticism of its overuse with accompanying financial burden to the health system and unnecessary invasive intervention to the patient. Therefore, we reviewed our local practice against current guidelines to evaluate compliance, enhance patient safety and capacity utilisation.

Patients and methodology:

Data were collected retrospectively on all patients having FC over two months. The indications and findings of FC were gathered from the hospital electronic patient record system.

Results:

A total of 413 FCs were carried out over the study period. The most common indications were cancer surveillance 116 (28%) and visible haematuria 76 (18.4%). A total of 152 (37%) FCs were performed for non-recommended indications. The most common conditions that deviated from guidelines were lower urinary tract symptoms (LUTS) (72, 17.4%), urinary tract infection (UTI) (41, 9.9%) and asymptomatic non-visible haematuria (35, 8.5%). In all non-visible haematuria cases, 65 (90%) of LUTS and 39 (95%) of UTI patients, FC was non-contributory. Adherence to guidelines would have yielded 37% of FC slots. Based on current UK National Tariffs, cost savings would have been £352,032 annually in this trust.

Conclusions:

FC is a frequent investigation within urology departments for which referral guidelines exist. Protocol-driven practice enables appropriate use, ensures patient safety and leads to efficient utilisation of capacity with substantial cost savings.

Level of evidence:

Not applicable for this multicentre audit.

Closing the Gender Gap: Can We Improve Bladder Cancer Survival in Women? - A Systematic Review of Diagnosis, Treatment and Outcomes

INTRODUCTION

Despite recent attention, there are no gender specific guidelines to address the disparity in bladder cancer survival between the sexes. The focus of this review was to identify areas of clinical practice that may influence bladder cancer outcomes and to provide evidence-based recommendations to improve bladder cancer survival in women.

METHOD

A systematic search of MEDLINE was conducted to identify studies related to referral, diagnosis, treatment and outcomes of patients with bladder cancer with particular reference to gender differences.

RESULTS

Patients' knowledge of key signs and symptoms of bladder cancer is poor. There is evidence that there is a gender difference in referral patterns both at patient and primary care level. The presence of cystits, in particular, delays referral. Treatment and surveillance of high-risk non-muscle invasive cancers is variable and non-urothelial bladder cancer, which has higher incidence in women is more likely to be treated non-operatively than urothelial bladder cancer.

CONCLUSION

We have offered recommendations to improve patient education and streamline referrals and suggested considerations for treatment of high-risk cancers to help improve survival in female bladder cancer patients.

Investigation of uncomplicated recurrent urinary tract infections in women

Background:

Recurrent urinary tract infections (UTIs) in women are common despite anatomically normal urinary tracts and are frequently referred to secondary care for further assessment.

Patients and methods:

Clinic letters and pathology reports of 244 women referred to our centre over a 2-year period with uncomplicated recurrent UTIs were reviewed to determine the investigations they underwent in both primary and secondary care.

Results:

A significant proportion of women do not meet the criteria for recurrent UTIs as their infections are not proven on culture. The majority of women undergo both renal tract ultrasound scan (USS) and flexible cystoscopy. Though USS was found to demonstrate relevant pathology, flexible cystoscopy, however, did not reveal any relevant pathology.

Conclusion:

Investigation of women with recurrent uncomplicated UTIs should be done with adequate cultures and renal tract USS.
