“…Seyam et al conducted a 32 month study to evaluate the use of Isiris α™ single-use cystoscope for ureteric stent retrieval as an off-label for bladder cancer detection. 19 A total of 608 and 603 procedures were performed using Storz flexible video cystoscopes and Isiris α™ integrated stent grasper, respectively. The study concluded that Isiris α™ was comparable to reusable flexible cystoscopes in detection of bladder cancer.…”

Background and ObjectiveAmbu® aScope™ 4 Cysto is a single-use disposable flexible cystoscope that allows clinicians to perform the procedure at any time and any place. It simplifies workflow, frees up resources and allows clinicians to treat more patients. Our trust became the first in the UK and Europe to utilise these cystoscopes. An in-depth evaluation was performed to test its practicality, cost analysis and patient satisfaction against traditional reusable flexible cystoscopes. Material and MethodsWe compared the cost of using Ambu® aScope™ 4 Cysto to perform flexible cystoscopies in 20 patients prospectively against traditional flexible cystoscopes in 20 patients retrospectively. The cost of the equip-ment, reprocessing, cleaning supplies and maintenance were consulted from relevant departments and companies. All prospective patients were also given a patient satisfaction questionnaire to complete. An unpaired t-test was used to analyse the data. ResultsOur study revealed that it costs £135.23 and £166.33 on average to perform a flexible cystoscopy using Ambu® aScope™ 4 Cysto and the traditional flexible cystoscopes, respectively. Our patient survey revealed that there was a statistical significance between the patient experience using the single-use disposable scopes compared with the traditional reusable flexible cystoscopes (P = 0.0455). Further, 95% of patients also preferred a single-use disposable cystoscope over traditional reusable ones, given the option. ConclusionSingle-use disposable flexible cystoscopes are a safe and cost-efficient method of performing the procedure. It is portable and proves to be a simple, efficient and practical way of performing a flexible cystoscopy in an inpatient, outpatient, or emergency setting.

“…For example, the resolution of the B-mode ultrasound is low, and the cystoscope will cause damage to the patient. CT is insufficient in the detection of small lesions, with staging accuracy of about 64%-92% [9][10][11], and CT examination has high radiation. Compared with conventional CT, helical enhanced CT can better display the size, number, and lesions of the tumor, as well as the infiltration of the tumor to some extent.…”

Objective. This study was aimed to explore the accuracy of multi-slice spiral computed tomography (CT) scan in preoperative staging diagnosis of bladder cancer based on hybrid iterative reconstruction algorithm, so as to provide a more reasonable supporting basis for guiding clinical work in the future. Methods. Retrospectively, 120 patients admitted to hospital from July 2019 to April 2021, who were confirmed to be with urothelial carcinoma of the bladder by pathological examination after surgical treatment, were selected. CT images before processing were set as the control group and those after processing were set as the observation group according to whether they were processed by the hybrid iterative algorithm. Postoperative pathological examination was utilized as the standard for analysis. The accuracy and consistency of the two methods were compared. Results. The accuracy of the results of each stage of the observation group (T1 stage: 91.09%, T2 stage: 89.66%, T3 stage: 88.89%, and T4 stage: 88.89%) and consistency (T1 stage: 0.66, T2 stage: 0.69, T3 stage: 0.71, and T4 stage: 0.82) were higher than those of the control group (accuracy: T1—57.01%, T2—48.28%, T3—44.44%, and T4—44.44%). The consistency was as follows: T1—0.32, T2—0.24, T3—0.37, and T4—0.43, and the comparison was statistically significant ( P < 0.05). Conclusion. The adoption value of the image features based on the hybrid iterative reconstruction algorithm in the diagnosis of bladder cancer staging was higher than that of the conventional multi-slice spiral CT, indicating that the hybrid iterative reconstruction algorithm had a good adoption prospect in clinical examination.

BackgroundLittle data exists on the use of disposable or single-use cystoscopy in the outpatient setting. This study aims to evaluate the specs of a single-use cystoscope and review available literature on disposable cystoscopy. Materials and MethodsThe Ambu a Scope 4 (Columbia, MD, USA) is a single-use system that underwent through benchtop evaluation as part of this study. The primary endpoint of the study included prospective benchtop evaluation to establish cystoscope specs, maneuverability, and deflection. Additionally, a PubMed, Google Scholar, MEDLINE, and Embase search was performed using keywords 'cystoscopy AND disposable'; 'cystoscope AND disposable'; 'scope AND disposable'; 'single-use AND cystoscope'. ResultsBenchtop testing was performed on 10 single-use cystoscopes and revealed the Ambu a Scope 4 to have consistent deflection capability in all 10 scopes 210 up/120 down. Additionally, the visualization was rated on a scale of 1-5 based on user impression with all 10 scopes having similar visualization levels of 5.0. The average cord length was 389.9mm, average outer diameter of the scope was 16.2 French and average working channel diameter 6.6 French. Additionally, ten articles were reviewed and included in this study as part of the review on disposable cystoscopy. ConclusionThis paper has described disposable cystoscopy with particular attention to the Ambu a Scope 4. Disposable cystoscopes are becoming more and more available and could become particularly useful in the COVID-19 era. Disposable cystoscopes are a viable option for office-based cystoscopy. These disposable cystoscopes warrant future prospective studies to evaluate their cost, safety, clinician interpretation, patient satisfaction and clinical efficacy.
