Market readiness for single-use cystoscopes


Cystoscopy is one of the most common procedures in urology practices, and is considered safe. Both rigid and flexible cystoscopes can be used for cystoscopy procedures. Flexible cystoscopes are used for diagnostics, treatment, and control of both malignant and benign disorders of the lower urinary tract and are often utilized in outpatient clinics. However, reusable flexible cystoscopes are often subject to delays or cancellation of cystoscopy procedures as cystoscopes become unavailable when out for reprocessing or repairs.1–4 Moreover, reusable cystoscopes are typically associated with costly and labor-intensive reprocessing, high repair costs,1,3,5–7 and risk of cystoscopy-related transmission of pathogens.8–10 For this reason, single-use cystoscopes have been subject to increased awareness, with single-use flexible cystoscopes such as the Ambu® aScope 4 Cysto recently entering the market. The sterile single-use flexible cystoscope offers consistent quality with no need for reprocessing or repairs, and no risk of cross-contamination as the cystoscope is disposed of after each procedure. Single-use flexible ureteroscopes are already widely adopted within urology practices; however, the market readiness for the recently introduced single-use flexible cystoscopes remains unknown. Thus, this study investigates the worldwide market readiness for single-use flexible cystoscopes among urologists and procurement managers (PMs) from Europe, Japan, and the US. Our goal is to help inform decision-makers about the advantages associated with single-use cystosopes and create transparency about the receptiveness of single-use cystoscopes within urology practices.

Materials and Methods


An online survey using QuestionPro® was distributed to urologists and PMs in France, Germany, Italy, Japan, Spain, the UK, and the US between March 10, 2020 and July 14, 2020. A third-party consultancy firm identified and contacted all respondents and assigned them compensation for replying to the survey, keeping the sender anonymous. The third-party consultancy firm were also responsible for obtaining informed consent from all respondents. All surveys were translated into the respective local language.


Respondents were excluded from the survey if they did not fall into the category of either a physician performing cystoscopies or a PM covering a urology department. The survey asked respondents to indicate how many of their cystoscopy procedures they would consider using a single-use cystoscope for. They were also asked demographic questions regarding their main setting of employment (eg hospital, clinic), the annual volume of cystoscopy procedures in their department, their gender, their role (if any) on value analysis committees, their department’s current reprocessing setup, the cystoscope currently used by their department, and whether they currently use single-use ureteroscopes. Regarding current experiences with reusable cystoscopes, the survey included questions on the respondents’ perceived contamination rate of cystoscopes and the related infection risk, as well as issues with availability and experienced loss of image quality or lack of appropriate maneuverability. The full survey can be found in Appendix 1.

Statistical Methods

All statistical analyses were performed using the standard software package Stata/SE version 16.1, StataCorp. Fisher’s exact test was used to analyze the categorical variables and simple linear regression was applied to the continuous variables, with statistical significance considered at p<0.05.


In the legislation at § 14, stk. 2 it says regarding research projects using questionnaires, that such research should only be submitted for ethical approval if the research project involves human biological material.11 Our study did not involve any data from human subjects, thus no International Review Board (IRB) review and approval was required. The study was performed in accordance with the Declaration of Helsinki and written informed consent was obtained from participants.


A total of 415 urologists and PMs completed the survey, of whom 343 (82.7%) were urologists and 72 (17.3%) were PMs. Of the 415 urologists, 245 (59.0%) were from European countries, seventy (16.9%) were from Japan and 100 (24.1%) were from the US. Among respondents from European countries, 45 were from Italy and 200 were evenly distributed between France, Germany, Spain, and the UK. Table 1 shows the country of origin and the occupation of the respondents. A total of 863 (87.5%) of respondents were male 363 and 52 (12.5%) were female. In addition, 178 (42.9%) respondents were part of their institution’s value analysis committee. Among the urologists, 278 (81%) specified their number of years’ experience performing cystoscopies. A total of 182 (65.5%) had 10 years of experience, 57 (20.5%) had <1–7 years and 39 (14.0%) had 7–10 years (Figure 1).

The respondents were asked about the endoscopy cleaning process currently in use in their urology department. A total of 129 (38.0%) used high-level disinfection (HLD), 116 (34.1%) used sterilization, 83 (24.4%) used chemical baths, and 12 (3.5%) used Tristel wipes™ (Tristel Solutions Ltd., USA) as the primary cleaning process. When asked about their reprocessing setup, 227 (56.2%) used local cleaning, 166 (41.1%) used central cleaning, and 11 (2.7%) used external cleaning (see Figure 2).

Regarding current experiences with reusable cystoscopes, 221 (53.3%) indicated concern regarding cystoscopy-related infections as a result of using contaminated cystoscopes, and 276 (69.0%) had experienced lost image quality or a lack of appropriate maneuverability of reusable cystoscopes. Finally, 213 (51.5%) had used single-use ureteroscopes in their urology department.

Significant differences in certain parameters were discovered between regions. On average, the respondents’ oldest cystoscope in use was 6.2 years old. Amongst German respondents the oldest cystoscope in use was 7.6 years on average. On the other hand, the oldest cystoscope in use was 4.3 years on average amongst Japanese respondents. When looking at all European countries, the oldest cystoscope was on average 6.8 years and thereby significantly older than the oldest cystoscope in use reported by Japanese respondents (p<0.001). The oldest cystoscope in use among American respondents was on average 1.7 years older compared to that of Japanese respondents (p=0.014). Figure 3 illustrates the average age of the oldest cystoscope in use in each country compared to the overall average.

Figure 3 Oldest cystoscope (average) in use for each country.

All respondents reported a conversion rate by anticipating the number of cystoscopy procedures, in percentage terms, for which they would consider using a single-use cystoscope. On average, the respondents indicated that they would consider converting to single-use in 44.5% of their cystoscopy procedures. Italian respondents reported the highest average conversion rate, at 57.5% of their procedures, while Japanese respondents reported the lowest average conversion rate, at 23.7%. German respondents—who had been found to have the oldest cystoscopes in use—reported a significantly higher conversion rate compared to Japanese respondents, who had the youngest cystoscopes in use (p<0.001). Figure 4 shows the average stated conversion rate for each country.

Several factors revealed differences in conversion rates (see Table 2). Respondents whose department used external cleaning reported a higher conversion rate on average, as did respondents who often had to wait for a cystoscope to become available. However, the difference was not significant. Respondents who were part of their institution’s value committee were more likely to indicate a higher anticipated conversion rate (48.3% vs 41.6%, p=0.044). Likewise, respondents who used single-use ureteroscopes in their department, and respondents who indicated concern about cystoscopy-related infections as a result of using contaminated cystoscopes, were also more likely to indicate a higher anticipated conversion rate compared to those who did not use single-use ureteroscopes or did not express such concern (50.5% vs 42.2%, p=0.010 and 50.5% vs 37.7%, p<0.001, respectively). Finally, respondents who indicated that cost transparency is important when purchasing cystoscopes were more likely to indicate a higher anticipated conversion rate compared to respondents who felt cost-transparency to be moderately or not important (56.2% vs 42.3%, p=0.002).

To our knowledge, this study is the first to investigate market readiness for single-use cystoscopes according to urologists and PMs worldwide. Over a decade ago, the world’s first single-use flexible bronchoscope was launched by Ambu A/S. Since then, single-use endoscopes have entered several endoscopy areas, including urology where single-use ureteroscopes are widely used today. With benefits such as cost-savings,12,13 as well as elimination of the risk of cross-contamination and need for frequent repair, single-use ureteroscopes are now widely adopted, whereas single-use cystoscopes have only recently been introduced.

In this study, we measured urologists’ and PMs’ willingness to adopt single-use cystoscopes, according to the respondents’ anticipated number of procedures for which they would consider converting to single-use, as an indicator of the market readiness for single-use cystoscopes. The results indicate that urologists and PMs are willing to convert nearly half (44.5%) of their procedures to single-use cystoscopes on average. Factors affecting the respondents’ anticipated conversion rate were identified using Fisher’s exact test and simple linear regression.

Respondents’ indication of willingness to convert nearly half of their procedures to single-use cystoscopes was obtained without their having experienced the performance of a single-use cystoscopes for different procedures. Therefore, this assessment is based solely on a description of…
