Abstract
OBJECTIVE To compare clinical outcomes of single-use endoscopes with those of reusable endoscopes to better define their role within urology. METHODS A systematic search of electronic databases was performed. All studies comparing the clinical outcomes of participants undergoing urological procedures with single-use endoscopes to those of participants treated with reusable endoscopes were included. Results are reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement. RESULTS Twenty-one studies in 3943 participants were identified. Six different single-use flexible ureteroscopes and two different single-use flexible cystoscopes were assessed. There were no differences in mean postoperative infection rates (4.0% vs 4.4%; P = 0.87) or overall complication rates (11.5% vs 11.9%; P = 0.88) between single-use and reusable endoscopes. For patients undergoing flexible ureteroscopy there were no differences in operating time (mean difference -0.05 min; P = 0.96), length of hospital stay (LOS; mean difference 0.06 days; P = 0.18) or stone-free rate (SFR; 74% vs 74.3%; P = 0.54) between the single-use and reusable flexible ureteroscope groups. CONCLUSION This study is the largest to compare the clinical outcomes of single-use endoscopes to those of reusable endoscopes within urology, and demonstrated no difference in LOS, complication rate or SFR, with a shorter operating time associated with single-use flexible cystoscope use. It also highlights that the cost efficiency and environmental impact of single-use endoscopes is largely dependent on the caseload and reprocessing facilities available within a given institution. Urologists can therefore feel confident that whether they choose to 'use' or to 'reuse' based on the financial and environmental implications, they can do so without negatively impacting patient outcomes.

Single-Use Ureteroscopy and Environmental Footprint: Review of Current Evidence. Curr Urol Rep 2023; 24:281-285.

Abstract
PURPOSE OF REVIEW Ureteroscopy is a well-established treatment modality for kidney and ureteric calculi in addition to playing a key role in upper tract cancer diagnostics. Traditional reusable flexible ureteroscopes are technologically advanced and expensive pieces of equipment that require repeat sterilisation and periodical repair. These issues have led to the development of single-use flexible ureteroscopes that are disposed of after each case. Whilst this may be advantageous in many respects, the environmental impact of such technology is yet to be fully determined. The aim of this review is to therefore identify and summarise the available literature concerning the environmental footprint of single-use ureteroscopy. RECENT FINDINGS To identify the latest research on this topic, a systematic search of world literature was conducted using the Medline, Embase, and PsycINFO databases. PRISMA guidelines were followed and articles were assessed by all authors and relevant study results were included in a narrative format. Only one relevant article was identified and included. This study found that a single-use flexible ureteroscope (LithoVueTM by Boston Scientific) generated an equivalent amount of carbon dioxide per case to a contemporary reusable flexible ureteroscope. Literature concerning the environmental footprint of single-use ureteroscopy is worryingly lacking. No conclusions can be definitively drawn from a single study and further research is imperative given the global climate crisis and the significant contribution that healthcare services have to the environmental problem.

Abstract
Flexible ureteroscopy is a well-established method for treatment of urinary stones but flexible ureteroscopes are expensive and fragile devices with a very limited lifetime. Since 2006 with the advent of digital flexible ureteroscopes a great evolution has occurred. The first single-use flexible ureteroscope was launched in 2011 and new models are coming to the market. The aim of this article is to review the characteristics of these devices, compare their results with the reusable devices and evaluate the cost-benefits of adopting single-use flexible ureteroscopes in developing countries.

Abstract
INTRODUCTION Sate of the art on the indications, methods of implementation and medico-economic considerations of reusable flexible ureteroscopes (URSr) vs single use (URSuu)? METHOD Review of the literature (Pubmed) on reusable and single-use ureteroscopes, as well as on the expertise of our center. A PubMed search and narrative review of the data was performed in July 2021. Only articles in French or English were selected. RESULTS The URSr and URSuu have similar technical characteristics and are suitable for the exploration of the upper urinary excretory tract: treatment of stones of the kidney <2cm or of the ureter. The URSr is the most common type of ureteroscope. URSuu are newer and associated with many advantages: no sterilization procedure, immediate availability of equipment in the operating room, reduced waste production at the institutional level. A hybrid use of URSr and URSuu currently seems to be the best compromise from a medico-economic point of view for high volume centers. In the case of a smaller activity or a secondary site, URSuu are more advantageous and the reduction in purchasing costs should accentuate this benefit. CONCLUSION URSr and URSuu are technically similar and allow identical treatment of upper urinary tract pathologies. Their complementary use optimizes the care of urology patients. The barrier to the exclusive use of URSuu remains their cost.

Miniaturized percutaneous nephrolithotomy versus retrograde intrarenal surgery in the treatment of lower pole renal stones. Prog Urol 2021; 32:77-84. [PMID: 34332831 DOI: 10.1016/j.purol.2021.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 06/30/2021] [Accepted: 07/06/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES Miniaturization of percutaneous nephrolithotomy techniques have led to their increased consideration for lower pole renal stones that can prove more challenging to reach using retrograde intrarenal surgery. The objectives of the present study were to evaluate and compare the outcomes of miniaturized percutaneous nephrolithotomy (miniPCNL) and retrograde intrarenal surgery (RIRS) for the treatment of lower pole renal stones. MATERIALS AND METHODS A retrospective study was performed in two academic urology departments between January 2016 and June 2019. Patients presenting with one or multiple stones of the lower calyx and/or renal pelvis, between 10 and 40mm based on CT-scan treated by miniPCNL or RIRS were included. RESULTS In all, 115 miniPCNL and 118 RIRS procedures were included. The rate of patients with no significant residual fragment (stone free rate) after the first procedure was higher in the miniPCNL group (69% vs. 52% P=0.01), especially for stones>20mm (63% vs. 24% respectively, P<0.001) and stones with a density≥1000HU (69% vs. 42% respectively, P=0.009). The higher stone free rate of miniPCNL was confirmed in multivariate analysis, adjusting for stone size and number of stones, OR 4.02 (95% CI 2.08-8.11, P<0.0001). The overall postoperative complication rate was higher in the miniPCNL group than in the RIRS group (23% vs. 11%, P=0.01). A second intervention for the treatment of residual fragments was necessary for 9.6% of patients in the miniPCNL group versus 30.5% of patients in the RIRS group (P<0.001). Pre-stenting rate and duration of ureteral drainage (2 [1-8] vs. 25 days [7-37], P<0.001) were lower in the miniPCNL group. CONCLUSIONS The stone free rate was higher after miniPCNL, especially for stones>20mm and with a density>1000 HU, but was associated with a higher risk of postoperative complications and a longer hospital stay. RIRS resulted in fewer complications at the cost of a higher retreatment rate and longer ureteral stenting. LEVEL OF EVIDENCE 3.
