Cystoscopy; a BMJ overview and advantages of Endosheath Technology
Overcoming drawbacks presented by standard flexible endoscopes:
BMJ 2014;348:g2047. This article addresses the problems of infection presented by standard endoscopes and recommends  sheaths with working channels as a solution. Endosheath Technology overcomes the drawbacks presented by standard flexible endoscopes as described in the BMJ article.
The drawbacks that were overcome included: the capital cost of multiple endoscopes required for several patients on a list, the damages caused to flexible endoscopes requiring frequent processing, the expense and time required to reprocess endoscope, the risks to personnel and the environment posed by toxic chemicals the difficulty of ensuring that, particularly working channels, are free of contamination
The solution offered by the Endosheath with a PrimeSight endoscope  is elegant:

Flexible endoscopes without working channels are fitted with sterile disposable sheaths incorporating the working channels.
A prescribed  2 minute protocol ensures that asepsis is maintained and patients are in contact only with sterile surfaces of the sheath.
What is EndoSheath® Technology?
The Vision Sciences® endoscope has no working channel, instead it is fitted with a sterile disposable sheath containing the working channel.
The sheath covers the endoscope and completely isolates the endoscope from patient contact. How does EndoSheath® Technology work?
Prior to each procedure the endoscope is placed inside a new sterile sheath following an aseptic protocol. After the procedure the sheath is removed from the endoscope and discarded. The sheath eliminates the need for toxic high-level disinfection routines between each patient. The result is a safe, sterile instrument for each patient and rapid equipment turnaround for the practice.
What does this mean for the clinic? Only one scope is needed for a full list. The aseptic procedure for fitting the sterile sheath then removing it takes just 5-10 minutes. Time to clean scopes and process them through a washer disinfector is saved. Staff is not exposed to toxic disinfection chemicals. What does this mean for the patients?
The patients are in contact only with a sterile sheath. The risk of infection caused by contaminated working channel is eliminated .
What does this mean for the budget?
Fewer endoscopes are needed – so much lower capital expenditure. Cost of washer disinfectors and their maintenance is eliminated. Less handling of the endoscope results in less frequent need for repairs
