Ureteroscopy is now the primary instrument for the treatment of upper urinary tract stones. Because of its high safety, short learning curve and low risk of operation, it is loved by doctors and patients. However, the purchase price of ureteroscope is expensive (the price of flexible fiberscope is more than 200000, and the price of electronic flexible ureteroscope is more than 400000).
The equipment is easy to be damaged (the scale of the durability evaluation report of ureteroscope is 3-159 times, the service life gap is large), and the repair cost is high (after the ureteroscope is damaged, it generally needs to be overhauled, and the cost is more than 30000 at a time), so how to improve the service life of flexible ureteroscope has become a headache for many hospital leaders.
Generally, hospital leaders and administrative departments think that the damage of equipment is due to the use of clinicians, and take the technical level and operation ability of doctors as the main reason for accountability, and even require doctors and departments to bear the repair costs.
In fact, there are many reasons leading to ureteroscopic injury. Studies have shown that 32% of the patients are doctors' operation factors, and 68% of the patients are non-standard sterilization factors.
The damage of flexible ureteroscope caused by clinician's operation accounted for 28%, and the further standard operation reduced the damage of flexible ureteroscope during operation; the damage of equipment caused by non-surgical reasons accounted for 72%, especially the damage of washing, pre cleaning and sterilization process.
