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).

設(shè)備易損壞(輸尿管鏡的耐用性評價(jià)報(bào)告規(guī)模是3--159次，使用壽命差距較大)，修理本錢高(輸尿管鏡損壞后一般都需要大修，一次的費(fèi)用3萬以上)，所以如何提高軟鏡的使用壽命成為許多醫(yī)院領(lǐng)導(dǎo)頭疼事情。

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.

一般醫(yī)院領(lǐng)導(dǎo)和行政科室以為設(shè)備的損壞都是由于臨床醫(yī)師的使用問題，把醫(yī)師的技術(shù)水平和操作能力作為主要原因進(jìn)行追責(zé)甚要求醫(yī)師和科室承擔(dān)修理費(fèi)用。

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.
             

其實(shí)，導(dǎo)致輸尿管鏡損傷的原因有許多，有研究標(biāo)明，醫(yī)師操作要素占32%，不標(biāo)準(zhǔn)要素68%。

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.

關(guān)于纖維輸尿管鏡的損壞各廠家的產(chǎn)品不同不大，臨床醫(yī)師操作原因?qū)е碌能涚R的損壞占28%，進(jìn)一步的標(biāo)準(zhǔn)操作使術(shù)中對軟鏡的損壞持續(xù)減少;非手術(shù)原因?qū)е碌脑O(shè)備損壞占72%，其中尤其重要的是水洗、預(yù)清洗和過程的損壞占比十分高。

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.
