Background technology
Most commonly seen in calculi in urinary system be also the most critical is ureteral calculi, and ureteral calculi causes patient acute
Strong angina, and its obstruction can lead to homonymy nephredema (urine), the severe sense of the threat to life such as concurrent pyonephrosis of some patientss
Dye, or cause Ipsilateral kidney due to renal plevis hypertonia atrophy to nonfunctional.Ureter stone operation goldstandard is through urine at present
Road ureteroscope laser/pneumatic ballistic lithotripsy stone-extraction operation (URL).Calculus is smashed by laser or Pneumatic Lithotripsy, and with foreign matter
It clamps multi-pass operation and takes out rubble.
Suffer from into renal plevis for calculus in renal plevis or because ureteroscope rubble process careless manipulation causes ureteral calculi to be retracted
Person is feasible to have invasive procedures-percutaneous nephroscope lithotripsy stone-extraction operation (PCNL) or urethra Flexible ureteroscope laser lithotripsy stone-extraction operation of passing through.It is right
In row soft lens patient, surgical procedure is extremely complex, and surgical effect is bad, and patient needs to undertake times over hard videoendoscopic surgery expense
With.Therefore ureteral calculi is once retracted into renal plevis, is all sizable misfortune to patient and patient.
For current hard mirror URL, need to wash by water into mirror direction along ureteroscope to maintain ureter this hidden intracavitary
Visual area, and go out the residual stone smashed.But direct motion bath is easy to cause calculus and retracts into renal plevis, and majority Grade A hospital is using envelope at present
Stifled device avoids this problem, but plugging device can not stop direct motion water and flow into renal plevis, cause renal plevis pressure to increase, renal plevis pressure increases
Height can cause urine reversely to enter blood circulation of human body system, and pathogen is made to enter blood, cause bacteremia, postoperative pyrexia etc. many simultaneously
Disease is sent out, therefore clinician can only complete rubble operation under poor visual area, and need to inject frusemide and dexamethasone etc. in art
Drug alleviates symptom;And the calculus of powdered can be also driven in the wrong direction by plugging device gap into renal plevis, and adverse consequences is caused.

Stone adds, but operating difficulties, time-consuming and laborious;(2) it washes by water by jet water spout and by handle hole to rubble, by plug
Block so that rubble and flow reversely flow out together, but since plug is spring-like, between have the gap, in water-rinsing process
In, it is easy to rubble is poured by the gap of plug in renal plevis, causes to remove stone operative failure.
It can obtain current operation method from surgical procedure above there are drawbacks and be:
1, it is direct motion bath to provide visual area technology at present for URL operations, and calculus can pour renal plevis by flow, and operation is caused to be lost
It loses, treating method is to use ductus arteriosus occluder calculus, but plugging device can not stop flow and drive in the wrong direction to renal plevis at present, and renal plevis pressure increases
Height can cause urine reversely to enter blood circulation of human body system, and pathogen is made to enter blood, cause bacteremia, postoperative pyrexia etc. many simultaneously
Disease is sent out, therefore clinician can only complete rubble operation under poor visual area, and need to inject frusemide and dexamethasone etc. in art
Drug alleviates symptom;And the calculus of powdered can be driven in the wrong direction by plugging device gap into renal plevis.
2, current operation method causes the residual stone smashed in ureter not take out completely, when one section postoperative by patient at present
Between Self-discharged, effect is not very definite, for being likely to occur stone rank compared with maximum size is postoperative, again leads to ureteral obstruction,
Second operation is needed to treat.And bulk calculus removing method repeatedly passes in and out ureter gripping, operating process mainly by foreign body forceps at present
Cumbersome, ureter wound is serious.
