Percutaneous nephrolithotomy is the modern minimal invasive technology for the treatment of urinary system calculus, one of kidney Therapeutic Method the most frequently used with ureteral calculus is treated for current Urology Surgery, it has the advantages such as wound is little, calculus clearance rate high, renal function injury is little, but there is also severe haemorrhage and infection risk. Percutaneous nephrolithotomy needs puncture expansion between skin and renal calices and sets up fistulation passage, then inserting sheath pipe (peeling sheath) and utilize pipe internal channel to be operated, kidney stoma is inserted kidney fistulation passage to play the effect of drainage of urine and hemostasis by compression through sheath pipe by routine after surgery. Just can insert in kidney owing to the diameter of kidney stoma is necessarily less than the diameter of sheath pipe and excess of the kidney matter fistulation passage, thus between excess of the kidney matter fistulation passage and kidney stoma, there is certain space, kidney stoma directly oppresses the limited efficiency of kidney fistulation passage wound surface hemostasis, may result in excess of the kidney matter fistulation passage continuous bleeding, if may result in severe hematuria in hemorrhage infiltration kidney, if blood clot blocks stoma can cause violent renal colic, if hemorrhage infiltration kidney circumferential play can form huge hematoma, normal complicated with severe infections. Serious kidney fistulation passage is hemorrhage jeopardizes patient vitals's safety, if expectant treatment is invalid, needs the hemostasis of row embolization of renal artery or open kidney to repair or excision, this not only can making patients's wound and medical expense burden, also result in the disappearance of renal function. In addition; percutaneous nephrolithotomy needs irrigate a large amount of normal saline to ensure that surgical field of view is clear through fistulation passage to kidney inner high voltage; but these infusion liquid often mix the infection urine containing a large amount of antibacterials; can be excessive in perirenal space along fistulation passage; severe infections can be formed in extensive and airtight retroperitoneal space; and very easily absorbed into serum forms urine source property pyemia, even result in patient's shock, death.
Kidney stoma most popular clinically at present is actual is the two-chamber latex or the silica gel urinary catheter that shorten length, as shown in Figure 1, its front end has drain side opening 01 to be connected with drainage channel 02 in pipe, an air bag 03 it is provided with after urinary catheter front end drain side opening 01, air bag 03 connects with a filling pipe 04, this filling pipe 04 extends to urinary catheter rear end along urinary catheter tube wall and draws, and forms Y-branch with drainage channel 02 rear end.After making it full by filling pipe to air bag water filling, urinary catheter of pulling back makes air bag be positioned at excess of the kidney matter fistulation passage nephrostoma place, thus realizing hemostasis by compression and preventing drainage tube from deviating from. Although above-mentioned kidney stoma solves the problem of urine drainage in kidney, serve the effect of certain hemostasis and fixing stoma, but in clinical practice, there is problems in that 1) kidney stoma frontal air bag is easily moved in the renal pelvis renal calices of roomy hydrops, it is impossible to closure compressing excess of the kidney matter fistulation passage internal orifice (renal calices side) conscientiously; 2) owing to kidney stoma diameter is less than excess of the kidney matter fistulation channel diameter, passage hemostasis can not directly be oppressed; 3) excess of the kidney matter fistulation passage collar extension (outside excess of the kidney matter) is not closed, and the space that excess of the kidney Zhi Lou road wound surface is hemorrhage and in kidney, urine can be passed through between fistulation passage and stoma continues excessive to perirenal space, easily causes infection. For preventing above-mentioned situation from occurring, surgical doctor is drawn to skin side frequently with firmly being pulled back by kidney stoma air bag and is fixed by stoma by skin closure silk thread mode, to play hemostasis by compression and to prevent stoma translocation, but there is serious pain after causing operation in patients in the tractive energetically of kidney and skin, and this processing mode haemostatic effect is extremely limited, kidney substantial damage and the water pocket situation causing stoma to be deviate from of breaking also happens occasionally.

For solving kidney fistulation passage bleeding problems, different researcheres devise the multiple kidney stoma possessing anastalsis. A kind of New drainage tube of CN202010364U patent disclosure such as bulletin in Patent Office of the People's Republic of China on October 19th, 2011, the front end of the elastic drainage tube of its design is provided with the diameter elastic end socket more than this body diameter of drainage tube, has one can run through the drainage tube passage thimble to its front end inside drainage tube. Thimble is relied on to elongate elastic drainage tube during use, after reducing the diameter of drainage tube body, reduce the diameter of drainage tube front-end end enclosure again, drainage tube is put in kidney fistulation passage, end socket after release recovers script diameter and is located just in excess of the kidney matter fistulation passage, thus oppressing wound surface to realize hemostasis. Although this Patent design has certain haemostatic effect, but without stoma fixed structure, there is the problem being difficult to avoid that stoma slips displacement. Additionally, Patent Office of the People's Republic of China on April 23rd, 2014, CN102599942B patent disclosure a kind of Nephrolithotomy mirror expansion of bulletin was stopped blooding stoma, its drainage catheter front end is provided with playing the elastic ball air bag of fixation in renal pelvis and being positioned the interior non-resilient cylindrical airbag playing direct hemostasis by compression effect of excess of the kidney matter fistulation passage, can have better hemostasis and fixed effect. But, the kidney fistulation channel diameter adopted clinically can alter a great deal, and after non-stretchable air bag expansion, cross section diameter of a circle is difficult to just mate with it, it has to the non-stretchable air bag preparing a variety of diameter specifications is just easy to carry out application. Once select error in it uses, or compressing passage hemostasis can not be satisfied with, or tearing excess of the kidney Zhi Lou road increases the weight of hemorrhage. Additionally, the kidney of severe dilation hydrops, the thinning deliquescing of the normal atrophy of its parenchymal tissue, at this moment after using air bag expansion in excess of the kidney matter fistulation passage, be likely to turn up or varus excess of the kidney Zhi Lou road wall wound surface jack-up, not only can not hemostasis by compression, severe haemorrhage can be caused on the contrary.Above-mentioned situation Patent Office of the People's Republic of China on May 29th, 2013 bulletin CN202950710U and on May 14th, 2014 bulletin the patent disclosure such as CN203591512U kidney fistulation passage in elastic bag use in be more easy to generation.
