Technical field
The present invention relates to a kind of rapid-dissoved anti-reflux ureter brackets in part.
Background technology
Ureter rack tube is extensive in urological applications of compounds, and it is broken to be suitable for kidney, ureter stone operation and external knock wave
Shi Qian;The external compressing of ureter need to release the patient of obstruction;Suitable for the treatments such as after kidney transplant, ureterostenosis dilatation, portion
Patient is divided to need Preserving time.Ureter bracket both-side ends crimp " pigtail-shaped " in pairs at present, as shown in Figure 1, last before and after holder
" J " shape is held into, be otherwise known as double ‘J' tube.For end direction opposite curvature at circle shape, one end is located at kidney Meng, and the other end is located at wing
Guang.Rack body is placed in ureteral lumen.Drainage of urine can be played after implantation ureter, prevent ureterostenosis and adhesion blocking etc.
Effect.Ureter bracket is mostly made of medical macromolecular materials such as silicon rubber or polyurethane at present, and Partial tumors patient needs long-term
Place is mostly that metal is made.The application of ureter rack tube improves success rate of operation, but still can after indwelling ureter rack tube
Cause some complication, common are:With the relevant symptom of reflux, pain in the back when such as pain in the back, urination, urine
Frequently, the irritations sign of bladder such as urgent urination and odynuria, urinary infection, ureter rack tube calculus etc..Wherein, irritation sign of bladder and
Reflux is current letter major issue to be solved, for needing the patient of Preserving time double J pipe even more tight
Further increasing for therapeutic effect is limited again, and can lead to severe complication.
The reason of backflowing essentially consist in ureter rack tube be it is a kind of can be defeated after indwelling tube of double-J with the conduit of double take-off
The anti-reflux mechanism of urinary catheter the bladder wall inner segment seriously weakens or disappears, when intravesical pressure is more than renal plevis and intra-ureteral pressure
When power, urine in bladder will inevitably occur and backflow to ureter and renal plevis.In addition, after indwelling ureter bracket, urine
Liquid is constantly drained, and renal pelvis ureters circular cone loses full stimulation, is caused ureter rhythmicity to be wriggled and is obviously weakened or disappear, increases
Add urine reflux rate probability and severity.
Reflux influences therapeutic effect, especially needs long-term layer.Backflowing causes renal plevis pressure to increase
Add, renal papilla and cortex renis atrophy can be caused for a long time by backflowing, and damage renal function.Foreign matter resides in urinary system for a long time, and bacterium is easily fixed
It plants and causes urinary infection in ureter bracket;Ureteral peristalsis decrease makes urinary system self-cleaning ability decline, urinary tract in increase
Infect probability.Prolonged and repeated Renal pelvic pressure power increases and infection destructible kidney, and it is thinning to even result in cortex renis, greatly influences
Therapeutic effect.But it there is no effective solution at present, it is suggest that patient drinks more water and frequently urinates more, so that bladder is in inanition as possible
State, avoids bladder excessive full and abdominal pressure excessively increases;Antibiotic, some patientss is applied to be forced to replace urine output when infecting
Pipe holder.But these methods can not fundamentally solve bladder irritation and reflux and related complication.
Several anti-reflux ureter brackets being currently known design:One-way valve, pipe peripheral hardware anti-reflux valve are set in pipe
Film, end set valve etc., and ureterovesical junction is designed as draught line by some, and urine output pipeline section still uses traditional design, though
Short anti-reflux mechanism in tubal bladder wall is utilized, but still can seriously inhibit ureteral peristalsis, it is difficult to fully drainage.It is external
Report has similar product MiniJFil, substitutes part ureter bracket with silk thread, but because of silk thread soft texture, laparoscopic renal
It is difficult to place from renal plevis side in broad-mouthed receptacle for holding liquid plasty, lower end ureter structure, which is embedded in rapidly dissolvable ureter bracket, to be solved
