Ureteral stent. isicelo

Ngezinye izikhathi ngenxa yezizathu ezihlukahlukene, ukwephulwa kwamalungelo outflow ka umchamo ureter kungenzeka. Lokhu kungenzeka ngenxa ukufuduka ezinso, amahlule, njll

aphoyintimenti

Ureteral stent yakhelwe ukubuyisela umchamo ukugeleza. Kulula ukuze agobe tube, obekungadala ku ureter. Usebenzela sokukhipha umchamo ku imvelo esinyeni. Ureteral stent ukukhwezwa ngaphansi izifo ezithize esithathelanayo nezinso imisebenzi eziyinkimbinkimbi.

kudivayisi

Ubude stent ifinyelela 30 cm lapho ubukhulu tube-6 mm. Ukuze ipayipi urinary ngokuphepha endaweni nomunye emikhawulweni yaso ifakwe ikhoyili, olubizwa nangokuthi "ingulube umsila". Idivayisi efakwe usebenzisa cystoscope noma ureteroscope. Ureteral stent senziwa polyurethane noma abicah. Indawo yayo kufanele ibe bushelelezi, akufanele obala umchamo awubhekene nosawoti. Silicone kwaba ukumelana kakhulu ukwa nosawoti encrustation, kodwa ngenxa unenkululeko okusezingeni eliphezulu tube kunzima futhi ligcinwe ilungiswe isikhundla. Ukuze wehlise ikhono ukusabela stent ke ziphathwe hydrogel enamathela. Lokhu kwandisa ukuphila unit wakho.

Izinkinga emva inqubo stent ukubekwa

Iziguli esekhala dysuria, ukuchama kaningi, ukuchama okungalindelekile, nocturia. Lesi senzakalo kuyagcinwa kaningi ngokushesha ngemva nokubekwa ipayipi, ngezinye izikhathi kakhulu libizwa. Ukuze ugweme ekususweni stent, esimisiwe antispasmodics. Ameliorating waphawula ngemva kwezinsuku ezimbalwa. Ngezinye izikhathi iziguli esekhala ubuhlungu ohlangothini lwakhe futhi isisu. Isizathu sokuba ubuhlungu ohlangothini lwakhe - Reflux umchamo ngesikhathi ukuchama. ngezinye izikhathi egibele ureteral stent okubangela ukuvuvukala esithathelanayo ngomgudu womchamo. Ngokuba nokuvimbela yezinkinga-antibiotic ezinqunyiwe, nakuba ukusetshenziswa kwazo esikhathini eside esizayo akuyona kufiseleka, ngoba bangakwazi ukuhlakulela eziphilayo ukumelana.

Proximal kufuduka - isimo esibucayi ukuthi kwenzeka uma ufaka stent esifushane kakhulu kusukela ekupheleni distal yemvelo ezisontekile routing noma traumatizing elingenhla Calyx izinso ekupheleni proximal. Isikhathi eside okwatholakala ureteral stent ku kwehlukana yayo kungenzeka. Ureteral stent wahlukanisa zisuswe, okuyinto kwenziwa ureteroscopy, cystoscopy, noma ngesikhumba.

isicelo

A ureteral stent esetshenziselwa stenting we isimiso ureter ebukhoneni uhlelo kwezinso, ngamanye amazwi, uma kunenkinga nge outflow ka umchamo nezinso. izizathu ezahlukene - urological, neurologicheskie futhi iatrogenic. Ukuze urological zihlanganisa urolithiasis, izimila kule ureter, lo wendlala noma isinye, wendlala adenoma, cystic retroperitoneal. Ukuvimbela okuyinto ingeyona emkhakheni Urology - kokucindezelwa futhi amila e ureter izimila ngesikhathi kwamanye amasayithi, lymphomas ehlukahlukene lymphadenopathy. izimbangela Iatrogenic kukhona ukuvuvukala , kulandela ukugasela ukuthi kwakwenziwa ezithweni kwezitho zangasese, kanye ngemva radiotherapy.
