Isivikelo Sokufinyelela E-Ureteraliyithuluzi lezokwelapha elisetshenziswa ku-urology ukuze kube lula ukufakwa kwezinsimbi, njenge-ureteroscopes, ku-ureter kanye nezinso ngesikhathi sezinqubo ezingangenisi kakhulu. Liyipayipi elingenalutho, eliguquguqukayo elihlinzeka ngendlela ezinzile, elivikela i-ureter ekulimaleni futhi lithuthukise ukusebenza kahle kwezinqubo ezifana nokususwa kwamatshe, i-tumor biopsy, noma ukwelashwa kwe-stricture. Ama-ureteral access sheaths angamathuluzi abalulekile ku-endourology yesimanje, okuthuthukisa kokubili ukuphepha kwesiguli kanye nempumelelo yenqubo.

I-Ureteral Access Sheath (UAS) yohlobo lwe-Y iyithuluzi elikhethekile le-urological elenzelwe ukusiza ukuhlinzwa kwe-Retrograde Intrarenal Surgery (RIRS), ikakhulukazi ekwelapheni amatshe ezinso. Isici salo esichazayo isixhumi esinomumo we-Y ekugcineni kwaso okuseduze, esihlinzeka ngezindlela ezimbili ezizimele: esinye se-scope/izinsimbi zokuhlinzwa eziyinhloko kanye nesesibili esizinikele sokunisela okuqhubekayo noma ukudlula kwamathuluzi asizayo. Lo mklamo unikeza ukulawula okuphezulu phezu kokuguquguquka koketshezi ngaphakathi kwezinso uma kuqhathaniswa nama-sheath ajwayelekile, okuthuthukisa kokubili ukuphepha nokusebenza kahle.
