Isizathu sokuba iintlungu ecaleni - reflux umchamo ngexesha ukuchama. maxa wambi Onyuswe ureteral stent ebangela ukudumba ezosulelayo ye womchamo. Kuba ekuthinteleni iingxaki i-zintsholongwane emiselweyo, nangona ukusetyenziswa kwazo ixesha elide akufuneki, ngenxa yokuba bakwazi ukuphuhlisa eziphilayo ukumelana.

yokufudukela Proximal - kwingxaki kakhulu ukuba kwenzeka xa ufaka stent elifutshane kakhulu ukusuka ekupheleni distal ngemvelo ephinyaphinyelayo elifaneleyo ayikaphuhli okanye traumatizing ephezulu uluthi kidney ekupheleni proximal.
