I-perfusion ye-renal scintiscan

I-scintiscan ye-renal perfusion luvavanyo lwamayeza enyukliya. Isebenzisa isixa esincinci sezinto ezinemitha ye-radio ukwenza umfanekiso wezintso.

Uya kucelwa ukuba uthathe amayeza oxinzelelo lwegazi abizwa ngokuba yi-ACE inhibitor. Iyeza linokuthathwa ngomlomo, okanye linikezwe ngomthambo (IV). Iyeza lenza ukuba uvavanyo luchaneke ngakumbi.

Uya kulala phantsi kwitafile yesikena kungekudala emva kokuthatha iyeza. Umboneleli wokhathalelo lwempilo uya kutofa inani elincinci lezinto ezinemitha yeathom (radioisotope) komnye wemithambo yakho. Imifanekiso yezintso zakho ithathwa njengoko izinto ezinemitha yeathom zihamba kwimithambo yommandla. Uya kudinga ukuhlala uthe cwaka kulo lonke uvavanyo. Iskena sithatha malunga nemizuzu engama-30.

Malunga nemizuzu eli-10 emva kokuba ufumene into enemitha ye-radioactive, uyakunikwa umchamo ("ipilisi yamanzi") ngomthambo. Eli yeza liyanceda ukwenza uvavanyo luchane ngakumbi.

Unokubuyela kwimisebenzi yesiqhelo kanye emva kovavanyo. Kuya kufuneka usele ulwelo oluninzi ukuze uncede ususe izinto ezinemitha yeathom emzimbeni wakho. Uvavanyo luyakwenza uchame rhoqo kwiiyure ezininzi emva kovavanyo.

Uya kucelwa ukuba usele amanzi amaninzi phambi kovavanyo.

Ukuba ngoku uthatha i-ACE inhibitor yoxinzelelo lwegazi oluphezulu, unokucelwa ukuba uyeke ukuthatha iyeza lakho phambi koviwo. Soloko uthetha nomboneleli wakho ngaphambi kokuba uyeke nawaphi na amayeza akho.

Unokucelwa ukuba unxibe ilokhwe yasesibhedlele. Susa bonke ubucwebe kunye nezinto zentsimbi ngaphambi kokuskena.

Unokuziva inani elincinci lentlungu xa inaliti ifakiwe.

Kuya kufuneka uhlale uzolile ngexesha lokuskena. Uya kuxelelwa xa ufuna ukutshintsha izikhundla.

Kunokubakho ukungonwabi njengoko isinyi sakho sigcwalisa umchamo ngexesha loviwo. Xelela umntu oqhuba uviwo ukuba kufuneka uchame ngaphambi kokuba kugqitywe ukuskena.

Uvavanyo luvavanya ukuhamba kwegazi kwizintso. Isetyenziselwa ukufumanisa ukuxinwa kwemithambo ebonelela ngezintso. Le yimeko ebizwa ngokuba yi-renal artery stenosis. Umthambo obalulekileyo we-renal stenosis unokuba sisizathu soxinzelelo lwegazi oluphezulu kunye neengxaki zezintso.

Ukuhamba kwegazi kwizintso kubonakala kuyinto eqhelekileyo.

Iziphumo ezingaqhelekanga kwiskeni kunokuba ngumqondiso we-renal artery stenosis. Isifundo esifanayo esingasebenzisi i-ACE inhibitor singenziwa ukuqinisekisa isifo.

Ukuba ukhulelwe okanye unesi, umboneleli wakho unokufuna ukuhlehlisa uvavanyo. Kukho umngcipheko othile obandakanyekayo kwi-ACE inhibitors. Abafazi abakhulelweyo akufuneki bathathe la mayeza.

Inani le-radioactivity kwisitofu lincinci kakhulu. Phantse yonke i-radioactivity ihambile emzimbeni kwisithuba seeyure ezingama-24.

Ukuphendula kwizinto ezisetyenzisiweyo ngexesha lovavanyo kunqabile, kodwa kunokubandakanya irhashalala, ukudumba, okanye i-anaphylaxis.

Iingozi zentonga yenaliti zincinci, kodwa zibandakanya usulelo kunye nokopha.

Olu vavanyo lunokuchaneka kancinci kubantu esele benesifo sezintso. Thetha nomboneleli wakho ukumisela ukuba olu luvavanyo olufanelekileyo kuwe. Ezinye iindlela zolu vavanyo zii-MRI okanye i-CT angiogram.
