Ukujonga ngemitha kubalulekile ukongeza idatha yeklinikhi kunye nokuxhasa oogqirha be-urologist ekusekeni ulawulo olufanelekileyo lwesigulana. Phakathi kweendlela ezahlukeneyo zokujonga imifanekiso, i-computed tomography (CT) okwangoku ithathwa njengomgangatho oqhelekileyo wokuvavanya izifo ze-urological ngenxa yokufumaneka kwayo ngokubanzi, ixesha lokuskena ngokukhawuleza, kunye novavanyo olupheleleyo. Ingakumbi, i-CT urography.
IMBALI
Ngaphambili, i-intravenous urography (IVU), ekwabizwa ngokuba yi-"excretory urography" kunye/okanye "i-intravenous pyelography," yayisetyenziswa kakhulu ukuvavanya indlela yomchamo. Le ndlela ibandakanya i-radiograph yokuqala ecacileyo elandelwa yi-intravenous injection ye-water-soluble contrast agent (1.5 ml/kg ubunzima bomzimba). Emva koko, uthotho lwemifanekiso lufunyanwa ngamaxesha athile. Imida ephambili yale ndlela ibandakanya uvavanyo olunemilinganiselo emibini kunye novavanyo olungekhoyo lwe-anatomy ekufutshane.
Emva kokuqaliswa kwe-computed tomography, i-IVU iye yasetyenziswa kakhulu.
Nangona kunjalo, kuphela ngeminyaka yoo-1990, ngokuqaliswa kwetekhnoloji ye-helical, amaxesha okuskena akhawuleziswa kakhulu kangangokuba iindawo ezinkulu zomzimba, njengesisu, zazinokufundwa ngemizuzwana. Ngokufika kwetekhnoloji ye-multi-detector ngeminyaka yoo-2000, isisombululo sendawo saphuculwa, savumela ukuchongwa kwe-urothelium yendlela ephezulu yomchamo kunye nesinyi, kwaye kwasekwa i-CT-Urography (CTU).
Namhlanje, i-CTU isetyenziswa kakhulu kuvavanyo lwezifo zomchamo.
Ukususela kwimihla yokuqala ye-CT, kwaziwa ukuba ii-spectra ze-X-ray zamandla ahlukeneyo zinokwahlula izinto ezinamanani ahlukeneyo e-athomu. Lo mgaqo wasetyenziswa ngempumelelo kufundo lwezicubu zomntu, ekugqibeleni wakhokelela ekungenisweni kwenkqubo yokuqala ye-CT yamandla amabini (DECT) kwimisebenzi yemihla ngemihla yeklinikhi. I-DECT ibonakalise ngoko nangoko ukuba ifanelekile kuvavanyo lweemeko zesifo sendlela yomchamo, ukusuka ekuqhekekeni kwezinto kwi-calculi yomchamo ukuya ekuthathweni kwe-iodine kwi-malignancies yomchamo.
inzuzo
Iiprotokholi ze-CT zemveli zihlala ziquka imifanekiso yangaphambi kokungafani kunye neyasemva kokungafani. Iiskena ze-CT zanamhlanje zibonelela ngeeseti zedatha ye-volumetric ezinokwakhiwa ngokutsha kwiindawo ezininzi kunye nobukhulu besilayi obuguquguqukayo, ngaloo ndlela zigcina umgangatho womfanekiso ogqwesileyo. I-CT urography (CTU) ikwaxhomekeke kumgaqo we-polyphasic, igxile kwisigaba "sokukhupha" emva kokuba i-agent yokungafani ihluzile kwinkqubo yokuqokelela kunye nesinyi, ngokuyintloko idala i-IV urogram ene-tissue contrast ephucuke kakhulu.
UMDA
Nokuba i-computed tomography ephuculweyo yeyona ndlela isetyenziswayo xa kufotwa indlela yokuqala yomchamo, kufuneka kujongwane nemida ekhoyo. Ukuvezwa kwimitha kunye ne-contrast nephrotoxicity zithathwa njengeziphene ezinkulu. Ukunciphisa idosi yemitha kubaluleke kakhulu, ingakumbi kwizigulane ezincinci.
Okokuqala, iindlela ezahlukeneyo zokuthatha imifanekiso ezifana ne-ultrasound kunye ne-MRI kufuneka ziqwalaselwe rhoqo. Ukuba ezi teknoloji azikwazi ukubonelela ngolwazi oluceliweyo, kufuneka kuthathwe amanyathelo ngokwemigaqo ye-CT.
Uvavanyo lwe-CT oluphuculweyo aluvumelekanga kwizigulana ezine-allergy kwiiarhente ze-radiocontrast kunye nezigulana ezingasebenzi kakuhle kwezintso. Ukunciphisa i-nephropathy ebangelwa yi-contrast, izigulana ezine-glomerular filtration rate (GFR) engaphantsi kwe-30 ml/min akufuneki zinikwe i-contrast media ngaphandle kokuvavanya ngononophelo iingozi kunye neenzuzo, kwaye kufuneka zisetyenziswe ngononophelo kwizigulana ezine-GFR ezikumgama we-30 ukuya kwi-60 ml/min kwizigulana.
IKAMVA
Kwixesha elitsha lezonyango ezichanekileyo, ukukwazi ukufumana idatha yobungakanani kwimifanekiso ye-radiological ngumceli mngeni wangoku nowexesha elizayo. Le nkqubo, eyaziwa ngokuba yi-radiomics, yaqalwa ukwenziwa nguLambin ngo-2012 kwaye isekelwe kwingcamango yokuba imifanekiso yeklinikhi iqulethe iimpawu zobungakanani ezinokubonisa i-pathophysiology esisiseko yezicubu. Ukusetyenziswa kwezi zilingo kunokuphucula ukwenziwa kwezigqibo zonyango kwaye kufumane indawo ngakumbi kwi-oncology, okuvumela, umzekelo, uvavanyo lwendalo esingqongileyo yomhlaza kunye nefuthe kwiindlela zonyango. Kwiminyaka embalwa edlulileyo, kwenziwe izifundo ezininzi malunga nokusetyenziswa kwale ndlela, nokuba kuvavanyo lwe-urothelial carcinoma, kodwa oku kuhlala kuyilungelo lophando.
