Sawirka shucaaca ayaa muhiim u ah dhamaystirka xogta kiliinikada iyo kaalmaynta urologists si loo sameeyo maaraynta bukaanka ku haboon. Hababka sawir-qaadista ee kala duwan, CT-ga ayaa hadda loo tixgaliyaa heerka tixraaca ee qiimaynta cudurrada kaadi mareenka sababtoo ah helitaankeeda ballaaran, waqtiga baaritaanka degdega ah, iyo qiimeynta dhamaystiran. Gaar ahaan, CT urography.
TAARIIKHDA
Waagii hore, urography xididka (IVU), oo sidoo kale loo yaqaan "urography excretory urography" iyo/ama "xididka xididada," ayaa ugu horreyn loo isticmaalay si loo qiimeeyo marinka kaadida. Farsamada waxay ku lug leedahay shucaaca ugu horreeya ee cad oo ay ku xigto duritaanka xididada ee wakiilka ka soo horjeeda biyaha-milmi leh (1.5 ml/kg miisaanka jirka). Ka dib, sawirro taxane ah ayaa lagu helaa waqtiyo gaar ah. Xaddidaadaha ugu weyn ee farsamadaan waxaa ka mid ah qiimeynta laba-geesoodka ah iyo qiimeynta maqan ee anatomy ee ku xigta.
Ka dib markii la soo bandhigay sawir-gacmeedka kombiyuuterka ah, IVU ayaa si ballaaran loo isticmaalay.
Si kastaba ha ahaatee, kaliya 1990-meeyadii, iyada oo la hirgeliyay tignoolajiyada helical, waqtiyada iskaanka ayaa si weyn loo dardargeliyay si meelo badan oo jirka ah, sida caloosha, lagu baran karo ilbiriqsiyo gudahood. Markii ay soo ifbaxday tignoolajiyada kala duwan ee 2000-meeyadii, xallinta booska ayaa la cusboonaysiiyay, taasoo u oggolaanaysa aqoonsiga kaadi-mareenka kaadi-mareenka sare iyo kaadi-haysta, iyo CT-Urography (CTU) ayaa la aasaasay.
Maanta, CTU waxaa si weyn loogu isticmaalaa qiimeynta cudurrada kaadi mareenka.
Tan iyo maalmihii hore ee CT, waxaa la ogaa in raajooyinka tamar kala duwan ay kala saari karaan agabyada tirooyinka atomiga ee kala duwan. Ma ahayn ilaa 2006 in mabda'aani si guul leh loogu dabaqay daraasadda unugyada bini'aadamka, ugu dambeyntii taasoo keentay in la soo bandhigo nidaamka dual-energy CT (DECT) ee ugu horreeya ee maalinlaha ah ee daaweynta. DECT waxay isla markiiba muujisay ku habboonaanta qiimaynta xaaladaha cudurrada kaadi mareenka, oo u dhexeeya burburka walxaha calculi kaadida ilaa qaadashada iodine ee cudurrada kaadi mareenka.
faa'iido
Hab-maamuusyada CT-ga ee caadiga ah waxaa ka mid ah sawirada isbarbardhiga hore iyo wajiyo badan. Sawir-qaadayaasha casriga ah ee CT-ga waxay bixiyaan xogta mugga leh ee lagu dhisi karo diyaarado badan iyo dhumucdiisuna isbedbedesho, si loo ilaaliyo tayada muuqaalka wanaagsan. CT urography (CTU) waxay sidoo kale ku tiirsan tahay mabda'a polyphasic, iyada oo diiradda saareysa marxaladda "baxa" ka dib markii wakiilka ka soo horjeeda uu ku shaandheeyay nidaamka ururinta iyo kaadiheysta, asal ahaan abuurista urogram IV oo leh isbarbardhiga unugyada si weyn loo hagaajiyay.
XADKA
Xitaa haddii sawir-gacmeedka kombiyuuterka ee isbar-bar-ku-bar-ku-ku-saarku yahay halbeegga tixraaca ee sawirka hore ee kaadi-mareenka, xaddidaadaha dabiiciga ah waa in wax laga qabtaa. Soo-gaadhista shucaaca iyo isbar-bardhigga nephrotoxicity ayaa loo arkaa dib-u-dhacyo waaweyn. Yaraynta qiyaasta shucaaca ayaa aad muhiim u ah, gaar ahaan bukaanada da'da yar.
Marka hore, habab kale oo sawir sida ultrasound iyo MRI waa in had iyo jeer la tixgeliyo. Haddii tignoolajiyadaasi aysan bixin karin macluumaadka la codsaday, waa in tallaabo laga qaadaa sida uu dhigayo borotokoolka CT.
Baadhitaanka CT-ga ee is-barbar-dhigga ahi waa ka mamnuuc bukaannada xasaasiyadda u leh wakiilada shucaaca iyo bukaannada qaba shaqada kelyaha ee daciifka ah. Si loo yareeyo nephropathy isbarbardhiga, bukaanada qaba heerka shaandhaynta glomerular (GFR) ka yar 30 ml/min waa in aan la siinin warbaahinta isbarbardhiga iyada oo aan si taxadar leh loo miisaamin khataraha iyo faa'iidooyinka, waana in si taxadar leh loogu isticmaalo bukaanada leh GFR inta u dhaxaysa. 30 ilaa 60 ml/daqiiqo bukaanada.
MUSTAQBALKA
Xilliga cusub ee daawada saxda ah, awoodda lagu ogaanayo xogta qiyaasta ee sawirada shucaaca waa caqabad hadda iyo mustaqbalka. Habkan, oo loo yaqaan radiomics, waxaa markii ugu horreysay soo saaray Lambin 2012 waxayna ku saleysan tahay fikradda ah in sawirada bukaan-socodka ay ka kooban yihiin astaamo tiro ah oo ka tarjumaya pathophysiology hoose ee unugyada. Isticmaalka tijaabooyinkan waxay wanaajin kartaa go'aan-qaadashada caafimaadka oo waxay heli kartaa meel bannaan gaar ahaan Oncology, taasoo u oggolaanaysa, tusaale ahaan, qiimaynta deegaanka-yar ee kansarka iyo saamaynta doorarka daawaynta. Dhowrkii sano ee la soo dhaafay, daraasado badan ayaa lagu sameeyay codsiga habkan, xitaa qiimeynta kansarka kaadi mareenka, laakiin tani waxay sii ahaaneysaa mudnaanta cilmi-baarista.
