Summary. CT diagnosis of the upper urinary tract transitional cell carcinomas (UUTCC) was evaluated. The aim of the study was to investigate which are the most reliable radiological signs for making difference between infiltrating and non infiltrating UUTCC.
Thirty eight patients with the histologically confirmed UUTCC and preoperatively performed CT scan were evaluated. CT was diagnostically sensitive in 100% of cases. Primary tumor was correctly staged in 52.6% of cases and nodal disease was recognized in 55% of cases. The most important radiological sign was filling defect (present in 28-73.6%). Non infiltrating neoplasm was most frequently present when the filling defect was isolated radiological sign (53.8%). The most important signs for deep infiltrating neoplasms are: infiltration of the kidney, distortion of the contour and renal mass effect. CT is the best single method but still not sufficiently precise for the preoperative staging of UUTCC.
Key words: Computer tomography, urothelial cancer, diagnosis

ODREDJIVANJE STADIJUMA TUMORA GORNJEG UROTELIJUMA KOMPJUTERIZOVANOM TOMOGRAFIJOM
Kratak sadržaj: Proučavana je dijagnoza tumora gornjeg urotelijuma pomoću kompjuterizovane tomografije (CT). Zadatak istraživanja bio je da analizira najznačajnije radiološke znake pomoću kojih se može učiniti diferencijacija infiltrativnih od ne-infiltrativnih tumora gornjeg urotelijuma.
Analizirano je 38 bolesnika sa histološki dokazanim tumorom gornjeg urotelijuma kod kojih je preoperativno učinjen CT. CT je otkrio oboljenje u 100% slučajeva. Primarni tumor je korektno procenjen u 52,6% a status limfnih žlezda u 55% bolesnika. Najznačajniji pojedinačni znak neinfiltrativnih tumora bio je prisustvo defekata u punjenju koje postoji kao samostalno kod 53,6% bolesnika. Najznačajniji znaci duboko infiltrativnih tumora su infiltracija bubrega, poremećaj konture bubrega i bubrežna masa. CT nije metoda od presudnog značaja za dijagnozu i lečenje tumora gornjeg urotelijuma.
