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.

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.
