Abstract
Urinary bladder cancer (UBC) is dominantly the cancer of the elderly occurring primarily in the 6th, 7th and 8th decade
of life. The aim of this study was to evaluate diagnostic accuracy of ultrasound T-staging (UTS) of UBC in the group of
elderly patients. In 152 elderly patients referred to transabdominal ultrasound examination in two different facilities (76
each) due to various symptoms (primarily painless gross or microscopic haematuria) UBC was diagnosed. Initial UTS
at the moment of detection was performed and compared with fi nal histological T-staging (HTS). A high level of conformity
between UTS and HTS was detected. In a total of 152 patients with UBC there were 115 (75.66%) patients with complete
match between the UTS and HTS, 24 (15.79%) patients with minimal variation within one stage, and 13 (8.55%) patients
with one stage difference between the UTS and HTS. The best result was established for the stage T1, where the accuracy
was 94.5%. In other stages the accuracy was between 84.9% and 91.8%. The Youden’s index for all the stages was over
0.6. UTS has a high diagnostic accuracy, especially for stages T1 and T2. It is extremely useful tool in differentiating the
superfi cial UBC from the muscle-invasive one, being of signifi cant importance in planning the further treatment of elderly
patients and having important role in choosing appropriate surgical approach.
