Background: Computed tomography urography (CTU) is an efficient radiological examination for the evaluation of urinary system disorders. However, the procedure exposes patients to a substantial amount of radiation dose associated with increased cancer risks. Objectives: To determine computed tomography (CT) dose index following CTU and to evaluate organs equivalent doses and cancer-induced risks. Materials and Method: A prospective cohort study was carried out at a tertiary health facility in Kano, Northwestern Nigeria. Ethical approval was sought and obtained. Patients Demographics scan parameters and CT radiation dose data were obtained from patients that had CTU procedure. Effective dose (ED), organ equivalent doses, and cancer risks were estimated using SPSS statistical software version 16 and CT dose calculator software. Results: A total of 56 consented patients were included in the study, consisting of 29 males and 27 females. Radiation dose data for CTU was estimated as follows: dose length product (2,320 mGy*cm), computed tomography dose index (9.67 mGy), and ED (34.5 mSv). The probability of cancer risks was also estimated to be 600 per a million CTU examinations. Conclusion: The study revealed that the radiation dose for CTU is considerably high with increase in cancer risks probability. Variations in ED between studies suggest that optimization is not fulfilled. Patient radiation dose estimate should be taken into consideration when imaging protocols are planned for CTU.
