Correlation of computerized tomography and intravenous pyelography in the evaluation of pelvicaliceal anatomical measurements

Objective: Comparison of computed tomography and reference imaging intravenous pyelography in anatomical measurements of pelvicalyceal system. Material and Methods: 47 patients and 59 renal units with both computed tomography and intravenous pyelography images were included in the study. The measurements of lower pole infundibulopelvic angle, infundibular length and infundibular width were performed in each kidney and the results were compared between computed tomography and intravenous pyelography groups. Results: Of the 47 patients who were taken to study, 21 were female and 26 were male. The mean age of the patients was 42.87. Of the 59 renal units, 26 were left, 33 were right kidney. There was no statistically significant difference between the infundibulopelvic angle, infundibular length and infundibular width measurements of the patients measured by computed tomography and intravenous pyelography (p = 0.773, p = 0.931, p = 0.850). It was seen that the measurements of both methods correlated to each other. Conclusion: With similar results to intravenous pyelography in the anatomical measurements of the pelvicalyceal system, computed tomography may be useful in patients who can not undergo intravenous pyelography imaging for any reason
