Morphometric Evaluation of Lower Pole Calyceal Spatial Anatomy in Normal Healthy Kidneys: A Comparison between Intravenous Urogram and Three-Dimensional Helical Computed Tomography
Journal Title: Isra Medical Journal - Year 2018, Vol 10, Issue 4
Abstract
OBJECTIVE: To compare the morphometric evaluation of lower pole calyceal anatomical factors between Intravenous Urogram and Three-Dimensional Helical Computed Tomography in healthy kidney donors in respect to their clinical importance. STUDY DESIGN: An observational/ cross-sectional study PLACE AND DURATION: At Islamabad Diagnostic Centre, Islamabad from 1st March 2016 to 30th May 2017. METHODOLOGY: Our patient population were selected potential kidney donors referred for Three-Dimensional Helical Computed Tomography. The features of lower pole calyces including Lower Calyceal Infundibular Length, Lower Calyceal Infundibular Width, and Lower Infundibulo-UreteroPelvic Angle between Intravenous Urogram and Three-Dimensional Helical Computed Tomography were measured using a ruler and a square for Intravenous Urogram images and three dimensional reconstruction for Helical Computed Tomography using workstation each by different investigator. The measured variables were compared individually. RESULTS: The mean age was 27.7 ± 7.6 years. The mean LCIL was 22.1 ± SD of 6.6 obtained from 3D-HCT while it was 26.9 ± SD of 6.8 in case of IVU (P-value of < 0.05). The mean LCIW was 4.5 ± SD of 2.2 obtained from 3D-HCT while it was 8.6 ± SD of 2.4 as obtained by IVU (P-value of < 0.05). For LIUPA, an angle of 53.5 ± SD of 13.9 with 3D- HCT was obtained whereas in case of IVU, it was 53.6 ± SD of 23.3 which was not significant (P-value of 0.49). CONCLUSION: 3D HCT is more advantageous against IVU in analysing the morphometric features of the lower pole anatomical factors of the kidney and it more accurately displays the lower polar calyceal spatial anatomy.
