“…Numerous studies have shown that CTA and CTU have a similar accuracy for the evaluation of anatomical features of the kidney and collecting system when compared to intraoperative findings. [ 24 25 26 27 ] The results of this study are also in accordance with the findings of the mentioned studies.…”

Objectives:To evaluate the accuracy of triple-bolus computed tomography urography (CTU) as a surrogate of intravenous pyelography (IVP) for determining the anatomy of the urinary collecting system in living kidney donors.Materials and Methods:In an analytic descriptive cross-sectional study, 36 healthy kidney donors were recruited during 12 months. Preoperative IVP and CTU were utilized to evaluate kidneys’ anatomy; major and minor calyces and variation were used as anatomical indices to compare the accuracy of CTU and IVP; the images were then compared to surgical findings.Results:Thirty-six kidney donors (92% male; mean age: 28 ± 6 years) were enrolled in this study. The kappa coefficient value was significant and almost perfect for the CTU and IVP findings in detecting the pattern of calyces (kappa coefficient 0.92, asymptotic 95% confidence interval 0.86–0.97). Anatomic variations or anomalies of the urinary collecting system included the bifid pelvis (5.6%), duplication (8.3%), and extra-renal pelvis (2.8%). Both the sensitivity and specificity of CTU in the detection of the anatomy and variations were 100%; the sensitivity and specificity of IVP were 83.3% and 100%, respectively.Conclusions:The triple-bolus preoperative CTU can be considered an alternative to IVP for assessing the anatomy of the urinary collecting system.

Die Computertomographie (CT) hat sich seit Einführung der Einschicht-CT vor mehr als 30 Jahren zunehmend weiterentwickelt: Eckpunkte sind die Entwicklung der Spiral-CT und die Einführung der Multidetektortechnik. Die Spiral-CT ermögli-cht eine kontinuierliche Datenakquisition, während der Patient durch den Tomographen bewegt wird. Die Multidetektor-CT (MDCT) führt zu einer deutlichen Erhöhung der Akquisitionsgeschwindigkeit und der longitudinalen Auflösung [8]. Durch die technische Weiterentwicklung haben sich die Anwendungsmöglichkeiten der CT erweitert, was auch Einfluss auf die Bildgebung bei Nieren-und Hochdruckerkrankungen hat.

Abstract: The findings recorded in this study indicate that noninvasive preoperative planning with 64-row multidetector CTA and CTU is a reliable "one-stop shopping" method of examination for potential living kidney donors.
