“…In a previous report, we outlined the importance of clinicoradiological review of errors in live donor MDCTA [50]. Following one missed accessory artery and one missed venous anomaly, collimated slice width was reduced with greater vigilance for accessory and early‐branching arteries.…”

Summary The performance of multidetector computed tomography (CT) angiography was assessed in the pre‐operative evaluation of live renal donors. Between July 1998 and March 2006, 156 consecutive patients underwent open donor nephrectomy following pre‐operative multidetector CT angiography (MDCTA). Operative notes were compared with radiological reports and discrepancies identified. MDCTA missed five of 28 accessory arteries (four visible with hindsight), accuracy of 96%. Of 30 early‐branching renal arteries, eight were missed (all visible with hindsight), accuracy 95%. MDCTA missed only one of 13 venous anomalies (accuracy 97%) and also missed the only duplicated collecting system: both were undetectable with hindsight. Following modifications to image acquisition and interpretation sensitivity, negative‐predictive value and accuracy were significantly increased. The results were compared with pooled data from published studies of live donor imaging. This study and previous studies of MDCTA had improved sensitivity for arterial and venous anomalies over single detector CT angiography and MR angiography. We conclude that multidetector CT angiography is an accurate modality in the pre‐operative evaluation of live renal donors. Regular communication between the transplant surgeon and the radiologist is paramount to improve reporting of surgically relevant anatomy. Mechanisms should exist for auditing and improving pre‐operative imaging in any live donor programme.

“…For comparison, the accuracy of CT angiography -the current gold standard -is within similar ranges between 85 and 93% [5,7,18,19] . In this series, MRA failed to depict some polar vessels, missing 4 of the 17 that were encountered.…”

Introduction: Planification of living donor nephrectomy requires exact knowledge of the renal vascular architecture because of the high prevalence of anatomical variants. After magnetic resonance angiography (MRA) challenged CT angiography for preoperative assessment over the last years, we revisit in this study the reliability of MRA as the sole preoperative assessment for living donor nephrectomy. Method: We compared the radiological findings of MRA performed as the sole radiological procedure in 44 living kidney donors with perioperative anatomy to verify its sensitivity and to validate its systematic use in the preoperative assessment for living donor nephrectomy. Results: 22 anatomical variants were found in 16 patients (16/44 = 36%). In 4 patients, a polar artery (3 superior, 1 inferior) was not seen by MRA and was detected during surgery (open nephrectomy). Supposing the anatomical variants it described on the opposite side of the nephrectomy are real, sensitivity of this technique in this series is 40/44 (91%) for arterial and 100% for venous imaging. Conclusion: MRA as the sole radiological preoperative assessment performed by a single radiologist with specific expertise and preoperatively reviewed with the harvesting surgeon has been validated as the sole radiological preoperative assessment for living donor nephrectomy at our institution.

“…The aging human population and continuous, increased demand for kidney transplantation have forced the liberalisation of the above-mentioned principles, which is particularly important considering that renal transplantation surgery is the therapeutic method of choice in patients with end-stage renal failure [13,19].…”
