“…scheme(4).After comparing the advantages and limitations of different imaging methods, and combining with the knowledge of the anatomical characteristics and clinical requirements of blood vessels in the donor kidney, most transplantation centers evaluate the anatomical structure and adjacent relation of the blood vessels in the donor kidney by using MDCT, the outcomes of which have attracted extensive attention and recognition (4). Computed tomography has become the imaging modality of choice for the assessment of blunt abdominal injuries in major trauma centers.…”

Background: Multidetector computed tomographic (MDCT) angiography has become a key imaging investigation for assessment of the renal vasculature challenging conventional angiography. Objective: To assess the diagnostic performance and accuracy of multi-detector computed tomography angiography in evaluation of renal vascular abnormalities. Subjects and Methods: Prospective study included 95 patients (60 males and 35 females) evaluated by MDCT renal аngiоgrаphy, divided into four groups .First group are renal donors prepared for renal transplant, Second group are patients with history of suspected renal trauma or post percutaneous nephrolithetomy hematuria ,Third group are patients suspected for renovascular hypertension . Fourth group are patients with renal masses assessed for preoperative angio-embolization & surgical guidance. MDCTA findings were correlated with conventional angiography or operative findings. Results: MCT angiography results show no significant statistical deference compared with intraoperative findings in first group, as well as compared with conventional angiography regards detection of pseudoaneurysmas in traumatic & post PCNL patients (P value > 0.05) in second group. In patients with suspected renovascular hypertension there was significant difference between renal artery Doppler findings & MDCT angiography as well as conventional angiography (P value <0.05). MDCT Angiography has AUC of 0.973, Sensitivity 93.3% and Specificity 90%. Conclusion: We can conclude that, MDCT Renal angiography is an excellent imaging investigation because it is a fast and non-invasive tool that provides detailed evaluation of normal renal vascular anatomy, variants &abnormalities .

“…8,9 The multislice spiral CT scanning technique and postprocessing procedures help to improve the accuracy and sensitivity of the detection of renal artery lesions. 10 However, CT angiography may require large amounts of iodinated contrast agent, 11 and the safety and diagnostic performance of this method should be further evaluated.…”

Objectives: Transplant renal artery stenosis is a frequently recognized complication of kidney transplant procedures. A single-center retrospective study was conducted to examine the use of 3-dimensional computed tomography reconstruction in diagnosing transplant artery stenosis. Materials and Methods: During 2013 at our center, 86 patients underwent kidney transplant. All patients underwent ultrasonographic analyses. Patients with clinically suspected transplant renal artery stenosis were examined by 3-dimensional computed tomog raphy reconstruction and were treated with endo vascular approaches or medically managed. Results: Ten patients were diagnosed with transplant renal artery stenosis by 3-dimensional computed tomography reconstruction. No evidence of contrastinduced nephrotoxicity was observed. Nine of the 10 patients underwent percutaneous transluminal angio plasty, whereas the remaining patient was treated conservatively. Procedural success rate was 100%. Patients were followed for a mean period of 20 ± 3 months. Blood pressure improved from a mean of 163/90 to 132/73 mm Hg at the end of the follow-up period. In the 9 patients who underwent angioplasty, serum creatinine improved from 198 ± 24 to 134 ± 16 µmol/L at the end of the follow-up period. The cystatin C level in some patients declined after interventional therapy. Conclusions: Three-dimensional computed tomography reconstruction is a safe choice for patients who present with increased serum creatinine levels and refractory hypertension. Percutaneous transluminal angioplasty is the preferred therapeutic technique for transplant renal artery stenosis.

The accessory renal arteries (ARAs) are a well‐described variant of the renal vasculature with clinical implications for radiologists, surgeons, and clinicians. The aim of the present systematic review with meta‐analysis was to estimate the pooled prevalence of ARAs, including their variant number, origin, and termination, and to highlight symmetrical and asymmetrical morphological patterns. The systematic review used four online databases in accordance with PRISMA 2020 and Evidence‐based Anatomy Workgroup guidelines. R programming software was used for the statistical meta‐analysis. A total of 111 studies were considered eligible for our initial aim. The typical renal artery (RA) anatomy (a single bilateral vessel) was identified in 78.92%; the overall ARA prevalence was estimated at a pooled prevalence of 21.10%. The estimated pooled prevalence of one, two, three, and four ARAs were 18.67%, 1.80%, 0.01%, and <0.01%. The ARAs have been the subject of extensive research owing to their clinical importance, including in kidney transplantation surgery and resistant hypertension therapy. Knowledge of the typical and variant anatomy of RAs is essential for anatomists, radiologists, surgeons, and clinicians in order to avoid misunderstanding, complications, and iatrogenic injury.
