The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa. The postoperative period was uneventful, and at 8 months from the surgery, the graft remains functional. The surgical repair of renal artery aneurysms followed by immediate kidney transplantation is a safe technique and an effective replacement therapy for recipients. The incidental finding of isolated aneurysmal disease in renal arteries should not exclude graft potential availability for transplantation following repair.

Introduction: With the present disparity between organ availability and recipient demands, we reported our experience in transplanting kidneys with renal artery aneurysm after back-table reconstruction.Methods: Four patients were identified. The repair consisted of excision of the aneurysm with ostial closure, and for one of the cases, an ovarian vein patch was used. We reviewed the safety and outcomes of this procedure. All donors were asymptomatic before surgery and were diagnosed incidentally during living donor evaluation. The nephrectomies performed were hand-assisted laparoscopic approaches. All recipients had followup renal function and ultrasound duplex of renal artery at six and 12 months and then annually.Results: The mean age of the recipients was 28.7 years (range 3‒45). The mean size of the aneurysm was 7.4 ± 2.7 mm. All patients had immediate graft function with median serum creatinine of 1.9 ± 1.5 mg/dL at discharge. The average length of hospital stay was 6.25 ± 2.6 days. They also maintained good renal function with an average estimated glomerular filtration rate (eGFR) of 102.8 mL/min/1.73m2 (range 53.4‒199 mL/min/1.73m2) and patent vessels at one year. One patient suffered from acute antibody-mediated rejection and lost his graft (medication non-compliance). One patient had two simultaneous benign renal cysts that were resected. Three of the kidneys were right-sided and one left. Mean cold ischemia time was 86 ± 18 minutes. No deaths have been recorded.Conclusions: Transplanting kidneys with a renal artery aneurysm after ex-vivo repair is safe and the outcomes are encouraging. Also, it may play an important role in

INTRODUCTION Renal artery aneurysms is relatively uncommon with reported incidence ranges from 0.3% to 1%. However, considering all visceral artery aneurysms the percentage of renal artery aneurysms is relatively high between 15-25%. The distal forms of renal artery aneurysms sometimes require "ex vivo" reconstruction and kidney autotransplantation. CASE REPORT A 75-year-old male presented with the right abdominal and back pain. He suffered from a long history of arterial hypertension and chronic renal failure over the last few months (urea blood = 19.8 mmol/l; creatinine = 198 mmol/l). Duplex ultrasonography showed abdominal aortic aneurysm. Subsequent translumbarangiography revealed juxtarenal abdominal aortic aneurysm associated with distal right renal artery aneurysm. The operation was performed under combined thoracic epidural analgesia and general anesthesia using transperitoneal approach. After the laparotomy, the ascending colon was mobilized and reflected medially followed by Kocher maneuver. The result was visualization of the anterior aspect of the right kidney, the collecting system, ureter as well as the right renal vein and artery with large saccular aneurysm located distally. After mobilization of the renal vessels and careful dissection of the ureter, the kidney was explanted. The operation was continued by two surgical teams. The first team performed abdominal aortic aneurysm resection and reconstruction with bifurcated Dacron graft. The second team performed ex vivo reparation of renal artery aneurysm. All time during the explantation, the kidney was perfused by Collins' solution. The saccular right renal artery aneurysm 4 cm in diameter was located at the kidney hilus at the first bifurcation. Three branches originated from the aneurysm. The aneurysm was resected completely. The longest and widest of three branches arising from the aneurysmal sac was end-to-end anastomized with 6 mm PTFE graft. After this intervention, one of shorter arteries was implanted into the long artery, and another one into PTFE graft. After 30 minutes of explanation, autotransplantation of the kidney into the right iliac fossa was performed. The right renal vein was implanted into the inferior vein cava, and PTFE graft into the right limb of Dacron graft. Immediately following the completion of both anastomoses, large volume of urine was evident. Finally, ureteneocystostomy was performed with previous insertion of double "J" catheter. In the immediate postoperative period, renal function was restored to normal, while postoperative angiography revealed all patent grafts. DISCUSSION The most common causes of renal artery aneurysms are arteriosclerosis, as in our case, and fibro-muscular dysplasia. Very often, renal artery aneurysms are asymptomatic and discovered only during angiography in patients with aneurysmal and occlusive aortic disease. Other cases include: arterial hypertension, groin pain and acute or chronic renal failure. Due to relatively small number of evaluated cases, the risk of aneurysmal rupture is not known. According to some authors, the overall rupture rate of renal artery aneurysm is 5%, however, the rupture risk becomes higher in young pregnant woman. Several standard surgical procedures are available for the repair of renal artery aneurysms. These include saphenous vein angioplasty, bypass grafting, as well as ex vivo reconstruction with reimplantation or autotransplantation. Furthermore, interventional embolization therapy, as well as endovascular treatment with ePTFE covered stent, or autologous vein-coverage stent graft, have been also reported to be successful. CONCLUSION The major indications for surgical treatment of renal artery aneurysms are to eliminate the source of thromboembolism which leads to fixed renal hypertension and kidney failure, as well as prevention of aneurysmal rupture.

Abstract Renal Auto transplantation (RAT) is the surgical procedure in which the kidney is initially removed and subsequently re-implanted in a different position, allowing for improved outcomes in conditions involving ureteral pathology, renovascular and neoplastic disease primarily. In this paper, we aim to build upon the understanding of RAT and especially its effectiveness in treating patients with hypertension secondary to renal artery disease, intolerant to previous treatment approaches. In particular, the ex-vivo technique will be focused upon as introduced by Ota et al. in 1967 whereby the use of the workbench is frequently applied for patients requiring in excess of 45 minutes of ischaemic time. We, therefore, put forth two cases managed in co-operation by the University of Arkansas vascular and urology departments. The first of which was a 52-year-old woman with an aneurysmal Lesion reaching the renal artery at the hilum. The second was an 18-year-old woman with Takayasu arteritis. The use of vasopressin had preserved some renal function however at the time of the diagnosis, they were experiencing difficulty in controlling their hypertension, and thus RAT was performed, and the subsequent patient postoperative outcomes and effectiveness have been recorded and analysed as part of this study.
