Objective To discuss the safety and feasibil ity of treating complex renal aneurysm with ex vivo aneurysmectomy and renal revascularization and renal autotransplantation after hand-assisted retroperitoneoscopic nephrectomy. Methods In October 2006, one male patient with complex renal aneurysm was treated. The preoperative color Doppler ultrasonograph, CT and DSA showed that there was an aneurysm (3.4 cm × 4.3 cm × 4.5 cm) located in the main renalartery bifurcation and its five branches of the left kidney. The patient had a history of hypertension with no response to treatment. After successful hand-assisted retroperitoneoscopic nephrectomy, the kidney off-body was perfused by the renal irrigating solution immediately to protect the kidney. Then ex vivo aneurysmectomy and renal artery revascularization were performed, the renal artery was reconstructed with an autologous right internal il iac artery. The reconstructed left kidney was re-implanted into the right il iac fossa. Results The operation was successful and the patient recovered without perioperative complications. The postoperative renal function was normal and the color Doppler ultrasonograph showed that the blood circulation in the transferred renal artery of the right il iac fossa and its branches was smooth, the blood circulation of the renal venous was smooth and no stenosis in the ureter 2 weeks after operation. Thirteen months follow-up showed the blood pressure was recovered to normal and the renal function was normal. Conclusion The method of ex vivo aneurysmectomy and autotransplantation is safe, feasible and minimally invasive for treating complex hilar renal artery aneurysms.

胰腺移植主要包括单独胰腺移植（pancreas transplantation alone, PTA）、肾移植后胰腺移植（pancreas after kidney transplantation, PAK）和胰肾联合移植（simultaneous pancreaskidney transplantation, SPK）。与其它实体大器官移植一样，胰腺移植成功的真正转折始于20世纪70年代末。随着新型免疫抑制剂的开发和应用、器官保存技术的改进和外科技术的日臻成熟，胰腺移植在全球范围内得到迅猛开展，胰腺移植受体及器官存活率显著提高。据国际胰腺移植登记中心（International Pancreas Transplant Registry, IPTR）记录，至2001年10月，全球已实施17 000余例胰腺移植，其中美国有11 500余例，胰腺移植后患者1年生存率超过95%，3年生存率接近90%； 移植胰腺1年和3年有功能生存率分别为83%和77%［1，2］。自1966年首例SPK在美国Minnesota大学成功实施以来，SPK已成为治疗Ⅰ型糖尿病合并肾功能衰竭的常规方法，全世界迄今为止已实施的胰腺移植中约90%采用该术式［3，4］。
【摘要】 目的 探讨肾移植术后药物（环孢素A和钙离子拮抗剂）、口腔卫生与牙龈增生的关系。 方法 随访2003年1月—2010年3月间321例肾移植患者，记录患者术后药物使用和口腔卫生情况，观察牙龈增生程度。结果 〖HTSS〗口腔卫生水平与牙龈增生程度之间存在统计学相关性（rs=0.344，P=0.000），口腔卫生水平越差，牙龈增生越严重。服用环孢素A和钙离子拮抗剂患者（A组）牙龈增生发生率为62.15%，高于单纯服用环孢素A患者（B组）23.40%，二者比较，差异有统计学意义（χ2=39.220，P=0.000）。结论 〖HTSS〗肾移植术后环孢素A和钙离子拮抗剂联合应用明显增加了牙龈增生的发病率。口腔卫生水平与牙龈增生程度之间存在重要关联，口腔卫生差是牙龈增生的危险因素。【Abstract】 Objective To investigate the correlation between drugs (cyclosporine A and calcium channel blocker), oral hygiene and gingival hyperplasia in patients after renal transplantation. Methods We continuously followed up 321 patients undergoing renal transplantation from January 2003 to July 2009 in our hospital. The levels of oral hygiene, medication and gingival hyperplasia were recorded. Results There was a close relationship between the level of oral hygiene and the degree of gingival hyperplasia (rs=0.344, P=0.000). Higher grades of gingival hyperplasia (grades Ⅱ and Ⅲ) were found exclusively in patients who did not have good oral hygiene. There was a higher tendency of developing gingival hyperplasia among patients who received cyclosporine A and calcium channel blocker than those who only received cyclosporine A (62.15% vs. 23.40%; χ2=39.220, P=0.000). Conclusion The prevalence of gingival hyperplasia is higher in renal transplant recipients taking cyclosporine A and calcium channel blockers. There is a significant relationship between the level of oral hygiene and the development of gingival hyperplasia. Poor oral hygiene is a risk factor of gingival hyperplasia.
ObjectiveTo systematically evaluate the efficacy and safety of enteric-coated mycophenolate sodium (EC-MPS) versus mycophenolate mofetil (MMF) in kidney transplant recipients. MethodsWe searched MEDLINE, EMbase, PubMed, the Cochrane Library (Issue 9, 2013), CBM, CNKI, VIP and WanFang Data from their inception to November 2013, to collect randomized controlled trials (RCTs) of EC-MPS versus MMF in kidney transplant recipients. References of included studies were also retrieved. Two reviewers independently screened studies according to the exclusion and inclusion criteria, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.1 software. ResultsA total of 8 RCTs involving 2 400 patients were included. The results of meta-analysis indicated that there were no significant differences between the two groups at the end of 4-week, 6-month, 12-month and 48-month follow-up in the acute rejection rate (4-weeks:RR=0.33, 95%CI 0.01 to 8.05; 6 months:RR=0.94, 95%CI 0.73 to 1.22; 12 months:RR=0.88, 95%CI 0.63 to 1.24; 4 years:RR=0.93, 95%CI 0.47 to 1.84). There were no significant differences between the two groups at the end of 6-month and 12-month follow-up in the chronic rejection rate (6 month:RR=0.66, 95%CI 0.27 to 1.58; 12 month:RR=0.57, 95%CI 0.29 to 1.15). There were no significant differences between the two groups at the end of 6-month, 12-month and 48-month follow-up in the graft loss or death rate (6-month:RR=0.79, 95%CI 0.41 to 1.50; 12-month:RR=0.76, 95%CI 0.40 to 1.43; 48-month:RR=1.38, 95%CI 0.59 to 3.23). As to the side effect, EC-MPS could significantly reduce the risk of pneumonia compared with MMF (RR=0.32, 95%CI 0.13 to 0.79). ConclusionBased on current evidences, EC-MPS is comparable with MMF for renal transplant patients in short-term effectiveness, and the incidence of pneumonia in the EC-MPS group is lower than the MMF group. Due to the limited quantity and quality of the studies, the conclusions should be validated by more high quality studies.
Objective To improve arterial anastomosis method for rat renal transplantation. Methods Renal transplantations were performed on 72 wistar rats. The donor superior mesenteric artery was end-to-end anastomosed to the recipient left renal artery by using of sleeve anastomosis technique. The external diameters of the vessels anastomosed were 0.60±0.05 mm (left renal artery) or 0.80±0.07 mm (superior mesenteric artery). The procedure consisted of a guidingsuture and two fixing sutures. The guiding suture was used to “telescope” therecipient left renal artery into the donor superior mesenteric artery about 2 millimetre. Two fixing sutures were applied 180°apart from each other and tied. Three sutures passed through all layers of the donor superior mesenteric artery andconstricted the vessel lumen, but only penetrated the adventitia of the recipient left renal artery. Results The time for arterial anastomoses was approximately 6 to 8 minutes. The renal grafts perfused very well after the recipient left renal artery clamp was removed. Complications included anastomotic hemorrhage(1 case) and thrombosis (1 case). Histologic examination of 34 grafts at different postoperative time ranging from 6 to 30 days revealed that renal artery was fully patent, with no evidence of ischemic injury. Conclusion The modified arterial sleeve anastomosis technique is simple and feasible regardless of experimentalcondition and can be easily performed.
