目的　探讨肾移植术中常规应用连接式单J管输尿管支架 ,以降低肾移植术后输尿管的并发症发生率。方法　回顾性分析 15 6例肾移植术中常规应用连接式单J管的临床资料。前期 76例输尿管膀胱吻合采用Gregoir术式 ,后 80例采用Nesbit术式。术后随访 9个月至 2 5年。结果　 76例采用Gregoir术式的患者中 ,4例术后出现输尿管吻合口狭窄 ,均需开放手术治疗。全组 15 6例仅 1例发生输尿管吻合口瘘 ,保守治疗后痊愈。所有病例均无严重尿路感染等并发症。结论　肾移植术中常规应用连接式单J管输尿管支架 ,是降低肾移植术后输尿管并发症的简便易行且安全有效的方法。 Objective To investigate the routine application of single J tube ureteral stent in renal transplantation to reduce the incidence of ureteral complications after renal transplantation. Methods A retrospective analysis of 15 6 cases of renal transplantation in the conventional application of single J-tube clinical data. The first 76 cases of ureteral anastomosis using Gregoir surgery, followed by 80 cases of Nesbit operation. The patients were followed up for 9 months to 25 years. Results Of 76 patients with Gregoir’s surgery, 4 patients had ureteral anastomotic stenosis and were treated with open surgery. The group of 15 cases of only 1 case of ureteral anastomotic leakage, conservative treatment after recovery. No serious complications such as urinary tract infection were found in all cases. Conclusion The routine application of the single J-tube ureteral stent in renal transplantation is a simple, safe and effective method to reduce the complications of ureter after renal transplantation.
