总结１９９０～１９９３年４年间的临床肾移植４１１例，重点探讨移植肾输尿管３种并发症的发生原因、预防及治疗方法。认为尿漏的发生与取肾、修肾过程中输尿管系膜的保护不够以及输尿管膀胱吻合的技巧有直接关系。输尿管狭窄多为粘膜下隧道缝合过紧。急性输尿管梗阻为异物所致。尿漏、输尿管狭窄应早期手术治疗，而急性梗阻则可先行局部按压或颠簸治疗，不能通畅者也应手术解除。
Summarize the clinical renal transplantation from 1990 to 1993 four years of 411 cases, focusing on three reasons for the occurrence of renal transplant ureter complications, prevention and treatment. That the occurrence of urinary leakage and kidney, kidney repair process of inadequate protection of the mesangial and ureteral bladder anastomosis skills are directly related. Ureteral stenosis mostly submucosal tunnel suture too tight. Acute ureteral obstruction caused by foreign body. Urine leakage, ureteral stricture should be early surgical treatment, and acute obstruction can be partial pressure or bumpy treatment, who can not be removed should be surgery.
