为了提高对移植肾输尿管梗阻患者的诊断与治疗水平，对在536例次肾移植患者中发现的13例输尿管梗阻患者进行临床总结分析，其中输尿管狭窄性梗阻10例，输尿管结石性梗阻3例。分析认为，肾移植术后早期排斥反应、伤口深部感染及漏尿可能与发生移植肾输尿管狭窄性梗阻有关，而肾移植术后高尿酸血症与输尿管结石形成有关。提出B超、肾图、经皮顺行造影和肾益内压测定为诊断移植肾输尿管梗阻的手段；对于输尿管狭窄性梗阻患者，早期经皮穿刺造疾引流术是挽救患者肾功能的关键，肾功能恢复后应尽快行经皮输尿管扩张置管术；对于移植肾输尿管结石性梗阻患者以保守治疗为宜。
In order to improve the diagnosis and treatment of patients with ureteral obstruction in renal transplantation, clinical analysis of 13 cases of ureteral obstruction found in 536 cases of renal transplantation patients, including ureteral stenosis obstruction in 10 cases, ureteral calculi obstruction in 3 cases. Analysis, early rejection after renal transplantation, wound infection and leakage of urine may occur with renal transplant stricture obstruction, and renal allograft hyperuricemia and ureteral stones related to the formation. B ultrasound, renal mapping, percutaneous parallel imaging and kidney YI pressure measurement for the diagnosis of ureteral obstruction in ureter; for patients with ureteral stricture, early percutaneous drainage is the key to saving patients with renal function, Percutaneous ureteral dilatation and catheterization should be performed as soon as possible after the recovery of renal function; conservative treatment is appropriate for patients with ureteral calculi obstruction.
