离断性肾盂成形术治疗肾盂输尿管连接部狭窄32例

Dismembered pyeloplasty for treatment of ureteropelvic junction stricture:a report of 32 cases

摘要: 目的:探讨肾盂输尿管连接部(ureteropelvic junction,UPJ)狭窄的手术治疗方法。方法:32例均采用离断性肾盂成形术,术中置双J管引流,术后6~8周拔除双J管,3~6个月复查。结果:32例手术均获成功,排泄性尿路造影检查肾盂积水好转,狭窄解除,吻合口通畅。随访6个月,未出现吻合口再狭窄、肾积水加重等并发症。结论:离断性肾盂成形术是治疗UPJ狭窄的有效方法,使用有引流作用的支架管可减少术后再狭窄的发生。

Abstract: Objective: To evaluate the surgical effect of dismembered pyeloplasty on ureteropelvic junction (UPJ) stricture.Methods: A total of 32 cases of UPJ stricture were performed dismembered pyeloplasty with double pig-tail catheters.The double pig-tail catheter was removed 6-8 weeks after the operation.The outcome was evaluated 3-6 months later.Results: The operation was successful in all the 32 cases.Intravenous pelviureterograghy showed that the hydronephrosis was improved,the stricture relieved and the anastomotic stoma not obstructed.All the patients were followed up for six months.No complication occurred.Conclusions: Dismembered pyeloplasty is an effective method for treatment of UPJ stricture.Double pig-tail placement during operation can reduce the chance of UPJ restricture.
