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

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.
