ABSTRACT

Objectives:To evaluate the operative treatment for ureteropelvic junction(UPJ)stricture.Methods:A total of 58 cases of UPJ stricture had double-J tubes placed intraoperatively during Anderson-Hynes pyeloplasty.Urethral catheterization was maintained for 5~7 day,and the double-J tube was removed on cystoscopy 4 to 8 weeks after operation.The outcome was evaluated with ultrasonography or intravenous urography in 3 to 12 months postoperatively.Results:Success rate of management was 100%,stricture was relieved successfully in all patients,and hydronephrosis improved.Only 5 cases had complication in the near future.During follow-up of 6 months to 2 years,long-term complications,like stricture of the anastomotic mouth,and worsened kidney hydrocele,were not observed.all patients have been with satisfactory long-term results.Conclusions:Anderson-Hynes pyeloplasty was an effective method for the treatment of UPJ stricture.A double-J tubes in the operation could reduce the incidence of anastomotic mouth stricture and promote the success rate of operation.
