Operative treatment of ureteropelvic junction obstruction

Objective To evaluate the clinical effect of double-pigtail catheter in Anderson-Hynes operation for the treatment of ureteropelvic junction obstruction(UPJO).Mechods From June 1994 to December 2005,a total of 42 cases of UPJO were treated by Anderson-Hynes operation and had a double-pigtail catheter placed.Every double-pigtail catheter was removed in one month after the operation.Outcome was evaluated with intravenous pelviureterography in 3 months.Results 40 cases were followedup for 3 months to 6 months.37 patients had fully recovered,with cure rate being 92.5%.3 cases had ureteropelvic junction(UPJ) stenosis,who were cured by a second operation.Conclusion Anderson-Hynes operation is an effective method for the treatment of UPJO.Double-pigtail catheter placement during operation can reduce the chance of UPJ re-stricture.
