[Correction of ureteropelvic junction syndrome: Anderson-Hynes method of pyeloplasty with or without nephrostomy].

We report the last 50 ureteropelvic junction repairs (Anderson-Hynes pyeloplasty) with a minimum follow-up of 6 months performed in our department. We describe the operative technique without nephrostomy in 40 patients and we look at the results in relation to a small group which had a nephrostomy for one or other reason (10 patients).
