To share our experience performing laparoscopic pyeloplasty and our contributions to this surgery.Between March 2004 and January 2006 we have performed 12 laparoscopic pyeloplasties in 12 patients.

We also describe the advantages observed.With our technique we achieve an important surgical time reduction, improvements in safety and reduction of surgical complications.
