Our Experience with Retroperitoneal and Transperitoneal Laparoscopic Pyeloplasty for Pelvi-Ureteric Junction Obstruction

Overall our success rate following laparoscopic pyeloplasty is 88%. However, our preferred approach is transperitoneal, which is associated with a success rate of 92%. This is equivalent, if not better than that seen following open pyeloplasty with the additional benefits of reduced hospital stay and time to recovery. There are many possible explanations for this difference in success rates between approaches, however equivalent results are reported in the literature and therefore the learning curve is likely to be the major factor in this series.
