Introduction: Nephrostomy tract dilation is one of the important steps of percutaneous renal surgery. In this study, we present our initial experience with the balloon dilator in 95 patients and compare our results retrospectively with a group of 30 patients in whom Amplatz dilators were used. Patients and Methods: The medical records of 95 patients who underwent percutaneous renal operations, including percutaneous nephrolithotomy and antegrade endopyelotomy, between September 1999 and September 2002 were reviewed. All procedures were performed using balloon dilators. The operative technique is the same as the other dilation procedures. Thirty consecutive patients who had previously undergone percutaneous renal surgery using the Amplatz dilators were taken as the control group and their charts were reviewed retrospectively, and the results compared with the results of patients in whom balloon dilation was used. Results: There were no major perioperative complications or deaths in both groups. The mean operative time and tract formation times for the balloon dilation group and the Amplatz dilation group were 106.8 ± 41.4 and 11.2 ± 3.0, and 116.4 ± 23.7 and 16.3 ± 2.4 min, respectively. Thirteen (13.7%) patients had significant bleeding and required blood transfusion in the balloon dilation group, whereas 5 (16.6%) patients had significant bleeding in the Amplatz dilation group. Collecting system perforation due to too far advancement of the dilator occurred in 11 (11.6%) patients but there was no major parenchymal or vascular injury medially in the balloon dilation group. On the other hand, collecting system perforation occurred during sequential Amplatz dilation in 5 (16.6%) patients. Conclusion: We believe that the balloon system allows one-step dilation and shortens the dilation procedure. It may minimize bleeding which can occur during the stepwise fascial dilation. When using fascial dilators it is sometimes possible to go out of the collecting system by changing the size of the dilators. We think that balloon dilation may prevent these intraoperative and time-consuming situations.
