The Clinical Research Office of the Endourological Society Percutaneous Nephrolithotomy Global Study: Tract Dilation Comparisons in 5537 Patients

Abstract

The Global PCNL Study has identified differences in the method of dilation used between centers in Asia, Europe, and the United States. In the balloon dilation group, a total longer operative time and higher bleeding and transfusion rates were observed. The differences in outcome may be influenced by patient heterogeneity, including previous anticoagulation therapy or surgical procedures, in addition to the number of stones treated and rate of staghorn calculi, which were all higher in the balloon group.

Does Imaging Modality Used for Percutaneous Renal Access Make a Difference? A Matched Case Analysis

“…12,14 In addition, separate analyses of the CROES PCNL Global Study database reported elsewhere have shown that significant increases in bleeding and transfusion requirements in patients undergoing PCNL are associated with a larger sheath size and longer operating times 15 and are more likely with balloon dilation compared with telescopic/serial dilation. 16 Interestingly, there was no significant difference between the two groups in terms of mean change in hemoglobin in the present study. The fluoroscopy group had a higher multiple puncture rate compared to the ultrasound group.…”

A comparison of balloon and amplatz dilators in percutaneous nephrolithotomy: a retrospective evaluation

“…Procedural failure rate was higher in the balloon dilatation group. [7] However, very frequent use of balloon dilators in the management of larger staghorn stones, and operations performed in different medical centers with various indications were limitations of this study.…”

“…[17,18] The Clinical Research Office of the Endourological Society (CROES) has recently published the outcomes of a study related to PCNL performed in 5803 patients from 96 centers worldwide. [7] Observational analyses demonstrated that when compared with the patients who had undergone Amplatz dilatation, in patients who had experienced balloon dilatation lower bleeding (9.4 vs. 6.7%) and transfusion rates (7 vs. 4.9%) were detected. Procedural failure rate was higher in the balloon dilatation group.…”

“…Optimal dilatation method is debatable.Many dilatation methods including Amplatz, balloon, and metal telescopic dilatation are available. [6,7] In many international multicentered studies Amplatz dilators have been shown to be superior over balloon dilators. [7] With the development in balloon dilators, some studies also have demonstrated superiority of balloon dilators over Amplatz dilators.…”

“…[6,7] In many international multicentered studies Amplatz dilators have been shown to be superior over balloon dilators. [7] With the development in balloon dilators, some studies also have demonstrated superiority of balloon dilators over Amplatz dilators. [8] In this article, we compared use of Amplatz, and balloon dilators in consideration of pre-, and postoperative values.…”
