RetroPerc®-A Prospective, Multi-institutional Trial of Efficacy of the RetroPerc Device
University of Kansas Medical Center
Summary
The goal of this observational study is to learn about the benefit of using RetroPerc® in obtaining renal access for percutaneous nephrolithotomy. The device is already used in routine clinical practice by urologists around the country. Participants who are already scheduled to undergo percutaneous nephrolithotomy as part of their regular care will be asked to participate.
Description
Retrograde nephrostomy access is well established as a safe method for nephrostomy creation and thus this study aims to perform a standard of care study. The device is already available, on the shelf, and used in routine clinical care. However, the study aims to take a closer look in a prospective fashion at this access technique to better understand specific variables that are not available on retrospective review of cases that have already undergone PCNL with this technique.
