RetroPerc, Inc.

RetroPerc, Inc. manufactures specialized equipment and procedural kits for percutaneous nephrolithotomy (PCNL) and nephrostomy creation. The company's core product is the RetroPerc system, a device designed to improve renal protection and precision during percutaneous nephrostomy procedures by enabling alignment of the nephrostomy sheath with the infundibulum along the three-dimensional (X-Y-Z) axis. The system includes a puncture wire assembly with tip protection sheath, coaxial exchange catheter, 0.035" nephrostomy wire, balloon dilator, and nephrostomy sheath. RetroPerc's procedural approach positions a flexible ureteroscope in the selected infundibulum with the puncture apparatus advancing through the same anatomical pathway, thereby minimizing renal trauma compared to traditional approaches. The system is designed for modern urology practices and provides enhanced visualization during PCNL procedures. Products include puncture apparatus kits with pin-wise lock mechanisms, exchange catheters, and associated dilation and sheath components used in retrograde-access percutaneous renal surgery. The company serves urologists and urology-focused surgical centers performing stone management and percutaneous renal intervention procedures.
