"(《世界人权宣言》) Renova-DIRECT Nephrostomy system offers a comprehensive, versatile solution for kidney drainage in cases where percutaneous access is required—such as obstructions, stones, or post-surgical support. Designed for one-step or two-step insertion techniques, this system simplifies secure and efficient nephrostomy catheter placement. By combining a polyurethane (PUR) catheter, an ultrasound-visible puncture needle, an obturator/stylet, a Schüller guide wire, and a universal adapter, Renova-DIRECT supports safe, minimally invasive decompression of the renal collecting system.

Nephrostomy Catheter (PUR)
  • Biocompatible, Flexible Material: Made of soft, aliphatic polyurethane, minimizing trauma to renal tissue and ensuring comfortable dwell.
  • Tube for Stylet/Obturator & Needle Insertion: Streamlines one-step or two-step access, offering direct alignment of instruments via a single channel.
  • Luer-Lock Connector: Secures attachments for flushing, aspiration, or drainage bag connection.
  • Two-Part 18 G Needle (20 cm in length): Specifically designed for precise kidney entry under ultrasound guidance.
  • Ultrasound-Visible: Enhances safety by providing real-time imaging feedback for accurate puncture location in the renal collecting system.
  • Rounded Tip: Facilitates smooth advancement and straightening of the nephrostomy catheter during placement.
  • Secure Fit: Stabilizes the catheter shaft, reducing the risk of buckling or misalignment during insertion.
  • Uncoated Stainless Steel: Provides rigid, reliable track creation in the kidney’s collecting system or obstructed segments.
  • Sturdy: Enhances pushability and torque conduction for challenging anatomies.
  • Luer-Lock Connector & Funnel: Attaches seamlessly to a urinary drainage bag or other accessories, ensuring leakage-free drainage management.
  • 10 cm in Length: Offers adequate manipulation space and straightforward hooking to external drainage or infusion lines.

临床优势与应用

One-Step or Two-Step Placement
  • Streamlined Workflow: Operators can adopt a single-pass approach (one-step) for direct cannulation or a two-step method for staged access, depending on their preference or patient complexity.
  • Adaptable to Various Anatomies: The combined system accommodates both straightforward and challenging renal anatomies, minimizing the need for separate instrument sets.
  • Ultrasound-Visible Needle: Ensures safe puncture under real-time imaging, decreasing vascular or organ injury risk.
  • Stable Guide Wire Placement: Schüller wire fosters excellent track creation and reduces the chance of losing access during catheter transitions.
  • Soft, Temperature-Responsive PUR: Maintains structural resilience while softening in body-temperature conditions, diminishing patient discomfort.
  • Long-Term Performance: Tolerates multiple flushes or manipulations over extended indwelling periods if required by clinical indication.
  • Secure Luer-Lock: Tight seal with drainage tubing prevents accidental disconnections or fluid spillage.
  • Universal Adapter: Flexible interface allows for standard drainage bag coupling, simplifying patient management.
