Renova Système de néphrostomie

Un système spécialisé conçu pour les procédures de néphrostomie percutanée, offrant un drainage fiable et un accès au bassin rénal avec une précision accrue, un confort pour le patient et une efficacité procédurale.

Le 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.

Clinical Advantages & Applications

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.
