Kumpe catheter

Last revised by Sonam Vadera on 23 Sep 2023

The Kumpe catheter, also known as KMP, is a selective access catheter designed for biliary and urinary tract cannulation, in order to secure access, navigate, advance, exchange devices, or deliver contrast in the target destination.

  • proximal end: luer lock hub

  • distal tip-shape: angle shaped

  • french size: 5F

  • length: 40 - 65 cm

  • recommend guidewire:

    • 0.038″ (0.97 mm)

  • maximum flow injection rate

    • These rates vary according to the manufacturer and should be verified in the catheter package

    • 19 mL/s at 82 bar /1200 psi

Percutaneous biliary duct access for

Percutaneous portal venous access for

Percutaneous renal access for

Endoscopic (cystoscopy) renal access for

  • ureteroscopy

Biliary ducts access

  1. flush the catheter

  2. after local anesthesia, and ultrasound/fluoroscopic-guided puncture of a biliary duct

  3. inject a small amount of contrast to confirm duct puncture on fluoroscopy

  4. insert an access wire and dilate the hepatic track with a 5F dilator

  5. perform a cholangiogram to confirm the position of the dilator

  6. remove the access wire and insert a stiff navigation wire (e.g. Stiff glidewire) and place it into target stenosis / or duodenum

  7. exchange the 5F dilator with a 7F short sheath catheter and perform a cholangiogram

  8. advance the KMP over the glidewire and into target destination

  9. retract the glidewire to allow the formation of the tip catheter

  10. once the stenosis is passed / reached target destination, deliver the rail wire through the catheter

  11. discard the catheter and mainain the access with the rail wire

To prevent biliary/urinary tract injury:

  • catheters should be inserted and withdrawn over wires, as the tip of catheters moving can cause injury

  • always verify the catheter pressure rate limit while using the power injector

  • in case of resistance while advancing or withdrawing the catheter, it is important to stop and identify the underlying cause of the resistance before proceeding further

  • avoid bending or kinking the catheter before its placement, as doing so may damage the catheter and lead to injury for the patient
