Device for pericatheter retrograde

摘要

A pericatheter device is disclosed for enabling the introduction of contrast medium into the urethra and bladder neck of a patient with a catheter indwelling to enable radiographic visualization without removal of the catheter. The device has a crescent-shaped elongate member, a mating member for mating with a syringe, and a spacer member coupling the elongate member and mating member. A straight through-bore is provided from the mating member through the spacer member and through the elongate member so that a liquid contrast medium can be injected therethrough.
