JJ Catheter

The Overtoom JJ Catheter® OJJC represents a major breakthrough in the treatment of ureteric obstruction.

 Advantage in case of a downstream approach:

A second channel in the pusher as well as in the JJ catheter allows the user to inject contrast medium at two different chosen levels:

1.    One contrast exit point at the tip and one contrast exit point at the site of the connection.

One contrast exit point at the tip, why an advantage?

When the urine flow is completely blocked, the position of the tip can be made visible at any moment of the procedure by contrast medium and fluoroscopy while the guide wire can remain in place. Specially in case of obstruction of the ureter by tumor this catheter is extremely useful.

2.    One contrast exit point at the site of the connection between pusher and catheter.

When the contrast medium in the pyelum has been washed out, a control injection can be given while the guidewire can remain in place, to make sure the connection is actually in the pyelum in order not to leave the catheter in the cortex of the kidney, or even worse, outside the capsule of the kidney into the peri renal fat.

Advantage in case of an upstream approach:

When a stone or other kind of obstruction has to be passed by a guidewire and a double J catheter, the guidewire can remain in place while contrast can be injected to make the ureter visible for guidewire manipulations.

By using this second channel for contrast injections and fluoroscopy, with this double lumen catheter, the procedure can be done in a considerable shorter timeframe and with more control of guidewire manipulations and the position in which the catheter is left.
