A ureteric balloon catheter was a balloon catheter intended for the treatment of strictures of the ureter. In fact it was a double J stent on which a balloon was mounted. It was connected to a delivery device (pusher) which is used to introduce it from the bladder into the ureter. This system consists of non-return valve device & a pusher along with a stylet and 2 ports. The sideport used for the injecting contrast agent because to inflate the balloon, and the straight port used for the guidewire. The catheter was having a relatively large-diameter central lumen & a shaft with 2 mm (6 Fr.) length. The balloon is in 2 sections: a long narrow shaft or section and a larger cranial bulb. The larger cranial bulb will prevents distal migration and the longer narrow section will maintains the increased diameter of the predilated stricture in ureter section.
The guide wire has to be positioned in the ureter. After dilatation of the ureteric stricture with a elevated pressure dilatation balloon the guidewire remains in same place to bring the ureteric balloon catheter.
The balloon was inflated by a injection of contrast medium through sideport of the pusher and remains in situ and the expanded urothelium heals.
The stylet was used to remove the balloon catheter from the pusher. In the healing process the urine drains by a wide central lumen and the balloon remains inflated.
The ureteric balloon catheter will be used in the conjunction with a double J stent for extra or even more drainage. To take away the catheter after many weeks the balloon was deflated by a snipping the distal end of the catheter. The catheter will be then safely pulled out.
