ABSTRACT:
The occlusion ureteral catheter for retrograde pyelography with a compression plate is a long slender catheter made of polyurethane radio opaque or any equivalent material. It has a central lumen which opens to both ends of the catheter. The catheter has three parts: the tip or head of the catheter, compression plate and the stem of the catheter. There are structural variations on the tip of the catheter and compression plate.
The tip of catheter has various shapes (whistle tip shape, cone or cobra head shape, olive tip shape and filiform shape), curvatures and sizes. The compression plate has various shapes (oval, circular, triangular) sizes and angulations. The compression plate is fixed and an integral part of the stem of the ureteral catheter. The occlusion ureteral catheter for retrograde pyelography comprises of a serial of catheters with structural variation at the tip and the compression plate.
The occlusion ureteral catheter for retrograde pyelography is manufactured to adapt to conventional cystoscopic or flexible endoscopic instructions.
The primary function of the occlusion ureteral catheter for retrograde pyelography is to create a watertight seal by compressing at the mucosa surrounding the ureteral orifice to prevent retrograde leakage of the contrast from the ureter to the urinary bladder, to produce an efficient positive pressure filling of the ureter and to reduce the radiation exposure to the patient, operator and personnel.
