Abstract: A specific catheter for percutaneous gastrostomy is indicated in all patients undergoing serious abdominal, general, or urologic surgical operations, or during the post-operatory period. This catheter is preferable to the naso-gastric tube which causes discomfort to patients and can be responsible for gastric erosions, gastritis, gastric bleeding, middle ear otitis, pulmonary atelectasis, and pneumonia. Moreover, this catheter is indicated for patients who require a prolonged enteral feeding. The catheter is positioned into the stomach at the end of the surgery through the abdominal wall, lateral to the abdominal incision by a percutaneous technique, and allows the best drainage of acid-mucous secretions from the stomach and duodenum. This catheter because of its material, its tip, its configuration inside the stomach, is a change from the traditional approach to patients improving their quality of life.

Abstract: The drainage catheter for continent urinary neo-bladders, is specific in all the cases to the reconstruction of the urinary bladder either when a tract of the intestine, or when a portion of the stomach is utilized after the surgical removal of the natural bladder. The catheter can be utilized either for orthotopic urinary neo-bladders (anastomosis to the urethra), or for neo-bladders with a stoma (anastomosis to the abdominal wall), and also in enlargement entero-cystoplasties, when the natural urinary bladder is enlarged utilizing different intestinal segments. The catheter is characterized by a wide draining surface for urine, having several holes, which plays a role in preventing dangerous inadvertent obstructions of neo-bladders in the post-operatory period, caused by the continuous formation of mucous clots, when the intestine has been utilized. This catheter also prevents and minimizes bleeding caused by acid secretions when a portion of the stomach has been utilized.
