Abstract:
1. A procedure for performing a controlled hydrodistention of a urinary bladder for a patient that, after an initial clinical evaluation, is determined to be a candidate for treatment for a bladder dysfunction, the procedure comprising: treating a bladder dysfunction in a patient by performing a controlled hydrodistention of a urinary bladder of said patient, the procedure further comprising: premedicating the patient with appropriate predetermined sedation medications such that the patient remains conscious and able to verbally communicate with a physician performing the procedure throughout the procedure; preparing the patient to be treated by placing the patient in a lithotomy position and performing a flexible cystoscopy with a topical anesthetic; providing a urological medical system for performing the controlled hydrodistention of the urinary bladder, the system comprising: inserting the catheter in the bladder of the patient and inflating said balloon with about 20 cc of sterile water draining said bladder; changing the patient's position to a more comfortable supine position; connecting the catheter to corresponding connections on the central microprocessing means and after a tubing from a fluid pump is primed with a warm sterile normal saline, connecting said tubing to the saline solution infusion channel of the catheter system; mixing a solution of a topical anesthetic, sodium bicarbonate and an anti-clotting drug in a syringe; securing said syringe in position against the patient's limb, slidingly engaging said catheter to said means for securing said syringe against the patients's limb, and infusing said mixture into the bladder via a tubing through the medicine infusion port of the medicine infusion channel of the catheter, and allowing said mixture to stay in the bladder for a predetermined time; adjusting a horizontal level of a tube holder supporting a tube attached to the pump means and holding the saline solution, to a desired level in relation to the patient's symphysis pubis; performing a titration procedure by infusing a warmed normal saline solution at the rate of about 50 cc per minute, wherein the saline solution flows from its source into the warmer means through the pump means and into the bladder; monitoring desired procedure parameters including procedure time, fluid infusion rate, fluid volume infused and intravesical pressure; verbally communicating with the patient at all times during the titration procedure wherein the patient is continuously reminded to express his physical sensations, and once the patient indicates there is pressure in the bladder and the sensation of the desire to urinate, the patient is asked to indicate how strong said sensations and once a maximum sensation level is reached, the pump means is stopped and notations are taken of time, infused volume, and intravesical pressure are made in the central microprocessing means, wherein at such time the parameters of volume infused and intravesical pressure are not to be exceeded, and maintaining the intravesical pressure for a predetermined time, at the expiration of which a main catheter port is opened and the bladder is drained and the volume as well as the color is inspected; and deflating the catheter balloon, and removing the catheter and the procedure is completed.
