ABSTRACT OF THE DISCLOSURE A suprapubic catheterization system features a suprapubic catheter having an advantageously large drainage lumen that con- sists of a stylet with a thin wall catheter external to it. The stylet is a combination of a trocar or puncturing device that pre- vents tissue coring and a hollow cannula having side openings thereon that coincide with openings on the external catheter. The openings on the cannula and catheter permit urine to flow through the proximal end thereof, thereby indicating that both tro- car and catheter are positioned correctly well inside the bladder. The inner stylet can then be removed and a routine hook-up to the catheter can be accomplished. The catheter tip may be coiled so as to assist in the retention of the catheter intracystically. Irrigation of the bladder can be simply accomplished by inserting a luer fitting syringe into the system for irrigating a blocked catheter or the like. The catheter may also be provided with a slidable locking mechanism for stabilizing the longer internal stylet type of catheter. A preferred collet type device can be slid down the external catheter to a desired and convenient length prior to insertion and is locked in place, and can be made to have an adhesive coating on a side thereof so that the catheter may be affixed on the skin of the abdomen to prevent pull-out after its installation and during drainage. The entire catheterization system can be pre-connected for ease of use and storage, and yet the individual portions thereof can be easily disconnected and separated from each other when used on a patient, for application of irrigation, sampling and medicine installation.
