An improved outlet tube device for a urinary drainage bag is disclosed wherein an outlet valve mechanism is contained with a rigid housing fixed securely to the drainage bag, rather than just being clamped to the outlet tubing, and thus cannot become separated from the bag. The outlet valve can be opened only by positive action on the part of the medical care personnel, thereby assuring that urine will be discharged only in a controlled manner. Further, because the valve mechanism does not require that a substantial length of tubing with a freely movable end be used in conjunction with the outlet port, there is no need to engage the free end of the tubing with a keeper. Thus the possibility of the tubing springing back to its straight configuration and flicking residual urine on the attending medical personnel is eliminated. In one embodiment the outlet tube device comprises a pinchcock-type valve which is fixedly mounted to the bag and which is normally operative to clamp off the outlet tube. In a second embodiment the outlet tube device comprises a syringetype fitting which is fixedly mounted to the bag. Depressing the syringe plunger closes the valve, and retracting the plunger opens the valve to permit fluid to be discharged through the outlet tube. In a third embodiment, a hose clamp is contained within a rigid housing and is selectively operative to clamp a hose to prevent fluid flow therethrough.

The retention balloon of the Foley urinary drainage catheter is replaced by a new self-retaining system. This new self-retaining catheter eliminates the problem of residual urine and also of bladder wall irritation caused by continuous contact with a spherical retention balloon; it also does not rely on a stylet for placement. The new system may use an internal control wire that reversibly foreshortens the proximal end of the catheter thus radially displacing longitudinal strips defined in the proximal catheter to form retention wings. Alternatively, a balloon situated between the longitudinal strips is inflated to force open the retention wings once inside the urinary bladder. Radial displacement of the retention wings widens the spaces between the longitudinal strips, these spaces constituting the drainage apertures which permit complete emptying of the urinary bladder, thereby eliminating a source of bladder irritation. The radially displaced retention wings abut the bladder wall in a non-continuous manner thereby reducing the area of bladder-catheter contact and further reducing bladder wall irritation.

A partial-length catheter, or an extendable tube or sleeve member of the catheter, is selectively movable within the prostatic urethra to open a urine drainage passageway through and obstructed portion of the prostatic urethra or to open the external urinary sphincter muscle and thereby discharge urine from the bladder. A control element is manipulated at a position exterior of the urinary canal to selectively move the catheter or the extendable tube or sleeve member, thereby selectively controlling urine discharge. The catheter may also be used to diagnose urinary retention problems caused by a weak bladder or a prostatic obstruction.
