An intermittent urethra self-retaining catheter set 10 comprises a catheter unit 1, a disinfectant casing 2, and a cap 3. The catheter unit 1 includes a catheter body 11 having an urine-guiding passage 111 and a water-guiding passage 112 that extend along a longitudinal direction and are separated from each other, a balloon 12 attached to a distal end of the catheter body 11 in an inflatable manner and communicated to the water-guiding passage 112, an elastic plug 13 attached to an intermediate portion of the catheter body 11, a branched tube 14 branched from the catheter body 11 above the elastic plug 13 and communicated to the water-guiding passage 112, a reservoir 16 attached to a free end of the branched tube 14 in a collapsible manner for storing a sterilized water 15, an on-off valve 17 attached to an intermediate portion of the branched tube 14, and a reinforcement tube 18 inserted into an upper interior of the urine-guiding passage 111 in the catheter body 11. The disinfectant casing 2 is detachably fitted on the elastic plug in a sealing manner for containing a lower part of the catheter body 11 below the elastic plug 13 and for storing a disinfectant liquid 21. The cap 3 is detachably fitted on a top portion of the catheter body 11 for opening and closing an outlet port 311. The on-off valve 17 is adapted to open and close a passage in which the sterilized water 15 flows between the reservoir 16 and the balloon 12.

An operation process of catheter placement will seriously stimulate a urethra and a bladder clinically, physiological and pathological stenosis and curve of the urethra of a human body will make it harder to place the catheter and will aggravate damage to a lower urinary tract in a placement process, and damage to the lower urinary tract will induce or aggravate lower urinary tract infection, which will further affect functions of the lower urinary tract or organs of the whole body. Methods for treating urethrostenosis currently include: 1, a high strength head or metallic probe bar or guide wire is used to enhance an external force to push the catheter, which will cause damage to an inner membrane of the urinary tract and even infection; 2, an outer surface of the urinary tract is paintedwith a lubricating oil or a lubricating coating, but the this method is not useful in urethrostenosis while being used independently. The invention provides a stenosis dilated catheter; and when thestenosis dilated catheter is placed, an expandable portion of a fin section of the head is filled, the urinary tract is painted with a lubricating agent, the placement successful rate is improved, andthe damage and infection risk is minimized.

A pressure sensing catheter system includes a urethral catheter and a sensor array formed on the urethral catheter. The sensor array includes a plurality of pressure sensors distributed along a length of the urethral catheter. The sensor array is configured to produce a dynamic pressure distribution profile along a urethra.

A urethral catheter and its method of use to identify a patient's urethral anatomic course for the precise placement of a treatment element into the patient's prostate are provided. An echo-opaque urethral catheter including an echogenic material and a radio-opaque material in at least an image portion thereof is introduced into a urethra until its echogenic and radio-opaque image portion is generally aligned with a treatment site of the prostate. An image probe positioned relative to the treatment site is activated to obtain a real time image of the prostate and urethra by ultrasound or X-ray imaging. The echo-opaque urethral catheter includes an elongated flexible catheter, at least the image portion of which, is coated with, incorporates within or is enclosed by the echogenic and radio-opaque materials that enhance ultrasound and radio visualization.

A non-bladder invasive urethral catheter system is provided as a system of apparatuses that provide a means relieving a user's urinary incontinence issues while reducing localized compression to the walls of their urethra. The non-bladder invasive urethral catheter system provides a more convenient and less intrusive means of enabling individuals suffering from urinary incontinence to live an ordinary life. The non-bladder invasive urethral catheter system provides the user with comfort and increased mobility and permits the user to maintain the indwelling catheter during urination. The apparatus blocks urine flow and leakage while installed within a user. The non-bladder invasive urethral catheter system utilizes several urethral catheters that are differentiated by the positioning of a urethral balloon element on the elongated body of the urethral catheter. Through the substitution of the differentiated urethral catheters, the user is able to reduce the trauma to a particular area of their urethra.

A method for insertion, maintenance, and removal of urethral catheters in mammals including humans includes steps for preventing or reducing the incidence of catheter associated urinary tract infections. In addition to sterile procedures currently practiced or as may be practiced in the future in connection with catheter use, the method includes the steps of applying an antiseptic, zwitterionic, and acidic skincare solution capable of preserving the stratum corneum to the perineum, meatus, and contiguous mucosa surrounding the insertion site before insertion, after insertion, periodically during the period of indwelling, in connection with any incidence of incontinence, and, optionally, before and after removal of the catheter. Application of the solution optionally is continued after catheter removal on a periodic basis until the threat of an infection associated with catheter use has passed, typically at least about five (5) to seven (7) days and up to thirty (30) days. The solution pH is desirably from about 4.4 to 5.5.
