1. Technical Field
This document relates to methods and materials involved in holding tension on a urethral catheter and/or stabilizing the movement of a urethral catheter. For example, this document relates to devices configured to allow a physician to hold tension on a urethral catheter and to stabilize movement of a urethral catheter at the urethral meatus in a mammal (e.g., a human) in a non-invasive manner.
2. Background Information
Catheters are medical devices that can be used to facilitate various medical procedures. A catheter can be inserted into the body of a patient and thereby allow drainage or removal of fluids. For example, a typical urethral catheter is a Foley catheter. A Foley catheter is a flexible tube that is passed through the urethra and into the bladder. The catheter tube can have two lumens running along its length. One lumen is open at both ends allowing urine to drain out into a collection bag. The other lumen has a valve on the outside end and connects to a retention balloon at the tip. The retention balloon is inflated when it lies inside the bladder, to stop it from slipping out. The catheter tubing can be gently pulled on to apply force on the retention balloon.
This document provides methods and materials involved in holding tension on a urethral catheter and/or stabilizing the movement of a urethral catheter. For example, this document provides devices configured to allow a physician to hold tension on a urethral catheter and stabilize movement of a urethral catheter at the urethral meatus in a mammal (e.g., a human) in a non-invasive manner as well as methods for using catheter tension holding and movement stabilizing devices.
In some cases, it can be difficult to maintain tension on a urethral catheter. A catheter is often taped or strapped to a patient's leg in an attempt to maintain tension on the catheter. This can be uncomfortable for a patient, and the tape and catheter may not remain in place whereby the desired tension is lost. As described herein, catheter tension holding and movement stabilizing devices can be designed such that they attach to the urethral catheter tubing external to the urethral meatus. Urethral catheter tension holding and movement stabilizing devices can hold the catheter tubing tightly, allow tension to be applied to the catheter, and prevent the catheter tubing from sliding, thereby holding the desired tension on the catheter. Having the ability to prevent the catheter tubing from sliding in and out of the urethral meatus can also allow the physician to non-pharmacologically decrease the pain and discomfort associated with this sliding in and out motion for the patient. Reducing urethral catheter discomfort and pain to the patient when they move can give the patient more encouragement to move about and become ambulatory post-surgery. Having the ability to hold tension on a urethral catheter can allow the physician to treat medical conditions that respond to compression of the bladder neck and the organs that lie directly beneath the bladder (e.g., the male prostate) due to force applied to the retention balloon at the distal end of the urethral catheter. For example, hematuria (blood in the urine) of suspected prostatic origin, leaky anastomosis after prostatectomy, urine leakage around the catheter with bladder spasm and instilling intravesical chemotherapy after transurethral resection of bladder tumor (TURBT) are medical conditions that all respond positively to tension held on a urethral catheter. Having the ability to minimize catheter tube movement and/or apply and hold tension on a urethral catheter as described herein can relieve discomfort of catheterized patients and help aid in recovery of catheterized patients.
